561243 divided by 85 
We want to divide 561243 by 85.

Advancing to step 1:
When dividing 5 by 85, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 85

Step 2:
The number 85 fits into 56 0 times, leaving a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 56 to get 56.
Append the next digit (1) from the dividend to 56 and continue with: 561 / 85

Step 3:
85 goes into 561 6 times with a remainder of 51.
The next digit of our result is 6. 
Result so far: 6.0
If we take 510 away from 561, we end up with 51.
Bring next digit (2) of the dividend behind the 51 and repeat the process: 512 / 85

Let's proceed to step 4:
If we divide 512 by 85, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Deduct 510 from 512 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 85

On to step 5:
85 goes into 24 0 times with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 660.0
Subtract 0 from 24 to get 24.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 85

On to step 6:
85 can be fit into 243 2 times, resulting in a remainder of 73.
The next digit of our result is 2. 
Result so far: 6602.0
If we subtract 170 from 243, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 7:
730 divided by 85 is 8 with a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 6602.8
The remainder is 50 after subtracting 680 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
500 divided by 85 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 6602.85
Deduct 425 from 500 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 9:
If we divide 750 by 85, we get 8 and a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 6602.858
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.

Step 10:
85 goes into 700 8 times with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 6602.8588
Deduct 680 from 700 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 6602.8588, and the remainder is 0.0002.
