Let's divide 430249 by 90
We're looking to find how many times 90 goes into 430249.

Let's proceed to step 1:
If we divide 4 by 90, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 90

Step 2:
When dividing 43 by 90, we get 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Grab the next digit (0) from the dividend, add it to 43, then carry on: 430 / 90

Let's proceed to step 3:
The number 90 fits into 430 4 times, leaving a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 360 from 430 leaves us with 70.
Fetch the next digit (2) from the dividend, attach it to 70 and continue: 702 / 90

Let's proceed to step 4:
If we divide 702 by 90, we get 7 and a remainder of 72.
Put 7 as the next digit of the answer. 
Result so far: 47.0
If we take 630 away from 702, we end up with 72.
Append the next digit (4) from the dividend to 72 and continue with: 724 / 90

Step 5:
724 divided by 90 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 478.0
If we subtract 720 from 724, we get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 90

Going ahead to step 6:
The number 90 fits into 49 0 times, leaving a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 4780.0
The remainder is 49 after subtracting 0 from 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
The number 90 fits into 490 5 times, leaving a remainder of 40.
The next digit of our result is 5. 
Result so far: 4780.5
Deduct 450 from 490 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
When dividing 400 by 90, we get 4 with a remainder of 40.
The next digit of our result is 4. 
Result so far: 4780.54
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
If we divide 400 by 90, we get 4 and a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 4780.544
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 4780.544 with a remaining 0.004.
