We're dividing 831787 by 39 
Our goal is to divide 831787 by 39.

Step 1:
8 divided by 39 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 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.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 5 after subtracting 78 from 83.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 39

Let's proceed to step 3:
51 divided by 39 is 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtract 39 from 51 to get 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 39

Let's proceed to step 4:
The number 39 fits into 127 3 times, leaving a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 213.0
The remainder is 10 after subtracting 117 from 127.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 39

Advancing to step 5:
108 divided by 39 is 2 with a remainder of 30.
The next digit of our result is 2. 
Result so far: 2132.0
Deduct 78 from 108 and we're left with 30.
Take the next digit (7) from the dividend and append it to 30, then repeat: 307 / 39

Step 6:
The number 39 fits into 307 7 times, leaving a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 21327.0
Subtracting 273 from 307 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 7:
When dividing 340 by 39, we get 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 21327.8
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
280 divided by 39 is 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 21327.87
Deduct 273 from 280 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
39 can be fit into 70 1 times, resulting in a remainder of 31.
The next digit of our result is 1. 
Result so far: 21327.871
Subtract 39 from 70 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 10:
The number 39 fits into 310 7 times, leaving a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 21327.8717
Subtract 273 from 310 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 11:
When dividing 370 by 39, we get 9 with a remainder of 19.
The next digit of our result is 9. 
Result so far: 21327.87179
The remainder is 19 after subtracting 351 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 12:
39 goes into 190 4 times with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 21327.871794
If we subtract 156 from 190, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 13:
The number 39 fits into 340 8 times, leaving a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 21327.8717948
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 14:
280 divided by 39 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 21327.87179487
If we subtract 273 from 280, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 21327.87179487 with a balance of 7e-09.
