We divide 99686731 by 999
Let's see how many times 999 fits into 99686731.

Step 1:
The number 999 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 999

Going ahead to step 2:
When dividing 99 by 999, we get 0 with a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Grab the next digit (6) from the dividend, add it to 99, then carry on: 996 / 999

Let's proceed to step 3:
When dividing 996 by 999, we get 0 with a remainder of 996.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 996 to get 996.
Bring next digit (8) of the dividend behind the 996 and repeat the process: 9968 / 999

Step 4:
999 can be fit into 9968 9 times, resulting in a remainder of 977.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 8991 from 9968 and we're left with 977.
Take the next digit (6) from the dividend and append it to 977, then repeat: 9776 / 999

Let's proceed to step 5:
999 can be fit into 9776 9 times, resulting in a remainder of 785.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
If we subtract 8991 from 9776, we get 785.
Take the next digit (7) from the dividend and append it to 785, then repeat: 7857 / 999

On to step 6:
999 goes into 7857 7 times with a remainder of 864.
Write down 7 as next digit of the result. 
Result so far: 997.0
The remainder is 864 after subtracting 6993 from 7857.
Include the next digit (3) from the dividend after 864, then repeat: 8643 / 999

Moving on to step 7:
The number 999 fits into 8643 8 times, leaving a remainder of 651.
Record the quotient 8 as the next digit in the result. 
Result so far: 9978.0
Subtracting 7992 from 8643 leaves us with 651.
Append the next digit (1) from the dividend to 651 and continue with: 6511 / 999

Going ahead to step 8:
999 can be fit into 6511 6 times, resulting in a remainder of 517.
Record the quotient 6 as the next digit in the result. 
Result so far: 99786.0
Subtract 5994 from 6511 to get 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

On to step 9:
999 goes into 5170 5 times with a remainder of 175.
The next digit of our result is 5. 
Result so far: 99786.5
The remainder is 175 after subtracting 4995 from 5170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 10:
999 can be fit into 1750 1 times, resulting in a remainder of 751.
Write down 1 as next digit of the result. 
Result so far: 99786.51
If we take 999 away from 1750, we end up with 751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7510, and continue the process.

Going ahead to step 11:
The number 999 fits into 7510 7 times, leaving a remainder of 517.
Put 7 as the next digit of the answer. 
Result so far: 99786.517
If we take 6993 away from 7510, we end up with 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Step 12:
5170 divided by 999 is 5 with a remainder of 175.
The next digit of our result is 5. 
Result so far: 99786.5175
If we subtract 4995 from 5170, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 13:
If we divide 1750 by 999, we get 1 and a remainder of 751.
Record the quotient 1 as the next digit in the result. 
Result so far: 99786.51751
Subtracting 999 from 1750 leaves us with 751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7510, and continue the process.

Advancing to step 14:
999 goes into 7510 7 times with a remainder of 517.
The next digit of our result is 7. 
Result so far: 99786.517517
Deduct 6993 from 7510 and we're left with 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Going ahead to step 15:
When dividing 5170 by 999, we get 5 with a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 99786.5175175
If we subtract 4995 from 5170, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 16:
The number 999 fits into 1750 1 times, leaving a remainder of 751.
Write down 1 as next digit of the result. 
Result so far: 99786.51751751
Subtract 999 from 1750 to get 751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7510, and continue the process.

The final outcome is 99786.51751751, with a leftover of 7.51e-07.
