We look at the division of 17996983 by 660 
Let's see how many times 660 fits into 17996983.

Let's proceed to step 1:
When dividing 1 by 660, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 660

Step 2:
If we divide 17 by 660, we get 0 and a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 660

Let's proceed to step 3:
660 goes into 179 0 times with a remainder of 179.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 179 after subtracting 0 from 179.
Bring next digit (9) of the dividend behind the 179 and repeat the process: 1799 / 660

On to step 4:
If we divide 1799 by 660, we get 2 and a remainder of 479.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 479 after subtracting 1320 from 1799.
Bring next digit (6) of the dividend behind the 479 and repeat the process: 4796 / 660

Moving on to step 5:
When dividing 4796 by 660, we get 7 with a remainder of 176.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtracting 4620 from 4796 leaves us with 176.
Append the next digit (9) from the dividend to 176 and continue with: 1769 / 660

Going ahead to step 6:
If we divide 1769 by 660, we get 2 and a remainder of 449.
Use 2 as the next digit of our solution. 
Result so far: 272.0
Subtracting 1320 from 1769 leaves us with 449.
Grab the next digit (8) from the dividend, add it to 449, then carry on: 4498 / 660

Moving on to step 7:
660 goes into 4498 6 times with a remainder of 538.
Put 6 as the next digit of the answer. 
Result so far: 2726.0
If we subtract 3960 from 4498, we get 538.
Fetch the next digit (3) from the dividend, attach it to 538 and continue: 5383 / 660

Moving on to step 8:
5383 divided by 660 is 8 with a remainder of 103.
The number 8 becomes the next digit in our result. 
Result so far: 27268.0
Subtract 5280 from 5383 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Going ahead to step 9:
660 can be fit into 1030 1 times, resulting in a remainder of 370.
Write down 1 as next digit of the result. 
Result so far: 27268.1
The remainder is 370 after subtracting 660 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 10:
When dividing 3700 by 660, we get 5 with a remainder of 400.
Put 5 as the next digit of the answer. 
Result so far: 27268.15
If we subtract 3300 from 3700, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 11:
When dividing 4000 by 660, we get 6 with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 27268.156
Deduct 3960 from 4000 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
400 divided by 660 is 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 27268.156
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
660 goes into 4000 6 times with a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 27268.15606
If we take 3960 away from 4000, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
The number 660 fits into 400 0 times, leaving a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 27268.15606
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 15:
The number 660 fits into 4000 6 times, leaving a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 27268.1560606
Subtracting 3960 from 4000 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 16:
400 divided by 660 is 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 27268.1560606
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 27268.1560606, with a leftover of 4e-07.
