We look at the division of 442813 by 86 
Our goal is to divide 442813 by 86.

Moving on to step 1:
When dividing 4 by 86, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 86

On to step 2:
The number 86 fits into 44 0 times, leaving a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 44, we get 44.
Append the next digit (2) from the dividend to 44 and continue with: 442 / 86

Step 3:
86 can be fit into 442 5 times, resulting in a remainder of 12.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 430 from 442 to get 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 86

On to step 4:
The number 86 fits into 128 1 times, leaving a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Deduct 86 from 128 and we're left with 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 86

Step 5:
421 divided by 86 is 4 with a remainder of 77.
Write down 4 as next digit of the result. 
Result so far: 514.0
Subtracting 344 from 421 leaves us with 77.
Bring next digit (3) of the dividend behind the 77 and repeat the process: 773 / 86

Step 6:
86 can be fit into 773 8 times, resulting in a remainder of 85.
The next digit of our result is 8. 
Result so far: 5148.0
Subtract 688 from 773 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 7:
86 can be fit into 850 9 times, resulting in a remainder of 76.
The number 9 becomes the next digit in our result. 
Result so far: 5148.9
Subtracting 774 from 850 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 8:
The number 86 fits into 760 8 times, leaving a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 5148.98
If we subtract 688 from 760, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
720 divided by 86 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 5148.988
The remainder is 32 after subtracting 688 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 5148.988 and a remainder of 0.0032.
