We're dividing 852487 by 90 
Let's see how many times 90 fits into 852487.

Going ahead to step 1:
The number 90 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 90

Advancing to step 2:
90 can be fit into 85 0 times, resulting in a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Include the next digit (2) from the dividend after 85, then repeat: 852 / 90

Moving on to step 3:
The number 90 fits into 852 9 times, leaving a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 42 after subtracting 810 from 852.
Append the next digit (4) from the dividend to 42 and continue with: 424 / 90

Advancing to step 4:
The number 90 fits into 424 4 times, leaving a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 94.0
The remainder is 64 after subtracting 360 from 424.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 90

Let's proceed to step 5:
If we divide 648 by 90, we get 7 and a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 947.0
If we take 630 away from 648, we end up with 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 90

Let's proceed to step 6:
If we divide 187 by 90, we get 2 and a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 9472.0
Subtract 180 from 187 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
90 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 9472.0
Subtract 0 from 70 to 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.

On to step 8:
90 goes into 700 7 times with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 9472.07
Subtract 630 from 700 to 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.

On to step 9:
When dividing 700 by 90, we get 7 with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 9472.077
If we take 630 away from 700, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 9472.077, and the remainder is 0.007.
