We're dividing 721973 by 85 
We want to divide 721973 by 85.

On to step 1:
If we divide 7 by 85, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 85

Going ahead to step 2:
When dividing 72 by 85, we get 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Take the next digit (1) from the dividend and append it to 72, then repeat: 721 / 85

Moving on to step 3:
721 divided by 85 is 8 with a remainder of 41.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 680 from 721 and we're left with 41.
Fetch the next digit (9) from the dividend, attach it to 41 and continue: 419 / 85

On to step 4:
If we divide 419 by 85, we get 4 and a remainder of 79.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
If we subtract 340 from 419, we get 79.
Take the next digit (7) from the dividend and append it to 79, then repeat: 797 / 85

Let's proceed to step 5:
797 divided by 85 is 9 with a remainder of 32.
The next digit of our result is 9. 
Result so far: 849.0
Deduct 765 from 797 and we're left with 32.
Bring next digit (3) of the dividend behind the 32 and repeat the process: 323 / 85

Step 6:
323 divided by 85 is 3 with a remainder of 68.
Record the quotient 3 as the next digit in the result. 
Result so far: 8493.0
Deduct 255 from 323 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 7:
680 divided by 85 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 8493.8
Subtracting 680 from 680 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 85 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8493.8
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
85 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8493.8
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 8493.8, and the remainder is 0.0.
