We look at the division of 757 by 39 
Let's see how many times 39 fits into 757.

Advancing to step 1:
When dividing 7 by 39, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 39

Moving on to step 2:
If we divide 75 by 39, we get 1 and a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 39 away from 75, we end up with 36.
Bring next digit (7) of the dividend behind the 36 and repeat the process: 367 / 39

Going ahead to step 3:
When dividing 367 by 39, we get 9 with a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 16 after subtracting 351 from 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 4:
The number 39 fits into 160 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 19.4
If we subtract 156 from 160, 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 5:
When dividing 40 by 39, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 19.41
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.

Let's proceed to step 6:
When dividing 10 by 39, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 19.41
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.

Moving on to step 7:
If we divide 100 by 39, we get 2 and a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 19.4102
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
39 can be fit into 220 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 19.41025
If we take 195 away from 220, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
When dividing 250 by 39, we get 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 19.410256
The remainder is 16 after subtracting 234 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
The number 39 fits into 160 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 19.4102564
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
The number 39 fits into 40 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 19.41025641
Deduct 39 from 40 and we're left 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.

The final outcome is 19.41025641, with a leftover of 1e-09.
