912919 ÷ 72 
We want to figure out the number of times 912919 can be divided by 72.

Going ahead to step 1:
If we divide 9 by 72, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 72

Step 2:
72 can be fit into 91 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 72 from 91, we get 19.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 72

Moving on to step 3:
72 can be fit into 192 2 times, resulting in a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 144 away from 192, we end up with 48.
Include the next digit (9) from the dividend after 48, then repeat: 489 / 72

Advancing to step 4:
489 divided by 72 is 6 with a remainder of 57.
Use 6 as the next digit of our solution. 
Result so far: 126.0
Deduct 432 from 489 and we're left with 57.
Grab the next digit (1) from the dividend, add it to 57, then carry on: 571 / 72

On to step 5:
The number 72 fits into 571 7 times, leaving a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 1267.0
Subtract 504 from 571 to get 67.
Bring next digit (9) of the dividend behind the 67 and repeat the process: 679 / 72

Going ahead to step 6:
72 can be fit into 679 9 times, resulting in a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 12679.0
Subtracting 648 from 679 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
When dividing 310 by 72, we get 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 12679.4
Deduct 288 from 310 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
220 divided by 72 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 12679.43
Deduct 216 from 220 and we're left 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 9:
If we divide 40 by 72, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 12679.43
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.

Advancing to step 10:
When dividing 400 by 72, we get 5 with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 12679.4305
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.

Step 11:
The number 72 fits into 400 5 times, leaving a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 12679.43055
Deduct 360 from 400 and we're left 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.

After the division, we end up with 12679.43055 and a remainder of 4e-05.
