We divide 230644 by 90
We're looking to find how many times 90 goes into 230644.

Going ahead to step 1:
When dividing 2 by 90, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 90

Let's proceed to step 2:
23 divided by 90 is 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Append the next digit (0) from the dividend to 23 and continue with: 230 / 90

Going ahead to step 3:
When dividing 230 by 90, we get 2 with a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 50 after subtracting 180 from 230.
Grab the next digit (6) from the dividend, add it to 50, then carry on: 506 / 90

Advancing to step 4:
When dividing 506 by 90, we get 5 with a remainder of 56.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtracting 450 from 506 leaves us with 56.
Include the next digit (4) from the dividend after 56, then repeat: 564 / 90

On to step 5:
90 can be fit into 564 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 256.0
If we subtract 540 from 564, we get 24.
Grab the next digit (4) from the dividend, add it to 24, then carry on: 244 / 90

Step 6:
90 goes into 244 2 times with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 2562.0
The remainder is 64 after subtracting 180 from 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 7:
If we divide 640 by 90, we get 7 and a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 2562.7
If we take 630 away from 640, we end up 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.

Step 8:
100 divided by 90 is 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 2562.71
Deduct 90 from 100 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.

Advancing to step 9:
90 goes into 100 1 times with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 2562.711
Deduct 90 from 100 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.

After the division, we end up with 2562.711 and a remainder of 0.001.
