68520147 ÷ 85 
We want to figure out the number of times 68520147 can be divided by 85.

On to step 1:
6 divided by 85 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 85

Going ahead to step 2:
68 divided by 85 is 0 with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Include the next digit (5) from the dividend after 68, then repeat: 685 / 85

Let's proceed to step 3:
The number 85 fits into 685 8 times, leaving a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 680 away from 685, we end up with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 85

Moving on to step 4:
85 goes into 52 0 times with a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
If we take 0 away from 52, we end up with 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 85

Going ahead to step 5:
85 can be fit into 520 6 times, resulting in a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 806.0
The remainder is 10 after subtracting 510 from 520.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 85

Let's proceed to step 6:
The number 85 fits into 101 1 times, leaving a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 8061.0
Subtracting 85 from 101 leaves us with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 85

Let's proceed to step 7:
164 divided by 85 is 1 with a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 80611.0
The remainder is 79 after subtracting 85 from 164.
Bring next digit (7) of the dividend behind the 79 and repeat the process: 797 / 85

On to step 8:
85 goes into 797 9 times with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 806119.0
Subtracting 765 from 797 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
When dividing 320 by 85, we get 3 with a remainder of 65.
Record the quotient 3 as the next digit in the result. 
Result so far: 806119.3
If we take 255 away from 320, 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.

On to step 10:
85 can be fit into 650 7 times, resulting in a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 806119.37
Subtract 595 from 650 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 11:
85 can be fit into 550 6 times, resulting in a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 806119.376
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.

Advancing to step 12:
400 divided by 85 is 4 with a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 806119.3764
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.

Step 13:
85 goes into 600 7 times with a remainder of 5.
The next digit of our result is 7. 
Result so far: 806119.37647
The remainder is 5 after subtracting 595 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 14:
When dividing 50 by 85, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 806119.37647
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 15:
85 can be fit into 500 5 times, resulting in a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 806119.3764705
Deduct 425 from 500 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 16:
If we divide 750 by 85, we get 8 and a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 806119.37647058
If we subtract 680 from 750, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 806119.37647058 with a remaining 7e-08.
