615311 divided by 85 
We want to figure out the number of times 615311 can be divided by 85.

Step 1:
6 divided by 85 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 85

On to step 2:
When dividing 61 by 85, we get 0 with a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Include the next digit (5) from the dividend after 61, then repeat: 615 / 85

On to step 3:
When dividing 615 by 85, we get 7 with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 595 from 615 leaves us with 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 85

Moving on to step 4:
85 goes into 203 2 times with a remainder of 33.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
Subtracting 170 from 203 leaves us with 33.
Grab the next digit (1) from the dividend, add it to 33, then carry on: 331 / 85

Step 5:
85 can be fit into 331 3 times, resulting in a remainder of 76.
The next digit of our result is 3. 
Result so far: 723.0
Deduct 255 from 331 and we're left with 76.
Take the next digit (1) from the dividend and append it to 76, then repeat: 761 / 85

On to step 6:
761 divided by 85 is 8 with a remainder of 81.
Write down 8 as next digit of the result. 
Result so far: 7238.0
Subtracting 680 from 761 leaves us with 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:
When dividing 810 by 85, we get 9 with a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 7238.9
Subtracting 765 from 810 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 8:
If we divide 450 by 85, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 7238.95
Subtracting 425 from 450 leaves us 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.

Moving on to step 9:
When dividing 250 by 85, we get 2 with a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 7238.952
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.

Let's proceed to step 10:
If we divide 800 by 85, we get 9 and a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 7238.9529
If we subtract 765 from 800, we 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:
85 can be fit into 350 4 times, resulting in a remainder of 10.
The next digit of our result is 4. 
Result so far: 7238.95294
If we take 340 away from 350, we end up 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.

Let's proceed to step 12:
85 goes into 100 1 times with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 7238.952941
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.

Let's proceed to step 13:
150 divided by 85 is 1 with a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 7238.9529411
If we take 85 away from 150, we end up 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.

The final result is 7238.9529411 with a remainder of 6.5e-07.
