We divide 125148 by 72
The aim is to understand the frequency of 72 in 125148.

On to step 1:
If we divide 1 by 72, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 72

On to step 2:
12 divided by 72 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 72

Let's proceed to step 3:
The number 72 fits into 125 1 times, leaving a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 53 after subtracting 72 from 125.
Append the next digit (1) from the dividend to 53 and continue with: 531 / 72

Going ahead to step 4:
If we divide 531 by 72, we get 7 and a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 504 from 531, we get 27.
Take the next digit (4) from the dividend and append it to 27, then repeat: 274 / 72

Let's proceed to step 5:
If we divide 274 by 72, we get 3 and a remainder of 58.
The number 3 becomes the next digit in our result. 
Result so far: 173.0
If we subtract 216 from 274, we get 58.
Fetch the next digit (8) from the dividend, attach it to 58 and continue: 588 / 72

On to step 6:
The number 72 fits into 588 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 1738.0
Deduct 576 from 588 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 7:
When dividing 120 by 72, we get 1 with a remainder of 48.
Use 1 as the next digit of our solution. 
Result so far: 1738.1
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.

Going ahead to step 8:
If we divide 480 by 72, we get 6 and a remainder of 48.
The next digit of our result is 6. 
Result so far: 1738.16
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.

Moving on to step 9:
The number 72 fits into 480 6 times, leaving a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 1738.166
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.

The final outcome is 1738.166, with a leftover of 0.0048.
