526720 divided by 72 
The aim is to understand the frequency of 72 in 526720.

On to step 1:
If we divide 5 by 72, we get 0 and 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 (2) from the dividend, add it to 5, then carry on: 52 / 72

On to step 2:
The number 72 fits into 52 0 times, leaving a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Fetch the next digit (6) from the dividend, attach it to 52 and continue: 526 / 72

On to step 3:
When dividing 526 by 72, we get 7 with a remainder of 22.
The next digit of our result is 7. 
Result so far: 7.0
If we take 504 away from 526, we end up with 22.
Grab the next digit (7) from the dividend, add it to 22, then carry on: 227 / 72

Advancing to step 4:
The number 72 fits into 227 3 times, leaving a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 73.0
Deduct 216 from 227 and we're left with 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 72

On to step 5:
72 goes into 112 1 times with a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 731.0
Subtracting 72 from 112 leaves us with 40.
Include the next digit (0) from the dividend after 40, then repeat: 400 / 72

Let's proceed to step 6:
If we divide 400 by 72, we get 5 and a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 7315.0
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
72 can be fit into 400 5 times, resulting in a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 7315.5
The remainder is 40 after subtracting 360 from 400.
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 8:
If we divide 400 by 72, we get 5 and a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 7315.55
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 7315.55, and the remainder is 0.04.
