We're dividing 900946 by 90 
We're looking to find how many times 90 goes into 900946.

Advancing to step 1:
When dividing 9 by 90, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 90

Step 2:
90 divided by 90 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 0 after subtracting 90 from 90.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 90

Let's proceed to step 3:
The number 90 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 0 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 90

On to step 4:
9 divided by 90 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 90

Step 5:
90 goes into 94 1 times with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1001.0
Subtract 90 from 94 to get 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 90

Step 6:
When dividing 46 by 90, we get 0 with a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 10010.0
Deduct 0 from 46 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 7:
90 goes into 460 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 10010.5
Deduct 450 from 460 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 90 fits into 100 1 times, leaving a remainder of 10.
The next digit of our result is 1. 
Result so far: 10010.51
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
The number 90 fits into 100 1 times, leaving a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 10010.511
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 10010.511 with a remaining 0.001.
