We look at the division of 17939109 by 655 
We want to divide 17939109 by 655.

On to step 1:
655 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 655

Moving on to step 2:
17 divided by 655 is 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 655

Moving on to step 3:
179 divided by 655 is 0 with a remainder of 179.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 179 to get 179.
Take the next digit (3) from the dividend and append it to 179, then repeat: 1793 / 655

Moving on to step 4:
When dividing 1793 by 655, we get 2 with a remainder of 483.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1310 away from 1793, we end up with 483.
Grab the next digit (9) from the dividend, add it to 483, then carry on: 4839 / 655

Step 5:
655 can be fit into 4839 7 times, resulting in a remainder of 254.
Write down 7 as next digit of the result. 
Result so far: 27.0
Deduct 4585 from 4839 and we're left with 254.
Bring next digit (1) of the dividend behind the 254 and repeat the process: 2541 / 655

Advancing to step 6:
2541 divided by 655 is 3 with a remainder of 576.
Record the quotient 3 as the next digit in the result. 
Result so far: 273.0
The remainder is 576 after subtracting 1965 from 2541.
Grab the next digit (0) from the dividend, add it to 576, then carry on: 5760 / 655

Moving on to step 7:
5760 divided by 655 is 8 with a remainder of 520.
Put 8 as the next digit of the answer. 
Result so far: 2738.0
Subtracting 5240 from 5760 leaves us with 520.
Fetch the next digit (9) from the dividend, attach it to 520 and continue: 5209 / 655

Advancing to step 8:
When dividing 5209 by 655, we get 7 with a remainder of 624.
Put 7 as the next digit of the answer. 
Result so far: 27387.0
The remainder is 624 after subtracting 4585 from 5209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Let's proceed to step 9:
655 can be fit into 6240 9 times, resulting in a remainder of 345.
Record the quotient 9 as the next digit in the result. 
Result so far: 27387.9
If we subtract 5895 from 6240, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Going ahead to step 10:
When dividing 3450 by 655, we get 5 with a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 27387.95
Deduct 3275 from 3450 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 11:
1750 divided by 655 is 2 with a remainder of 440.
The next digit of our result is 2. 
Result so far: 27387.952
Subtracting 1310 from 1750 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 12:
655 goes into 4400 6 times with a remainder of 470.
Put 6 as the next digit of the answer. 
Result so far: 27387.9526
If we take 3930 away from 4400, we end up with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

On to step 13:
4700 divided by 655 is 7 with a remainder of 115.
Use 7 as the next digit of our solution. 
Result so far: 27387.95267
Deduct 4585 from 4700 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 14:
When dividing 1150 by 655, we get 1 with a remainder of 495.
The number 1 becomes the next digit in our result. 
Result so far: 27387.952671
If we subtract 655 from 1150, we get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Step 15:
When dividing 4950 by 655, we get 7 with a remainder of 365.
The number 7 becomes the next digit in our result. 
Result so far: 27387.9526717
The remainder is 365 after subtracting 4585 from 4950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Going ahead to step 16:
3650 divided by 655 is 5 with a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 27387.95267175
Deduct 3275 from 3650 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

The final result is 27387.95267175 with a remainder of 3.75e-07.
