We divide 479842 by 86
We want to divide 479842 by 86.

On to step 1:
If we divide 4 by 86, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 86

Going ahead to step 2:
The number 86 fits into 47 0 times, leaving a remainder of 47.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 47 and we're left with 47.
Include the next digit (9) from the dividend after 47, then repeat: 479 / 86

Let's proceed to step 3:
The number 86 fits into 479 5 times, leaving a remainder of 49.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 430 from 479, we get 49.
Grab the next digit (8) from the dividend, add it to 49, then carry on: 498 / 86

Step 4:
86 can be fit into 498 5 times, resulting in a remainder of 68.
Use 5 as the next digit of our solution. 
Result so far: 55.0
Subtract 430 from 498 to get 68.
Grab the next digit (4) from the dividend, add it to 68, then carry on: 684 / 86

Let's proceed to step 5:
When dividing 684 by 86, we get 7 with a remainder of 82.
Put 7 as the next digit of the answer. 
Result so far: 557.0
Subtract 602 from 684 to get 82.
Grab the next digit (2) from the dividend, add it to 82, then carry on: 822 / 86

Going ahead to step 6:
The number 86 fits into 822 9 times, leaving a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 5579.0
If we subtract 774 from 822, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
480 divided by 86 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 5579.5
Deduct 430 from 480 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
500 divided by 86 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 5579.55
Deduct 430 from 500 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 5579.55 with a remaining 0.07.
