Let's divide 642086 by 85
We want to figure out the number of times 642086 can be divided by 85.

Advancing to step 1:
If we divide 6 by 85, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 85

Moving on to step 2:
When dividing 64 by 85, we get 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Fetch the next digit (2) from the dividend, attach it to 64 and continue: 642 / 85

On to step 3:
If we divide 642 by 85, we get 7 and a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 595 from 642 leaves us with 47.
Take the next digit (0) from the dividend and append it to 47, then repeat: 470 / 85

Let's proceed to step 4:
470 divided by 85 is 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 75.0
If we take 425 away from 470, we end up with 45.
Take the next digit (8) from the dividend and append it to 45, then repeat: 458 / 85

On to step 5:
If we divide 458 by 85, we get 5 and a remainder of 33.
Write down 5 as next digit of the result. 
Result so far: 755.0
If we take 425 away from 458, we end up with 33.
Bring next digit (6) of the dividend behind the 33 and repeat the process: 336 / 85

Going ahead to step 6:
336 divided by 85 is 3 with a remainder of 81.
Write down 3 as next digit of the result. 
Result so far: 7553.0
Subtract 255 from 336 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 7:
85 goes into 810 9 times with a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 7553.9
Subtract 765 from 810 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
If we divide 450 by 85, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 7553.95
Deduct 425 from 450 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
250 divided by 85 is 2 with a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 7553.952
If we subtract 170 from 250, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
When dividing 800 by 85, we get 9 with a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 7553.9529
Subtract 765 from 800 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 11:
If we divide 350 by 85, we get 4 and a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 7553.95294
Subtracting 340 from 350 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
The number 85 fits into 100 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 7553.952941
Deduct 85 from 100 and we're left 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.

Step 13:
If we divide 150 by 85, we get 1 and a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 7553.9529411
The remainder is 65 after subtracting 85 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 7553.9529411 with a remainder of 6.5e-07.
