Let's divide 32991010 by 809
The aim is to understand the frequency of 809 in 32991010.

On to step 1:
809 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 809

Going ahead to step 2:
32 divided by 809 is 0 with a remainder of 32.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 32, we end up with 32.
Bring next digit (9) of the dividend behind the 32 and repeat the process: 329 / 809

On to step 3:
809 goes into 329 0 times with a remainder of 329.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 329 to get 329.
Include the next digit (9) from the dividend after 329, then repeat: 3299 / 809

Let's proceed to step 4:
809 can be fit into 3299 4 times, resulting in a remainder of 63.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 3236 from 3299 leaves us with 63.
Bring next digit (1) of the dividend behind the 63 and repeat the process: 631 / 809

Going ahead to step 5:
631 divided by 809 is 0 with a remainder of 631.
The next digit of our result is 0. 
Result so far: 40.0
If we take 0 away from 631, we end up with 631.
Fetch the next digit (0) from the dividend, attach it to 631 and continue: 6310 / 809

Step 6:
809 can be fit into 6310 7 times, resulting in a remainder of 647.
The next digit of our result is 7. 
Result so far: 407.0
Subtracting 5663 from 6310 leaves us with 647.
Append the next digit (1) from the dividend to 647 and continue with: 6471 / 809

Advancing to step 7:
6471 divided by 809 is 7 with a remainder of 808.
Put 7 as the next digit of the answer. 
Result so far: 4077.0
The remainder is 808 after subtracting 5663 from 6471.
Take the next digit (0) from the dividend and append it to 808, then repeat: 8080 / 809

Step 8:
If we divide 8080 by 809, we get 9 and a remainder of 799.
Write down 9 as next digit of the result. 
Result so far: 40779.0
Deduct 7281 from 8080 and we're left with 799.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7990, and continue the process.

Going ahead to step 9:
7990 divided by 809 is 9 with a remainder of 709.
The next digit of our result is 9. 
Result so far: 40779.9
Subtract 7281 from 7990 to get 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Advancing to step 10:
809 goes into 7090 8 times with a remainder of 618.
The next digit of our result is 8. 
Result so far: 40779.98
If we subtract 6472 from 7090, we get 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Advancing to step 11:
809 can be fit into 6180 7 times, resulting in a remainder of 517.
Record the quotient 7 as the next digit in the result. 
Result so far: 40779.987
Subtract 5663 from 6180 to get 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Step 12:
809 can be fit into 5170 6 times, resulting in a remainder of 316.
Put 6 as the next digit of the answer. 
Result so far: 40779.9876
Subtracting 4854 from 5170 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 13:
If we divide 3160 by 809, we get 3 and a remainder of 733.
Put 3 as the next digit of the answer. 
Result so far: 40779.98763
If we subtract 2427 from 3160, we get 733.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7330, and continue the process.

Let's proceed to step 14:
809 goes into 7330 9 times with a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 40779.987639
The remainder is 49 after subtracting 7281 from 7330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 15:
490 divided by 809 is 0 with a remainder of 490.
Put 0 as the next digit of the answer. 
Result so far: 40779.987639
If we take 0 away from 490, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 16:
809 can be fit into 4900 6 times, resulting in a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 40779.98763906
If we subtract 4854 from 4900, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 40779.98763906 with a remainder of 4.6e-08.
