We look at the division of 831495 by 39 
Our goal is to divide 831495 by 39.

Step 1:
39 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 39

Going ahead to step 2:
The number 39 fits into 83 2 times, leaving a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 5 after subtracting 78 from 83.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 39

Step 3:
39 goes into 51 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 39 from 51, we get 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 39

Step 4:
124 divided by 39 is 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 213.0
Subtracting 117 from 124 leaves us with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 39

Advancing to step 5:
39 can be fit into 79 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2132.0
If we subtract 78 from 79, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 39

Advancing to step 6:
15 divided by 39 is 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 21320.0
Deduct 0 from 15 and we're left 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 7:
The number 39 fits into 150 3 times, leaving a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 21320.3
Subtract 117 from 150 to 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 8:
330 divided by 39 is 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 21320.38
Subtracting 312 from 330 leaves us 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.

Moving on to step 9:
The number 39 fits into 180 4 times, leaving a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 21320.384
If we subtract 156 from 180, we 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.

Moving on to step 10:
The number 39 fits into 240 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 21320.3846
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.

Moving on to step 11:
39 goes into 60 1 times with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 21320.38461
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.

On to step 12:
39 goes into 210 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 21320.384615
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.

Moving on to step 13:
If we divide 150 by 39, we get 3 and a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 21320.3846153
Deduct 117 from 150 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 14:
The number 39 fits into 330 8 times, leaving a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 21320.38461538
The remainder is 18 after subtracting 312 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 21320.38461538, with a leftover of 1.8e-08.
