We divide 931612 by 72
The aim is to understand the frequency of 72 in 931612.

On to step 1:
When dividing 9 by 72, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 72

Let's proceed to step 2:
93 divided by 72 is 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 72 from 93, we get 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 72

On to step 3:
The number 72 fits into 211 2 times, leaving a remainder of 67.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 67 after subtracting 144 from 211.
Append the next digit (6) from the dividend to 67 and continue with: 676 / 72

Let's proceed to step 4:
The number 72 fits into 676 9 times, leaving a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 129.0
Subtract 648 from 676 to get 28.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 72

Step 5:
When dividing 281 by 72, we get 3 with a remainder of 65.
The next digit of our result is 3. 
Result so far: 1293.0
If we take 216 away from 281, we end up with 65.
Append the next digit (2) from the dividend to 65 and continue with: 652 / 72

On to step 6:
When dividing 652 by 72, we get 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 12939.0
Subtracting 648 from 652 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
When dividing 40 by 72, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 12939.0
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.

Moving on to step 8:
If we divide 400 by 72, we get 5 and a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 12939.05
Subtracting 360 from 400 leaves us 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.

On to step 9:
72 can be fit into 400 5 times, resulting in a remainder of 40.
The next digit of our result is 5. 
Result so far: 12939.055
If we subtract 360 from 400, we 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.

In conclusion, the division gives 12939.055 with a balance of 0.004.
