We're dividing 20956886 by 636 
The aim is to understand the frequency of 636 in 20956886.

Moving on to step 1:
2 divided by 636 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 636

Advancing to step 2:
636 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 636

Advancing to step 3:
When dividing 209 by 636, we get 0 with a remainder of 209.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 209 leaves us with 209.
Grab the next digit (5) from the dividend, add it to 209, then carry on: 2095 / 636

Step 4:
When dividing 2095 by 636, we get 3 with a remainder of 187.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 1908 from 2095 and we're left with 187.
Bring next digit (6) of the dividend behind the 187 and repeat the process: 1876 / 636

Let's proceed to step 5:
When dividing 1876 by 636, we get 2 with a remainder of 604.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we take 1272 away from 1876, we end up with 604.
Bring next digit (8) of the dividend behind the 604 and repeat the process: 6048 / 636

Moving on to step 6:
6048 divided by 636 is 9 with a remainder of 324.
The number 9 becomes the next digit in our result. 
Result so far: 329.0
Deduct 5724 from 6048 and we're left with 324.
Take the next digit (8) from the dividend and append it to 324, then repeat: 3248 / 636

Moving on to step 7:
When dividing 3248 by 636, we get 5 with a remainder of 68.
Use 5 as the next digit of our solution. 
Result so far: 3295.0
Subtract 3180 from 3248 to get 68.
Take the next digit (6) from the dividend and append it to 68, then repeat: 686 / 636

On to step 8:
636 goes into 686 1 times with a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 32951.0
Subtract 636 from 686 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
The number 636 fits into 500 0 times, leaving a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 32951.0
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 10:
The number 636 fits into 5000 7 times, leaving a remainder of 548.
The number 7 becomes the next digit in our result. 
Result so far: 32951.07
Subtract 4452 from 5000 to get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Let's proceed to step 11:
636 goes into 5480 8 times with a remainder of 392.
Use 8 as the next digit of our solution. 
Result so far: 32951.078
Subtract 5088 from 5480 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 12:
When dividing 3920 by 636, we get 6 with a remainder of 104.
Write down 6 as next digit of the result. 
Result so far: 32951.0786
If we take 3816 away from 3920, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 13:
1040 divided by 636 is 1 with a remainder of 404.
Write down 1 as next digit of the result. 
Result so far: 32951.07861
If we take 636 away from 1040, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 14:
4040 divided by 636 is 6 with a remainder of 224.
The next digit of our result is 6. 
Result so far: 32951.078616
The remainder is 224 after subtracting 3816 from 4040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 15:
2240 divided by 636 is 3 with a remainder of 332.
Record the quotient 3 as the next digit in the result. 
Result so far: 32951.0786163
Subtract 1908 from 2240 to get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 16:
If we divide 3320 by 636, we get 5 and a remainder of 140.
The number 5 becomes the next digit in our result. 
Result so far: 32951.07861635
If we take 3180 away from 3320, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final result is 32951.07861635 with a remainder of 1.4e-07.
