857724 ÷ 90 
Our goal is to divide 857724 by 90.

Let's proceed to step 1:
90 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 90

Going ahead to step 2:
When dividing 85 by 90, we get 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Include the next digit (7) from the dividend after 85, then repeat: 857 / 90

On to step 3:
When dividing 857 by 90, we get 9 with a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 810 from 857, we get 47.
Append the next digit (7) from the dividend to 47 and continue with: 477 / 90

Step 4:
When dividing 477 by 90, we get 5 with a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 95.0
Subtracting 450 from 477 leaves us with 27.
Take the next digit (2) from the dividend and append it to 27, then repeat: 272 / 90

On to step 5:
The number 90 fits into 272 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 953.0
If we take 270 away from 272, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 90

Let's proceed to step 6:
The number 90 fits into 24 0 times, leaving a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 9530.0
Deduct 0 from 24 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
If we divide 240 by 90, we get 2 and a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 9530.2
Deduct 180 from 240 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
600 divided by 90 is 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 9530.26
If we subtract 540 from 600, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
600 divided by 90 is 6 with a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 9530.266
Deduct 540 from 600 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 9530.266, with a leftover of 0.006.
