508135 ÷ 72 
The aim is to understand the frequency of 72 in 508135.

Moving on to step 1:
The number 72 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 72

Going ahead to step 2:
72 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Grab the next digit (8) from the dividend, add it to 50, then carry on: 508 / 72

Moving on to step 3:
72 can be fit into 508 7 times, resulting in a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 504 from 508, we get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 72

Advancing to step 4:
41 divided by 72 is 0 with a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 70.0
If we take 0 away from 41, we end up with 41.
Append the next digit (3) from the dividend to 41 and continue with: 413 / 72

Going ahead to step 5:
The number 72 fits into 413 5 times, leaving a remainder of 53.
Use 5 as the next digit of our solution. 
Result so far: 705.0
If we take 360 away from 413, we end up with 53.
Append the next digit (5) from the dividend to 53 and continue with: 535 / 72

Going ahead to step 6:
72 can be fit into 535 7 times, resulting in a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 7057.0
The remainder is 31 after subtracting 504 from 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
If we divide 310 by 72, we get 4 and a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 7057.4
Deduct 288 from 310 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
If we divide 220 by 72, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 7057.43
The remainder is 4 after subtracting 216 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
If we divide 40 by 72, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 7057.43
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
When dividing 400 by 72, we get 5 with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 7057.4305
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
400 divided by 72 is 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 7057.43055
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 7057.43055, and the remainder is 4e-05.
