We divide 628662 by 72
The aim is to understand the frequency of 72 in 628662.

Going ahead to step 1:
When dividing 6 by 72, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 72

Advancing to step 2:
72 can be fit into 62 0 times, resulting in a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Bring next digit (8) of the dividend behind the 62 and repeat the process: 628 / 72

Let's proceed to step 3:
When dividing 628 by 72, we get 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 52 after subtracting 576 from 628.
Grab the next digit (6) from the dividend, add it to 52, then carry on: 526 / 72

Let's proceed to step 4:
72 can be fit into 526 7 times, resulting in a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 87.0
If we subtract 504 from 526, we get 22.
Fetch the next digit (6) from the dividend, attach it to 22 and continue: 226 / 72

Going ahead to step 5:
The number 72 fits into 226 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 873.0
If we subtract 216 from 226, we get 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 72

On to step 6:
102 divided by 72 is 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 8731.0
Deduct 72 from 102 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
When dividing 300 by 72, we get 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 8731.4
Deduct 288 from 300 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
When dividing 120 by 72, we get 1 with a remainder of 48.
The next digit of our result is 1. 
Result so far: 8731.41
Subtracting 72 from 120 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 9:
72 can be fit into 480 6 times, resulting in a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 8731.416
If we subtract 432 from 480, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
If we divide 480 by 72, we get 6 and a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 8731.4166
The remainder is 48 after subtracting 432 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 8731.4166 and a remainder of 0.00048.
