We're dividing 4052042 by 854 
Let's see how many times 854 fits into 4052042.

On to step 1:
854 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 854

Moving on to step 2:
If we divide 40 by 854, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 854

On to step 3:
405 divided by 854 is 0 with a remainder of 405.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 405 to get 405.
Include the next digit (2) from the dividend after 405, then repeat: 4052 / 854

Let's proceed to step 4:
4052 divided by 854 is 4 with a remainder of 636.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 3416 from 4052 and we're left with 636.
Append the next digit (0) from the dividend to 636 and continue with: 6360 / 854

On to step 5:
6360 divided by 854 is 7 with a remainder of 382.
The next digit of our result is 7. 
Result so far: 47.0
Deduct 5978 from 6360 and we're left with 382.
Fetch the next digit (4) from the dividend, attach it to 382 and continue: 3824 / 854

Going ahead to step 6:
3824 divided by 854 is 4 with a remainder of 408.
Record the quotient 4 as the next digit in the result. 
Result so far: 474.0
Subtract 3416 from 3824 to get 408.
Fetch the next digit (2) from the dividend, attach it to 408 and continue: 4082 / 854

Advancing to step 7:
The number 854 fits into 4082 4 times, leaving a remainder of 666.
The next digit of our result is 4. 
Result so far: 4744.0
The remainder is 666 after subtracting 3416 from 4082.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Going ahead to step 8:
If we divide 6660 by 854, we get 7 and a remainder of 682.
Put 7 as the next digit of the answer. 
Result so far: 4744.7
The remainder is 682 after subtracting 5978 from 6660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

On to step 9:
6820 divided by 854 is 7 with a remainder of 842.
Put 7 as the next digit of the answer. 
Result so far: 4744.77
Subtract 5978 from 6820 to get 842.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8420, and continue the process.

The final outcome is 4744.77, with a leftover of 0.842.
