We look at the division of 72237130 by 636 
The aim is to understand the frequency of 636 in 72237130.

Advancing to step 1:
636 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 636

Step 2:
72 divided by 636 is 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Bring next digit (2) of the dividend behind the 72 and repeat the process: 722 / 636

Step 3:
If we divide 722 by 636, we get 1 and a remainder of 86.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 636 from 722 and we're left with 86.
Take the next digit (3) from the dividend and append it to 86, then repeat: 863 / 636

Going ahead to step 4:
The number 636 fits into 863 1 times, leaving a remainder of 227.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 636 from 863 leaves us with 227.
Append the next digit (7) from the dividend to 227 and continue with: 2277 / 636

Going ahead to step 5:
636 can be fit into 2277 3 times, resulting in a remainder of 369.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
Subtract 1908 from 2277 to get 369.
Bring next digit (1) of the dividend behind the 369 and repeat the process: 3691 / 636

Going ahead to step 6:
When dividing 3691 by 636, we get 5 with a remainder of 511.
Put 5 as the next digit of the answer. 
Result so far: 1135.0
If we take 3180 away from 3691, we end up with 511.
Grab the next digit (3) from the dividend, add it to 511, then carry on: 5113 / 636

Moving on to step 7:
The number 636 fits into 5113 8 times, leaving a remainder of 25.
Write down 8 as next digit of the result. 
Result so far: 11358.0
If we subtract 5088 from 5113, we get 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 636

Going ahead to step 8:
If we divide 250 by 636, we get 0 and a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 113580.0
If we take 0 away from 250, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 9:
636 goes into 2500 3 times with a remainder of 592.
The next digit of our result is 3. 
Result so far: 113580.3
Subtracting 1908 from 2500 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

On to step 10:
The number 636 fits into 5920 9 times, leaving a remainder of 196.
Record the quotient 9 as the next digit in the result. 
Result so far: 113580.39
The remainder is 196 after subtracting 5724 from 5920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 11:
1960 divided by 636 is 3 with a remainder of 52.
Record the quotient 3 as the next digit in the result. 
Result so far: 113580.393
Subtracting 1908 from 1960 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 12:
When dividing 520 by 636, we get 0 with a remainder of 520.
The next digit of our result is 0. 
Result so far: 113580.393
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 13:
If we divide 5200 by 636, we get 8 and a remainder of 112.
The number 8 becomes the next digit in our result. 
Result so far: 113580.39308
Subtract 5088 from 5200 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 14:
1120 divided by 636 is 1 with a remainder of 484.
The next digit of our result is 1. 
Result so far: 113580.393081
The remainder is 484 after subtracting 636 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Let's proceed to step 15:
When dividing 4840 by 636, we get 7 with a remainder of 388.
Use 7 as the next digit of our solution. 
Result so far: 113580.3930817
Subtract 4452 from 4840 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

On to step 16:
If we divide 3880 by 636, we get 6 and a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 113580.39308176
If we subtract 3816 from 3880, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 113580.39308176, and the remainder is 6.4e-08.
