Let's divide 10571686 by 999
Our goal is to divide 10571686 by 999.

Let's proceed to step 1:
1 divided by 999 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 999

On to step 2:
The number 999 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 999

Step 3:
105 divided by 999 is 0 with a remainder of 105.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 105, we end up with 105.
Take the next digit (7) from the dividend and append it to 105, then repeat: 1057 / 999

Going ahead to step 4:
If we divide 1057 by 999, we get 1 and a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 999 from 1057 and we're left with 58.
Append the next digit (1) from the dividend to 58 and continue with: 581 / 999

Advancing to step 5:
If we divide 581 by 999, we get 0 and a remainder of 581.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 581 to get 581.
Bring next digit (6) of the dividend behind the 581 and repeat the process: 5816 / 999

Going ahead to step 6:
If we divide 5816 by 999, we get 5 and a remainder of 821.
Write down 5 as next digit of the result. 
Result so far: 105.0
The remainder is 821 after subtracting 4995 from 5816.
Grab the next digit (8) from the dividend, add it to 821, then carry on: 8218 / 999

Going ahead to step 7:
999 can be fit into 8218 8 times, resulting in a remainder of 226.
Use 8 as the next digit of our solution. 
Result so far: 1058.0
Subtract 7992 from 8218 to get 226.
Append the next digit (6) from the dividend to 226 and continue with: 2266 / 999

Moving on to step 8:
2266 divided by 999 is 2 with a remainder of 268.
Write down 2 as next digit of the result. 
Result so far: 10582.0
Deduct 1998 from 2266 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 9:
If we divide 2680 by 999, we get 2 and a remainder of 682.
The next digit of our result is 2. 
Result so far: 10582.2
If we subtract 1998 from 2680, we get 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Going ahead to step 10:
999 can be fit into 6820 6 times, resulting in a remainder of 826.
Use 6 as the next digit of our solution. 
Result so far: 10582.26
Subtract 5994 from 6820 to get 826.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8260, and continue the process.

Step 11:
8260 divided by 999 is 8 with a remainder of 268.
Use 8 as the next digit of our solution. 
Result so far: 10582.268
Subtracting 7992 from 8260 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 12:
999 goes into 2680 2 times with a remainder of 682.
Write down 2 as next digit of the result. 
Result so far: 10582.2682
If we take 1998 away from 2680, we end up with 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Advancing to step 13:
The number 999 fits into 6820 6 times, leaving a remainder of 826.
The next digit of our result is 6. 
Result so far: 10582.26826
Deduct 5994 from 6820 and we're left with 826.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8260, and continue the process.

Step 14:
If we divide 8260 by 999, we get 8 and a remainder of 268.
Write down 8 as next digit of the result. 
Result so far: 10582.268268
Subtract 7992 from 8260 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Step 15:
999 goes into 2680 2 times with a remainder of 682.
Record the quotient 2 as the next digit in the result. 
Result so far: 10582.2682682
Deduct 1998 from 2680 and we're left with 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Step 16:
When dividing 6820 by 999, we get 6 with a remainder of 826.
Put 6 as the next digit of the answer. 
Result so far: 10582.26826826
Deduct 5994 from 6820 and we're left with 826.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8260, and continue the process.

The final result is 10582.26826826 with a remainder of 8.26e-07.
