4125319 ÷ 842 
Let's see how many times 842 fits into 4125319.

Moving on to step 1:
842 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 842

Going ahead to step 2:
If we divide 41 by 842, we get 0 and a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 41, we end up with 41.
Grab the next digit (2) from the dividend, add it to 41, then carry on: 412 / 842

Moving on to step 3:
412 divided by 842 is 0 with a remainder of 412.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 412 after subtracting 0 from 412.
Fetch the next digit (5) from the dividend, attach it to 412 and continue: 4125 / 842

Going ahead to step 4:
When dividing 4125 by 842, we get 4 with a remainder of 757.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 3368 from 4125, we get 757.
Append the next digit (3) from the dividend to 757 and continue with: 7573 / 842

Going ahead to step 5:
7573 divided by 842 is 8 with a remainder of 837.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we take 6736 away from 7573, we end up with 837.
Take the next digit (1) from the dividend and append it to 837, then repeat: 8371 / 842

Moving on to step 6:
8371 divided by 842 is 9 with a remainder of 793.
Write down 9 as next digit of the result. 
Result so far: 489.0
The remainder is 793 after subtracting 7578 from 8371.
Take the next digit (9) from the dividend and append it to 793, then repeat: 7939 / 842

Going ahead to step 7:
842 goes into 7939 9 times with a remainder of 361.
Write down 9 as next digit of the result. 
Result so far: 4899.0
If we take 7578 away from 7939, we end up with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Step 8:
3610 divided by 842 is 4 with a remainder of 242.
Record the quotient 4 as the next digit in the result. 
Result so far: 4899.4
If we take 3368 away from 3610, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 9:
When dividing 2420 by 842, we get 2 with a remainder of 736.
Use 2 as the next digit of our solution. 
Result so far: 4899.42
Subtracting 1684 from 2420 leaves us with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Going ahead to step 10:
7360 divided by 842 is 8 with a remainder of 624.
The next digit of our result is 8. 
Result so far: 4899.428
Subtract 6736 from 7360 to get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Going ahead to step 11:
The number 842 fits into 6240 7 times, leaving a remainder of 346.
The next digit of our result is 7. 
Result so far: 4899.4287
Subtracting 5894 from 6240 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

On to step 12:
842 can be fit into 3460 4 times, resulting in a remainder of 92.
Put 4 as the next digit of the answer. 
Result so far: 4899.42874
If we take 3368 away from 3460, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 13:
920 divided by 842 is 1 with a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 4899.428741
Subtracting 842 from 920 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 14:
The number 842 fits into 780 0 times, leaving a remainder of 780.
The next digit of our result is 0. 
Result so far: 4899.428741
If we take 0 away from 780, we end up with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

On to step 15:
If we divide 7800 by 842, we get 9 and a remainder of 222.
The next digit of our result is 9. 
Result so far: 4899.42874109
If we take 7578 away from 7800, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

The final outcome is 4899.42874109, with a leftover of 2.22e-07.
