We're dividing 13299520 by 665 
We want to divide 13299520 by 665.

Going ahead to step 1:
665 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 665

On to step 2:
If we divide 13 by 665, we get 0 and a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 665

Let's proceed to step 3:
The number 665 fits into 132 0 times, leaving a remainder of 132.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 132, we get 132.
Grab the next digit (9) from the dividend, add it to 132, then carry on: 1329 / 665

On to step 4:
When dividing 1329 by 665, we get 1 with a remainder of 664.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 665 from 1329 leaves us with 664.
Bring next digit (9) of the dividend behind the 664 and repeat the process: 6649 / 665

Moving on to step 5:
When dividing 6649 by 665, we get 9 with a remainder of 664.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 664 after subtracting 5985 from 6649.
Bring next digit (5) of the dividend behind the 664 and repeat the process: 6645 / 665

Step 6:
6645 divided by 665 is 9 with a remainder of 660.
Use 9 as the next digit of our solution. 
Result so far: 199.0
Deduct 5985 from 6645 and we're left with 660.
Grab the next digit (2) from the dividend, add it to 660, then carry on: 6602 / 665

Advancing to step 7:
If we divide 6602 by 665, we get 9 and a remainder of 617.
Use 9 as the next digit of our solution. 
Result so far: 1999.0
If we subtract 5985 from 6602, we get 617.
Fetch the next digit (0) from the dividend, attach it to 617 and continue: 6170 / 665

Moving on to step 8:
6170 divided by 665 is 9 with a remainder of 185.
The number 9 becomes the next digit in our result. 
Result so far: 19999.0
Subtracting 5985 from 6170 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 9:
When dividing 1850 by 665, we get 2 with a remainder of 520.
The number 2 becomes the next digit in our result. 
Result so far: 19999.2
Subtract 1330 from 1850 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 10:
The number 665 fits into 5200 7 times, leaving a remainder of 545.
The number 7 becomes the next digit in our result. 
Result so far: 19999.27
If we take 4655 away from 5200, we end up with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Step 11:
When dividing 5450 by 665, we get 8 with a remainder of 130.
Put 8 as the next digit of the answer. 
Result so far: 19999.278
The remainder is 130 after subtracting 5320 from 5450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 12:
When dividing 1300 by 665, we get 1 with a remainder of 635.
Use 1 as the next digit of our solution. 
Result so far: 19999.2781
If we take 665 away from 1300, we end up with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Moving on to step 13:
665 can be fit into 6350 9 times, resulting in a remainder of 365.
Write down 9 as next digit of the result. 
Result so far: 19999.27819
If we take 5985 away from 6350, we end up with 365.
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 14:
3650 divided by 665 is 5 with a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 19999.278195
Subtract 3325 from 3650 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 15:
When dividing 3250 by 665, we get 4 with a remainder of 590.
Put 4 as the next digit of the answer. 
Result so far: 19999.2781954
If we take 2660 away from 3250, we end up with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 16:
The number 665 fits into 5900 8 times, leaving a remainder of 580.
Use 8 as the next digit of our solution. 
Result so far: 19999.27819548
If we take 5320 away from 5900, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

The final result is 19999.27819548 with a remainder of 5.8e-07.
