870338 ÷ 90 
We want to divide 870338 by 90.

Let's proceed to step 1:
8 divided by 90 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 90

Advancing to step 2:
When dividing 87 by 90, we get 0 with a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Bring next digit (0) of the dividend behind the 87 and repeat the process: 870 / 90

Step 3:
When dividing 870 by 90, we get 9 with a remainder of 60.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 810 from 870, we get 60.
Include the next digit (3) from the dividend after 60, then repeat: 603 / 90

Let's proceed to step 4:
90 can be fit into 603 6 times, resulting in a remainder of 63.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
Deduct 540 from 603 and we're left with 63.
Grab the next digit (3) from the dividend, add it to 63, then carry on: 633 / 90

Moving on to step 5:
If we divide 633 by 90, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 967.0
If we take 630 away from 633, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 90

Advancing to step 6:
90 goes into 38 0 times with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 9670.0
Subtract 0 from 38 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
380 divided by 90 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 9670.4
If we take 360 away from 380, we end up 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.

Advancing to step 8:
When dividing 200 by 90, we get 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 9670.42
Subtracting 180 from 200 leaves us 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.

Advancing to step 9:
When dividing 200 by 90, we get 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 9670.422
Deduct 180 from 200 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.

Our division results in 9670.422 with a remaining 0.002.
