72689914 ÷ 999 
We want to figure out the number of times 72689914 can be divided by 999.

On to step 1:
If we divide 7 by 999, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 999

Moving on to step 2:
999 goes into 72 0 times with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Grab the next digit (6) from the dividend, add it to 72, then carry on: 726 / 999

Step 3:
999 can be fit into 726 0 times, resulting in a remainder of 726.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 726, we get 726.
Fetch the next digit (8) from the dividend, attach it to 726 and continue: 7268 / 999

Moving on to step 4:
When dividing 7268 by 999, we get 7 with a remainder of 275.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 6993 from 7268 leaves us with 275.
Take the next digit (9) from the dividend and append it to 275, then repeat: 2759 / 999

Advancing to step 5:
2759 divided by 999 is 2 with a remainder of 761.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
If we take 1998 away from 2759, we end up with 761.
Take the next digit (9) from the dividend and append it to 761, then repeat: 7619 / 999

Let's proceed to step 6:
999 can be fit into 7619 7 times, resulting in a remainder of 626.
Use 7 as the next digit of our solution. 
Result so far: 727.0
If we subtract 6993 from 7619, we get 626.
Take the next digit (1) from the dividend and append it to 626, then repeat: 6261 / 999

Going ahead to step 7:
999 goes into 6261 6 times with a remainder of 267.
Put 6 as the next digit of the answer. 
Result so far: 7276.0
If we take 5994 away from 6261, we end up with 267.
Fetch the next digit (4) from the dividend, attach it to 267 and continue: 2674 / 999

Moving on to step 8:
999 can be fit into 2674 2 times, resulting in a remainder of 676.
The next digit of our result is 2. 
Result so far: 72762.0
Deduct 1998 from 2674 and we're left with 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Step 9:
The number 999 fits into 6760 6 times, leaving a remainder of 766.
The next digit of our result is 6. 
Result so far: 72762.6
Subtract 5994 from 6760 to get 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

On to step 10:
The number 999 fits into 7660 7 times, leaving a remainder of 667.
Record the quotient 7 as the next digit in the result. 
Result so far: 72762.67
Deduct 6993 from 7660 and we're left with 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

On to step 11:
If we divide 6670 by 999, we get 6 and a remainder of 676.
The next digit of our result is 6. 
Result so far: 72762.676
Subtracting 5994 from 6670 leaves us with 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Moving on to step 12:
When dividing 6760 by 999, we get 6 with a remainder of 766.
Record the quotient 6 as the next digit in the result. 
Result so far: 72762.6766
Deduct 5994 from 6760 and we're left with 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

Our division results in 72762.6766 with a remaining 0.00766.
