We're dividing 456012 by 39 
We want to divide 456012 by 39.

On to step 1:
39 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 39

On to step 2:
The number 39 fits into 45 1 times, leaving a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 39 from 45 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 39

Advancing to step 3:
If we divide 66 by 39, we get 1 and a remainder of 27.
The next digit of our result is 1. 
Result so far: 11.0
If we take 39 away from 66, we end up with 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 39

Going ahead to step 4:
39 goes into 270 6 times with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
Deduct 234 from 270 and we're left with 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 39

Advancing to step 5:
If we divide 361 by 39, we get 9 and a remainder of 10.
The next digit of our result is 9. 
Result so far: 1169.0
If we subtract 351 from 361, we get 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 39

Let's proceed to step 6:
The number 39 fits into 102 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 11692.0
Subtract 78 from 102 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
If we divide 240 by 39, we get 6 and a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 11692.6
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
When dividing 60 by 39, we get 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 11692.61
The remainder is 21 after subtracting 39 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 9:
When dividing 210 by 39, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 11692.615
If we take 195 away from 210, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
39 goes into 150 3 times with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 11692.6153
If we subtract 117 from 150, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 11:
39 can be fit into 330 8 times, resulting in a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 11692.61538
If we take 312 away from 330, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
When dividing 180 by 39, we get 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 11692.615384
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
39 goes into 240 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 11692.6153846
If we take 234 away from 240, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
39 can be fit into 60 1 times, resulting in a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 11692.61538461
Subtracting 39 from 60 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 11692.61538461, with a leftover of 2.1e-08.
