13200813 ÷ 424 
We want to divide 13200813 by 424.

Advancing to step 1:
When dividing 1 by 424, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 424

Advancing to step 2:
424 goes into 13 0 times with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 424

Moving on to step 3:
424 goes into 132 0 times with a remainder of 132.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 132 and we're left with 132.
Append the next digit (0) from the dividend to 132 and continue with: 1320 / 424

Step 4:
When dividing 1320 by 424, we get 3 with a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 1272 from 1320, we get 48.
Fetch the next digit (0) from the dividend, attach it to 48 and continue: 480 / 424

Step 5:
When dividing 480 by 424, we get 1 with a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtract 424 from 480 to get 56.
Grab the next digit (8) from the dividend, add it to 56, then carry on: 568 / 424

Step 6:
568 divided by 424 is 1 with a remainder of 144.
Use 1 as the next digit of our solution. 
Result so far: 311.0
Deduct 424 from 568 and we're left with 144.
Append the next digit (1) from the dividend to 144 and continue with: 1441 / 424

Going ahead to step 7:
424 goes into 1441 3 times with a remainder of 169.
Record the quotient 3 as the next digit in the result. 
Result so far: 3113.0
Deduct 1272 from 1441 and we're left with 169.
Include the next digit (3) from the dividend after 169, then repeat: 1693 / 424

On to step 8:
The number 424 fits into 1693 3 times, leaving a remainder of 421.
Write down 3 as next digit of the result. 
Result so far: 31133.0
If we take 1272 away from 1693, we end up with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Advancing to step 9:
If we divide 4210 by 424, we get 9 and a remainder of 394.
Put 9 as the next digit of the answer. 
Result so far: 31133.9
Subtract 3816 from 4210 to get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Step 10:
When dividing 3940 by 424, we get 9 with a remainder of 124.
The next digit of our result is 9. 
Result so far: 31133.99
Subtract 3816 from 3940 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Our division results in 31133.99 with a remaining 0.124.
