We divide 139488 by 72
We want to figure out the number of times 139488 can be divided by 72.

Advancing to step 1:
72 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 72

Going ahead to step 2:
When dividing 13 by 72, we get 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 72

Advancing to step 3:
139 divided by 72 is 1 with a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 72 from 139 leaves us with 67.
Append the next digit (4) from the dividend to 67 and continue with: 674 / 72

Advancing to step 4:
The number 72 fits into 674 9 times, leaving a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 26 after subtracting 648 from 674.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 72

Advancing to step 5:
72 can be fit into 268 3 times, resulting in a remainder of 52.
Put 3 as the next digit of the answer. 
Result so far: 193.0
Subtracting 216 from 268 leaves us with 52.
Include the next digit (8) from the dividend after 52, then repeat: 528 / 72

Going ahead to step 6:
528 divided by 72 is 7 with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 1937.0
If we subtract 504 from 528, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
240 divided by 72 is 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 1937.3
Deduct 216 from 240 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
When dividing 240 by 72, we get 3 with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 1937.33
The remainder is 24 after subtracting 216 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 1937.33, with a leftover of 0.024.
