We look at the division of 75725157 by 636 
The aim is to understand the frequency of 636 in 75725157.

Advancing to step 1:
The number 636 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 636

Moving on to step 2:
75 divided by 636 is 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Grab the next digit (7) from the dividend, add it to 75, then carry on: 757 / 636

Advancing to step 3:
757 divided by 636 is 1 with a remainder of 121.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 636 from 757 to get 121.
Fetch the next digit (2) from the dividend, attach it to 121 and continue: 1212 / 636

Moving on to step 4:
1212 divided by 636 is 1 with a remainder of 576.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 636 away from 1212, we end up with 576.
Grab the next digit (5) from the dividend, add it to 576, then carry on: 5765 / 636

Advancing to step 5:
When dividing 5765 by 636, we get 9 with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 119.0
If we take 5724 away from 5765, we end up with 41.
Append the next digit (1) from the dividend to 41 and continue with: 411 / 636

On to step 6:
The number 636 fits into 411 0 times, leaving a remainder of 411.
Put 0 as the next digit of the answer. 
Result so far: 1190.0
The remainder is 411 after subtracting 0 from 411.
Fetch the next digit (5) from the dividend, attach it to 411 and continue: 4115 / 636

Going ahead to step 7:
636 can be fit into 4115 6 times, resulting in a remainder of 299.
The number 6 becomes the next digit in our result. 
Result so far: 11906.0
Deduct 3816 from 4115 and we're left with 299.
Bring next digit (7) of the dividend behind the 299 and repeat the process: 2997 / 636

Advancing to step 8:
636 goes into 2997 4 times with a remainder of 453.
Put 4 as the next digit of the answer. 
Result so far: 119064.0
If we take 2544 away from 2997, we end up with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

On to step 9:
The number 636 fits into 4530 7 times, leaving a remainder of 78.
The next digit of our result is 7. 
Result so far: 119064.7
If we subtract 4452 from 4530, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 10:
The number 636 fits into 780 1 times, leaving a remainder of 144.
Write down 1 as next digit of the result. 
Result so far: 119064.71
The remainder is 144 after subtracting 636 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 11:
636 can be fit into 1440 2 times, resulting in a remainder of 168.
Write down 2 as next digit of the result. 
Result so far: 119064.712
The remainder is 168 after subtracting 1272 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 12:
636 can be fit into 1680 2 times, resulting in a remainder of 408.
Put 2 as the next digit of the answer. 
Result so far: 119064.7122
If we take 1272 away from 1680, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

After the division, we end up with 119064.7122 and a remainder of 0.00408.
