We divide 3459342 by 831
We want to figure out the number of times 3459342 can be divided by 831.

On to step 1:
3 divided by 831 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 831

Going ahead to step 2:
When dividing 34 by 831, we get 0 with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 831

Let's proceed to step 3:
The number 831 fits into 345 0 times, leaving a remainder of 345.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 345, we end up with 345.
Bring next digit (9) of the dividend behind the 345 and repeat the process: 3459 / 831

Moving on to step 4:
If we divide 3459 by 831, we get 4 and a remainder of 135.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 3324 from 3459 to get 135.
Grab the next digit (3) from the dividend, add it to 135, then carry on: 1353 / 831

Moving on to step 5:
1353 divided by 831 is 1 with a remainder of 522.
Write down 1 as next digit of the result. 
Result so far: 41.0
If we take 831 away from 1353, we end up with 522.
Include the next digit (4) from the dividend after 522, then repeat: 5224 / 831

Advancing to step 6:
The number 831 fits into 5224 6 times, leaving a remainder of 238.
Record the quotient 6 as the next digit in the result. 
Result so far: 416.0
If we subtract 4986 from 5224, we get 238.
Bring next digit (2) of the dividend behind the 238 and repeat the process: 2382 / 831

Moving on to step 7:
When dividing 2382 by 831, we get 2 with a remainder of 720.
Write down 2 as next digit of the result. 
Result so far: 4162.0
If we take 1662 away from 2382, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 8:
The number 831 fits into 7200 8 times, leaving a remainder of 552.
Record the quotient 8 as the next digit in the result. 
Result so far: 4162.8
Subtract 6648 from 7200 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 9:
When dividing 5520 by 831, we get 6 with a remainder of 534.
Write down 6 as next digit of the result. 
Result so far: 4162.86
The remainder is 534 after subtracting 4986 from 5520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Let's proceed to step 10:
When dividing 5340 by 831, we get 6 with a remainder of 354.
Put 6 as the next digit of the answer. 
Result so far: 4162.866
Deduct 4986 from 5340 and we're left with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

In conclusion, the division gives 4162.866 with a balance of 0.0354.
