We divide 831431 by 39
Our goal is to divide 831431 by 39.

On to step 1:
39 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 39

Moving on to step 2:
83 divided by 39 is 2 with a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
If we take 78 away from 83, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 39

Advancing to step 3:
51 divided by 39 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 21.0
Deduct 39 from 51 and we're left with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 39

Advancing to step 4:
39 can be fit into 124 3 times, resulting in a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 213.0
If we take 117 away from 124, we end up with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 39

Going ahead to step 5:
If we divide 73 by 39, we get 1 and a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 2131.0
Deduct 39 from 73 and we're left with 34.
Bring next digit (1) of the dividend behind the 34 and repeat the process: 341 / 39

Step 6:
When dividing 341 by 39, we get 8 with a remainder of 29.
The next digit of our result is 8. 
Result so far: 21318.0
Subtract 312 from 341 to 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.

Going ahead to step 7:
290 divided by 39 is 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 21318.7
Subtract 273 from 290 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 8:
170 divided by 39 is 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 21318.74
If we take 156 away from 170, we end up 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.

Moving on to step 9:
The number 39 fits into 140 3 times, leaving a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 21318.743
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.

Going ahead to step 10:
39 can be fit into 230 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 21318.7435
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 11:
350 divided by 39 is 8 with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 21318.74358
Deduct 312 from 350 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
380 divided by 39 is 9 with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 21318.743589
Subtracting 351 from 380 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 13:
290 divided by 39 is 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 21318.7435897
If we take 273 away from 290, 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.

Advancing to step 14:
The number 39 fits into 170 4 times, leaving a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 21318.74358974
The remainder is 14 after subtracting 156 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 21318.74358974 with a balance of 1.4e-08.
