We look at the division of 850890 by 87 
Our goal is to divide 850890 by 87.

On to step 1:
87 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 87

Step 2:
If we divide 85 by 87, we get 0 and a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Bring next digit (0) of the dividend behind the 85 and repeat the process: 850 / 87

Step 3:
850 divided by 87 is 9 with a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 783 away from 850, we end up with 67.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 87

Let's proceed to step 4:
When dividing 678 by 87, we get 7 with a remainder of 69.
Use 7 as the next digit of our solution. 
Result so far: 97.0
Subtracting 609 from 678 leaves us with 69.
Grab the next digit (9) from the dividend, add it to 69, then carry on: 699 / 87

On to step 5:
87 goes into 699 8 times with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 978.0
The remainder is 3 after subtracting 696 from 699.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 87

Step 6:
87 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 9780.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
The number 87 fits into 300 3 times, leaving a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 9780.3
The remainder is 39 after subtracting 261 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 8:
When dividing 390 by 87, we get 4 with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 9780.34
Subtract 348 from 390 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
When dividing 420 by 87, we get 4 with a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 9780.344
Subtracting 348 from 420 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 9780.344 and a remainder of 0.0072.
