70320 ÷ 85 
Our goal is to divide 70320 by 85.

Let's proceed to step 1:
7 divided by 85 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 85

Going ahead to step 2:
If we divide 70 by 85, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Append the next digit (3) from the dividend to 70 and continue with: 703 / 85

Step 3:
When dividing 703 by 85, we get 8 with a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 680 away from 703, we end up with 23.
Grab the next digit (2) from the dividend, add it to 23, then carry on: 232 / 85

On to step 4:
If we divide 232 by 85, we get 2 and a remainder of 62.
The next digit of our result is 2. 
Result so far: 82.0
The remainder is 62 after subtracting 170 from 232.
Bring next digit (0) of the dividend behind the 62 and repeat the process: 620 / 85

On to step 5:
620 divided by 85 is 7 with a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 827.0
Subtract 595 from 620 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 6:
85 can be fit into 250 2 times, resulting in a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 827.2
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 7:
85 can be fit into 800 9 times, resulting in a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 827.29
Deduct 765 from 800 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 8:
350 divided by 85 is 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 827.294
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.

Going ahead to step 9:
85 goes into 100 1 times with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 827.2941
Subtracting 85 from 100 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.

Advancing to step 10:
The number 85 fits into 150 1 times, leaving a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 827.29411
Deduct 85 from 150 and we're left 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 outcome is 827.29411, with a leftover of 6.5e-05.
