We look at the division of 10518991 by 665 
We want to divide 10518991 by 665.

Step 1:
If we divide 1 by 665, we get 0 and 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.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 665

Moving on to step 2:
665 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 665

Moving on to step 3:
If we divide 105 by 665, we get 0 and a remainder of 105.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 105, we end up with 105.
Bring next digit (1) of the dividend behind the 105 and repeat the process: 1051 / 665

Let's proceed to step 4:
The number 665 fits into 1051 1 times, leaving a remainder of 386.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 665 from 1051, we get 386.
Take the next digit (8) from the dividend and append it to 386, then repeat: 3868 / 665

Going ahead to step 5:
665 can be fit into 3868 5 times, resulting in a remainder of 543.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 3325 from 3868 leaves us with 543.
Append the next digit (9) from the dividend to 543 and continue with: 5439 / 665

On to step 6:
665 goes into 5439 8 times with a remainder of 119.
The next digit of our result is 8. 
Result so far: 158.0
Deduct 5320 from 5439 and we're left with 119.
Take the next digit (9) from the dividend and append it to 119, then repeat: 1199 / 665

On to step 7:
665 can be fit into 1199 1 times, resulting in a remainder of 534.
Use 1 as the next digit of our solution. 
Result so far: 1581.0
Subtracting 665 from 1199 leaves us with 534.
Bring next digit (1) of the dividend behind the 534 and repeat the process: 5341 / 665

Going ahead to step 8:
When dividing 5341 by 665, we get 8 with a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 15818.0
The remainder is 21 after subtracting 5320 from 5341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 9:
665 goes into 210 0 times with a remainder of 210.
The next digit of our result is 0. 
Result so far: 15818.0
If we subtract 0 from 210, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 10:
The number 665 fits into 2100 3 times, leaving a remainder of 105.
Write down 3 as next digit of the result. 
Result so far: 15818.03
Subtract 1995 from 2100 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 11:
665 goes into 1050 1 times with a remainder of 385.
Write down 1 as next digit of the result. 
Result so far: 15818.031
Deduct 665 from 1050 and we're left with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

On to step 12:
665 goes into 3850 5 times with a remainder of 525.
Use 5 as the next digit of our solution. 
Result so far: 15818.0315
Subtract 3325 from 3850 to get 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Moving on to step 13:
665 can be fit into 5250 7 times, resulting in a remainder of 595.
The next digit of our result is 7. 
Result so far: 15818.03157
The remainder is 595 after subtracting 4655 from 5250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Moving on to step 14:
When dividing 5950 by 665, we get 8 with a remainder of 630.
Use 8 as the next digit of our solution. 
Result so far: 15818.031578
Subtract 5320 from 5950 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

On to step 15:
665 goes into 6300 9 times with a remainder of 315.
Record the quotient 9 as the next digit in the result. 
Result so far: 15818.0315789
If we take 5985 away from 6300, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Let's proceed to step 16:
3150 divided by 665 is 4 with a remainder of 490.
Record the quotient 4 as the next digit in the result. 
Result so far: 15818.03157894
The remainder is 490 after subtracting 2660 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

The quotient of the division is 15818.03157894, and the remainder is 4.9e-07.
