393124 ÷ 13 
Let's see how many times 13 fits into 393124.

Advancing to step 1:
3 divided by 13 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 13

Moving on to step 2:
13 goes into 39 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 39 away from 39, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 13

Advancing to step 3:
3 divided by 13 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 13

On to step 4:
When dividing 31 by 13, we get 2 with a remainder of 5.
The next digit of our result is 2. 
Result so far: 302.0
Subtracting 26 from 31 leaves us with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 13

Going ahead to step 5:
13 goes into 52 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 3024.0
Subtract 52 from 52 to get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 13

On to step 6:
4 divided by 13 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 30240.0
The remainder is 4 after subtracting 0 from 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
If we divide 40 by 13, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 30240.3
If we take 39 away from 40, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
When dividing 10 by 13, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 30240.3
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
If we divide 100 by 13, we get 7 and a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 30240.307
The remainder is 9 after subtracting 91 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 10:
If we divide 90 by 13, we get 6 and a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 30240.3076
Subtract 78 from 90 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
If we divide 120 by 13, we get 9 and a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 30240.30769
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 12:
13 can be fit into 30 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 30240.307692
If we subtract 26 from 30, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
13 can be fit into 40 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 30240.3076923
Subtracting 39 from 40 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 14:
The number 13 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 30240.3076923
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 30240.3076923, and the remainder is 1e-08.
