We look at the division of 8879720 by 999 
We want to divide 8879720 by 999.

On to step 1:
999 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 999

Advancing to step 2:
The number 999 fits into 88 0 times, leaving a remainder of 88.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 88 after subtracting 0 from 88.
Fetch the next digit (7) from the dividend, attach it to 88 and continue: 887 / 999

On to step 3:
If we divide 887 by 999, we get 0 and a remainder of 887.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 887 after subtracting 0 from 887.
Include the next digit (9) from the dividend after 887, then repeat: 8879 / 999

On to step 4:
When dividing 8879 by 999, we get 8 with a remainder of 887.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 7992 from 8879 and we're left with 887.
Take the next digit (7) from the dividend and append it to 887, then repeat: 8877 / 999

Step 5:
When dividing 8877 by 999, we get 8 with a remainder of 885.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
Subtract 7992 from 8877 to get 885.
Grab the next digit (2) from the dividend, add it to 885, then carry on: 8852 / 999

Step 6:
999 goes into 8852 8 times with a remainder of 860.
Record the quotient 8 as the next digit in the result. 
Result so far: 888.0
If we take 7992 away from 8852, we end up with 860.
Bring next digit (0) of the dividend behind the 860 and repeat the process: 8600 / 999

Advancing to step 7:
When dividing 8600 by 999, we get 8 with a remainder of 608.
The next digit of our result is 8. 
Result so far: 8888.0
Deduct 7992 from 8600 and we're left with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Step 8:
If we divide 6080 by 999, we get 6 and a remainder of 86.
The next digit of our result is 6. 
Result so far: 8888.6
If we take 5994 away from 6080, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 9:
860 divided by 999 is 0 with a remainder of 860.
Use 0 as the next digit of our solution. 
Result so far: 8888.6
If we take 0 away from 860, we end up with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

On to step 10:
The number 999 fits into 8600 8 times, leaving a remainder of 608.
Write down 8 as next digit of the result. 
Result so far: 8888.608
The remainder is 608 after subtracting 7992 from 8600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Moving on to step 11:
When dividing 6080 by 999, we get 6 with a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 8888.6086
Deduct 5994 from 6080 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 12:
999 can be fit into 860 0 times, resulting in a remainder of 860.
Write down 0 as next digit of the result. 
Result so far: 8888.6086
If we take 0 away from 860, we end up with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Going ahead to step 13:
999 can be fit into 8600 8 times, resulting in a remainder of 608.
Write down 8 as next digit of the result. 
Result so far: 8888.608608
The remainder is 608 after subtracting 7992 from 8600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Moving on to step 14:
If we divide 6080 by 999, we get 6 and a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 8888.6086086
Subtract 5994 from 6080 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 15:
860 divided by 999 is 0 with a remainder of 860.
Record the quotient 0 as the next digit in the result. 
Result so far: 8888.6086086
Subtract 0 from 860 to get 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.
