So I got this dataframe (dataframe 1):
# A tibble: 6 x 27
# Groups: authority_dic, Full.Name [6]
authority_dic Full.Name Entity `4_2020` `3_2020` `7_2020` `12_2019` `8_2020` `5_2019` `1_2019` `4_2019` `6_2019` `8_2019` `9_2020` `10_2019` `11_2020` `9_2019`

Now I want to create another dataframe (dataframe 3) and it should contain all names of the column "full name" and divide all columns values of dataframe 1 "x_20xx" through the matching value of dataframe 2. It's kind of tricky, because unfortunately, both dataframes got the exact same column names for "x_20xx". Maybe we need to change that first in order to calculate the values for the new dataframe.
This is an example of what I want: Obviously with all the "x_20xx" columns.
Full.Name `1_2019_freq`
<chr> <int>
1 A (value_1_2019 df1) / (value_1_2019 df2)
2 B (value_1_2019 df1) / (value_1_2019 df2)
3 C (value_1_2019 df1) / (value_1_2019 df2)
4 D (value_1_2019 df1) / (value_1_2019 df2)
5 E (value_1_2019 df1) / (value_1_2019 df2)
6 F (value_1_2019 df1) / (value_1_2019 df2)
It's hard to explain, but I hope you get my point. It's a simple calculation, but I am not able to group all "A" and "B" [...] and sum their columns so that there is only one row containing "A" with all the other months but summed values for each month. After that, we only need to create another new dataframe and divide the values through the matching values of df2.
Any help is appreciated.
Many thanks for considering my request.

Take "John J. Legere" as an example.
As usual, working with wide data is hard, but working long is easy:
inner_join(
pivot_longer(df1, cols=4:27, names_to="period") %>% group_by(Full.Name, period) %>% summarize(value=sum(value,na.rm=T), .groups="drop"),
pivot_longer(df2, cols=2:25, names_to="period") %>% group_by(Full.Name, period) %>% summarize(value=sum(value,na.rm=T), .groups="drop"),
by=c("Full.Name", "period")
) %>%
mutate(result = value.x/value.y) %>%
pivot_wider(id_cols = Full.Name, names_from="period", values_from="result")
Change to left_join() if you want to retain names from df1 that don't appear in df2
Output:
# A tibble: 1 × 25
Full.Name `1_2019` `1_2020` `10_2019` `10_2020` `11_2019` `11_2020` `12_2019` `12_2020` `2_2019` `2_2020` `3_2019` `3_2020` `4_2019` `4_2020` `5_2019` `5_2020`

Note that the group_by/summarize after pivoting df2 can be dropped if the there is only one row per Full.Name in that frame. Also, notice that the summing using na.rm=T, which is probably what you want, but also results in zeros in value.y, resulting in lots of dividing by zero.
