Let's divide 51684536 by 72
The aim is to understand the frequency of 72 in 51684536.

Advancing to step 1:
72 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 72

On to step 2:
If we divide 51 by 72, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Take the next digit (6) from the dividend and append it to 51, then repeat: 516 / 72

On to step 3:
If we divide 516 by 72, we get 7 and a remainder of 12.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 504 from 516, we get 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 72

Step 4:
128 divided by 72 is 1 with a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
If we take 72 away from 128, we end up with 56.
Include the next digit (4) from the dividend after 56, then repeat: 564 / 72

Step 5:
564 divided by 72 is 7 with a remainder of 60.
The next digit of our result is 7. 
Result so far: 717.0
Subtract 504 from 564 to get 60.
Grab the next digit (5) from the dividend, add it to 60, then carry on: 605 / 72

On to step 6:
72 goes into 605 8 times with a remainder of 29.
Write down 8 as next digit of the result. 
Result so far: 7178.0
If we subtract 576 from 605, we get 29.
Include the next digit (3) from the dividend after 29, then repeat: 293 / 72

Advancing to step 7:
When dividing 293 by 72, we get 4 with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 71784.0
The remainder is 5 after subtracting 288 from 293.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 72

Going ahead to step 8:
When dividing 56 by 72, we get 0 with a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 717840.0
Subtract 0 from 56 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
560 divided by 72 is 7 with a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 717840.7
If we take 504 away from 560, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
72 can be fit into 560 7 times, resulting in a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 717840.77
Subtract 504 from 560 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 717840.77, and the remainder is 0.056.
