633891 divided by 72 
The aim is to understand the frequency of 72 in 633891.

On to step 1:
72 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 72

On to step 2:
The number 72 fits into 63 0 times, leaving a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Take the next digit (3) from the dividend and append it to 63, then repeat: 633 / 72

Moving on to step 3:
When dividing 633 by 72, we get 8 with a remainder of 57.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 576 from 633 and we're left with 57.
Append the next digit (8) from the dividend to 57 and continue with: 578 / 72

Moving on to step 4:
The number 72 fits into 578 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 88.0
Subtract 576 from 578 to get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 72

Moving on to step 5:
When dividing 29 by 72, we get 0 with a remainder of 29.
The next digit of our result is 0. 
Result so far: 880.0
Subtracting 0 from 29 leaves us with 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 72

On to step 6:
291 divided by 72 is 4 with a remainder of 3.
The next digit of our result is 4. 
Result so far: 8804.0
Deduct 288 from 291 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
72 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 8804.0
If we take 0 away from 30, we end up 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.

Going ahead to step 8:
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: 8804.04
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.

Let's proceed to step 9:
The number 72 fits into 120 1 times, leaving a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 8804.041
Subtract 72 from 120 to 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.

On to step 10:
The number 72 fits into 480 6 times, leaving a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 8804.0416
If we take 432 away from 480, we end up 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.

On to step 11:
If we divide 480 by 72, we get 6 and a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 8804.04166
Subtracting 432 from 480 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.

The quotient of the division is 8804.04166, and the remainder is 4.8e-05.
