We're dividing 720645 by 85 
Our goal is to divide 720645 by 85.

Advancing to step 1:
The number 85 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 85

On to step 2:
If we divide 72 by 85, we get 0 and a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Append the next digit (0) from the dividend to 72 and continue with: 720 / 85

Let's proceed to step 3:
When dividing 720 by 85, we get 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 680 from 720 and we're left with 40.
Grab the next digit (6) from the dividend, add it to 40, then carry on: 406 / 85

Let's proceed to step 4:
When dividing 406 by 85, we get 4 with a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Subtract 340 from 406 to get 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 85

Advancing to step 5:
85 goes into 664 7 times with a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 847.0
Deduct 595 from 664 and we're left with 69.
Append the next digit (5) from the dividend to 69 and continue with: 695 / 85

Step 6:
85 can be fit into 695 8 times, resulting in a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 8478.0
Subtracting 680 from 695 leaves us 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.

Going ahead to step 7:
The number 85 fits into 150 1 times, leaving a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 8478.1
Subtract 85 from 150 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 8:
When dividing 650 by 85, we get 7 with a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 8478.17
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:
85 can be fit into 550 6 times, resulting in a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 8478.176
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.

Step 10:
85 goes into 400 4 times with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 8478.1764
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.

On to step 11:
600 divided by 85 is 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 8478.17647
Subtract 595 from 600 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
The number 85 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 8478.17647
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
500 divided by 85 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 8478.1764705
The remainder is 75 after subtracting 425 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 14:
When dividing 750 by 85, we get 8 with a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 8478.17647058
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.

In conclusion, the division gives 8478.17647058 with a balance of 7e-08.
