We look at the division of 72122363 by 636 
The aim is to understand the frequency of 636 in 72122363.

Let's proceed to step 1:
If we divide 7 by 636, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 636

Step 2:
72 divided by 636 is 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Append the next digit (1) from the dividend to 72 and continue with: 721 / 636

Step 3:
721 divided by 636 is 1 with a remainder of 85.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 636 from 721, we get 85.
Append the next digit (2) from the dividend to 85 and continue with: 852 / 636

Moving on to step 4:
If we divide 852 by 636, we get 1 and a remainder of 216.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 636 from 852 to get 216.
Fetch the next digit (2) from the dividend, attach it to 216 and continue: 2162 / 636

Let's proceed to step 5:
When dividing 2162 by 636, we get 3 with a remainder of 254.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
The remainder is 254 after subtracting 1908 from 2162.
Fetch the next digit (3) from the dividend, attach it to 254 and continue: 2543 / 636

Moving on to step 6:
636 can be fit into 2543 3 times, resulting in a remainder of 635.
The next digit of our result is 3. 
Result so far: 1133.0
If we subtract 1908 from 2543, we get 635.
Append the next digit (6) from the dividend to 635 and continue with: 6356 / 636

Advancing to step 7:
The number 636 fits into 6356 9 times, leaving a remainder of 632.
Put 9 as the next digit of the answer. 
Result so far: 11339.0
If we take 5724 away from 6356, we end up with 632.
Grab the next digit (3) from the dividend, add it to 632, then carry on: 6323 / 636

Advancing to step 8:
6323 divided by 636 is 9 with a remainder of 599.
Record the quotient 9 as the next digit in the result. 
Result so far: 113399.0
Subtract 5724 from 6323 to get 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Let's proceed to step 9:
5990 divided by 636 is 9 with a remainder of 266.
Use 9 as the next digit of our solution. 
Result so far: 113399.9
Subtract 5724 from 5990 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Let's proceed to step 10:
636 goes into 2660 4 times with a remainder of 116.
The next digit of our result is 4. 
Result so far: 113399.94
The remainder is 116 after subtracting 2544 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 11:
If we divide 1160 by 636, we get 1 and a remainder of 524.
The number 1 becomes the next digit in our result. 
Result so far: 113399.941
If we subtract 636 from 1160, we get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Advancing to step 12:
The number 636 fits into 5240 8 times, leaving a remainder of 152.
Write down 8 as next digit of the result. 
Result so far: 113399.9418
Deduct 5088 from 5240 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 13:
636 goes into 1520 2 times with a remainder of 248.
Put 2 as the next digit of the answer. 
Result so far: 113399.94182
Subtracting 1272 from 1520 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 14:
636 goes into 2480 3 times with a remainder of 572.
The number 3 becomes the next digit in our result. 
Result so far: 113399.941823
If we take 1908 away from 2480, we end up with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Advancing to step 15:
636 goes into 5720 8 times with a remainder of 632.
Use 8 as the next digit of our solution. 
Result so far: 113399.9418238
If we take 5088 away from 5720, we end up with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Step 16:
The number 636 fits into 6320 9 times, leaving a remainder of 596.
Write down 9 as next digit of the result. 
Result so far: 113399.94182389
Deduct 5724 from 6320 and we're left with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

The final result is 113399.94182389 with a remainder of 5.96e-07.
