We're dividing 13394 by 39 
We want to divide 13394 by 39.

Moving on to step 1:
1 divided by 39 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 39

On to step 2:
If we divide 13 by 39, we get 0 and a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 39

Let's proceed to step 3:
133 divided by 39 is 3 with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 117 away from 133, we end up with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 39

On to step 4:
When dividing 169 by 39, we get 4 with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtract 156 from 169 to get 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 39

Let's proceed to step 5:
134 divided by 39 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 343.0
If we take 117 away from 134, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 6:
When dividing 170 by 39, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 343.4
If we subtract 156 from 170, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
39 goes into 140 3 times with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 343.43
If we take 117 away from 140, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 8:
If we divide 230 by 39, we get 5 and a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 343.435
Subtracting 195 from 230 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
39 goes into 350 8 times with a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 343.4358
The remainder is 38 after subtracting 312 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
When dividing 380 by 39, we get 9 with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 343.43589
If we subtract 351 from 380, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 11:
39 goes into 290 7 times with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 343.435897
Deduct 273 from 290 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 12:
When dividing 170 by 39, we get 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 343.4358974
Subtracting 156 from 170 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
If we divide 140 by 39, we get 3 and a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 343.43589743
Subtracting 117 from 140 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Our division results in 343.43589743 with a remaining 2.3e-08.
