We're dividing 57878 by 85 
We want to figure out the number of times 57878 can be divided by 85.

Moving on to step 1:
85 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 85

Advancing to step 2:
When dividing 57 by 85, we get 0 with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Take the next digit (8) from the dividend and append it to 57, then repeat: 578 / 85

On to step 3:
The number 85 fits into 578 6 times, leaving a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 68 after subtracting 510 from 578.
Take the next digit (7) from the dividend and append it to 68, then repeat: 687 / 85

On to step 4:
85 goes into 687 8 times with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
The remainder is 7 after subtracting 680 from 687.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 85

Advancing to step 5:
85 goes into 78 0 times with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 680.0
If we subtract 0 from 78, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 6:
85 can be fit into 780 9 times, resulting in a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 680.9
If we take 765 away from 780, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
150 divided by 85 is 1 with a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 680.91
Subtracting 85 from 150 leaves us 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.

On to step 8:
If we divide 650 by 85, we get 7 and a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 680.917
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.

Moving on to step 9:
When dividing 550 by 85, we get 6 with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 680.9176
Subtract 510 from 550 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
85 can be fit into 400 4 times, resulting in a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 680.91764
Subtract 340 from 400 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
The number 85 fits into 600 7 times, leaving a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 680.917647
If we take 595 away from 600, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
If we divide 50 by 85, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 680.917647
If we take 0 away from 50, we end up 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.

Going ahead to step 13:
85 can be fit into 500 5 times, resulting in a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 680.91764705
If we subtract 425 from 500, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final outcome is 680.91764705, with a leftover of 7.5e-08.
