We look at the division of 123665 by 72 
We want to figure out the number of times 123665 can be divided by 72.

Moving on to step 1:
If we divide 1 by 72, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 72

Step 2:
72 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 72

Advancing to step 3:
72 goes into 123 1 times with a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 72 from 123 and we're left with 51.
Bring next digit (6) of the dividend behind the 51 and repeat the process: 516 / 72

Step 4:
516 divided by 72 is 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 504 away from 516, we end up with 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 72

On to step 5:
When dividing 126 by 72, we get 1 with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 171.0
If we take 72 away from 126, we end up with 54.
Grab the next digit (5) from the dividend, add it to 54, then carry on: 545 / 72

On to step 6:
545 divided by 72 is 7 with a remainder of 41.
The next digit of our result is 7. 
Result so far: 1717.0
The remainder is 41 after subtracting 504 from 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
72 can be fit into 410 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 1717.5
The remainder is 50 after subtracting 360 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
The number 72 fits into 500 6 times, leaving a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 1717.56
The remainder is 68 after subtracting 432 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
72 goes into 680 9 times with a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 1717.569
Subtracting 648 from 680 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
The number 72 fits into 320 4 times, leaving a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 1717.5694
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
320 divided by 72 is 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 1717.56944
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 1717.56944, and the remainder is 3.2e-05.
