We're dividing 387666 by 85 
We want to divide 387666 by 85.

On to step 1:
85 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 85

Moving on to step 2:
The number 85 fits into 38 0 times, leaving a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Append the next digit (7) from the dividend to 38 and continue with: 387 / 85

On to step 3:
If we divide 387 by 85, we get 4 and a remainder of 47.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 340 from 387 leaves us with 47.
Grab the next digit (6) from the dividend, add it to 47, then carry on: 476 / 85

On to step 4:
85 can be fit into 476 5 times, resulting in a remainder of 51.
Use 5 as the next digit of our solution. 
Result so far: 45.0
The remainder is 51 after subtracting 425 from 476.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 85

Going ahead to step 5:
When dividing 516 by 85, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 456.0
Subtract 510 from 516 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 85

Going ahead to step 6:
66 divided by 85 is 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 4560.0
Deduct 0 from 66 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 7:
If we divide 660 by 85, we get 7 and a remainder of 65.
The number 7 becomes the next digit in our result. 
Result so far: 4560.7
Deduct 595 from 660 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 8:
650 divided by 85 is 7 with a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 4560.77
Deduct 595 from 650 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 4560.77 with a remainder of 0.055.
