Let's divide 10205350 by 831
Our goal is to divide 10205350 by 831.

Step 1:
If we divide 1 by 831, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 831

Step 2:
831 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 831

Step 3:
If we divide 102 by 831, we get 0 and a remainder of 102.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 102 and we're left with 102.
Bring next digit (0) of the dividend behind the 102 and repeat the process: 1020 / 831

Let's proceed to step 4:
The number 831 fits into 1020 1 times, leaving a remainder of 189.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 831 from 1020 leaves us with 189.
Fetch the next digit (5) from the dividend, attach it to 189 and continue: 1895 / 831

Let's proceed to step 5:
The number 831 fits into 1895 2 times, leaving a remainder of 233.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 1662 from 1895 and we're left with 233.
Take the next digit (3) from the dividend and append it to 233, then repeat: 2333 / 831

On to step 6:
2333 divided by 831 is 2 with a remainder of 671.
Write down 2 as next digit of the result. 
Result so far: 122.0
If we take 1662 away from 2333, we end up with 671.
Take the next digit (5) from the dividend and append it to 671, then repeat: 6715 / 831

Moving on to step 7:
When dividing 6715 by 831, we get 8 with a remainder of 67.
Write down 8 as next digit of the result. 
Result so far: 1228.0
Subtract 6648 from 6715 to get 67.
Grab the next digit (0) from the dividend, add it to 67, then carry on: 670 / 831

Going ahead to step 8:
If we divide 670 by 831, we get 0 and a remainder of 670.
Put 0 as the next digit of the answer. 
Result so far: 12280.0
The remainder is 670 after subtracting 0 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Step 9:
When dividing 6700 by 831, we get 8 with a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 12280.8
If we subtract 6648 from 6700, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
831 can be fit into 520 0 times, resulting in a remainder of 520.
The number 0 becomes the next digit in our result. 
Result so far: 12280.8
Subtract 0 from 520 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 11:
5200 divided by 831 is 6 with a remainder of 214.
The next digit of our result is 6. 
Result so far: 12280.806
The remainder is 214 after subtracting 4986 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 12:
2140 divided by 831 is 2 with a remainder of 478.
The number 2 becomes the next digit in our result. 
Result so far: 12280.8062
Subtracting 1662 from 2140 leaves us with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Step 13:
4780 divided by 831 is 5 with a remainder of 625.
Use 5 as the next digit of our solution. 
Result so far: 12280.80625
Subtracting 4155 from 4780 leaves us with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Advancing to step 14:
When dividing 6250 by 831, we get 7 with a remainder of 433.
Put 7 as the next digit of the answer. 
Result so far: 12280.806257
The remainder is 433 after subtracting 5817 from 6250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Step 15:
831 goes into 4330 5 times with a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 12280.8062575
The remainder is 175 after subtracting 4155 from 4330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 16:
1750 divided by 831 is 2 with a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 12280.80625752
If we subtract 1662 from 1750, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

In conclusion, the division gives 12280.80625752 with a balance of 8.8e-08.
