721124 divided by 85 
Let's see how many times 85 fits into 721124.

Advancing to step 1:
7 divided by 85 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 85

Advancing to step 2:
The number 85 fits into 72 0 times, leaving a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 85

On to step 3:
85 can be fit into 721 8 times, resulting in a remainder of 41.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 680 from 721 to get 41.
Grab the next digit (1) from the dividend, add it to 41, then carry on: 411 / 85

Going ahead to step 4:
85 goes into 411 4 times with a remainder of 71.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Subtract 340 from 411 to get 71.
Grab the next digit (2) from the dividend, add it to 71, then carry on: 712 / 85

Step 5:
85 can be fit into 712 8 times, resulting in a remainder of 32.
The next digit of our result is 8. 
Result so far: 848.0
Deduct 680 from 712 and we're left with 32.
Fetch the next digit (4) from the dividend, attach it to 32 and continue: 324 / 85

Advancing to step 6:
The number 85 fits into 324 3 times, leaving a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 8483.0
Subtract 255 from 324 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 7:
690 divided by 85 is 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 8483.8
The remainder is 10 after subtracting 680 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
The number 85 fits into 100 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 8483.81
If we take 85 away from 100, we end up 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 9:
The number 85 fits into 150 1 times, leaving a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 8483.811
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 quotient of the division is 8483.811, and the remainder is 0.0065.
