155432 divided by 72 
The aim is to understand the frequency of 72 in 155432.

On to step 1:
72 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 72

Moving on to step 2:
15 divided by 72 is 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 72

Going ahead to step 3:
When dividing 155 by 72, we get 2 with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 144 from 155 leaves us with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 72

Going ahead to step 4:
114 divided by 72 is 1 with a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we subtract 72 from 114, we get 42.

On to step 5:
The number 72 fits into 423 5 times, leaving a remainder of 63.
Use 5 as the next digit of our solution. 
Result so far: 215.0
Subtract 360 from 423 to get 63.
Fetch the next digit (2) from the dividend, attach it to 63 and continue: 632 / 72

Moving on to step 6:
When dividing 632 by 72, we get 8 with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 2158.0
Deduct 576 from 632 and we're left 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.

Advancing to step 7:
560 divided by 72 is 7 with a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 2158.7
The remainder is 56 after subtracting 504 from 560.
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 8:
560 divided by 72 is 7 with a remainder of 56.
Put 7 as the next digit of the answer.
