We look at the division of 743561 by 85 
Let's see how many times 85 fits into 743561.

Going ahead to step 1:
When dividing 7 by 85, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 85

Going ahead to step 2:
85 goes into 74 0 times with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Include the next digit (3) from the dividend after 74, then repeat: 743 / 85

Going ahead to step 3:
743 divided by 85 is 8 with a remainder of 63.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 680 from 743 and we're left with 63.
Append the next digit (5) from the dividend to 63 and continue with: 635 / 85

Advancing to step 4:
635 divided by 85 is 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 87.0
If we subtract 595 from 635, we get 40.
Take the next digit (6) from the dividend and append it to 40, then repeat: 406 / 85

Going ahead to step 5:
85 goes into 406 4 times with a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 874.0
Subtracting 340 from 406 leaves us with 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 85

Advancing to step 6:
When dividing 661 by 85, we get 7 with a remainder of 66.
Write down 7 as next digit of the result. 
Result so far: 8747.0
Subtracting 595 from 661 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 7:
The number 85 fits into 660 7 times, leaving a remainder of 65.
Write down 7 as next digit of the result. 
Result so far: 8747.7
If we subtract 595 from 660, we 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.

Going ahead to step 8:
85 can be fit into 650 7 times, resulting in a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 8747.77
If we take 595 away from 650, we end up 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.

After the division, we end up with 8747.77 and a remainder of 0.055.
