590408 divided by 72 
The aim is to understand the frequency of 72 in 590408.

On to step 1:
72 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 72

Step 2:
59 divided by 72 is 0 with a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 59 to get 59.
Grab the next digit (0) from the dividend, add it to 59, then carry on: 590 / 72

Let's proceed to step 3:
590 divided by 72 is 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 576 from 590, we get 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 72

Advancing to step 4:
The number 72 fits into 144 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 82.0
If we subtract 144 from 144, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 72

Going ahead to step 5:
72 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 820.0
If we take 0 away from 0, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 72

Step 6:
8 divided by 72 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 8200.0
If we take 0 away from 8, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
The number 72 fits into 80 1 times, leaving a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 8200.1
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
If we divide 80 by 72, we get 1 and a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 8200.11
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 8200.11, with a leftover of 0.008.
