We divide 462490 by 90
Let's see how many times 90 fits into 462490.

Step 1:
When dividing 4 by 90, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 90

Advancing to step 2:
If we divide 46 by 90, we get 0 and a remainder of 46.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 46 leaves us with 46.
Bring next digit (2) of the dividend behind the 46 and repeat the process: 462 / 90

On to step 3:
If we divide 462 by 90, we get 5 and a remainder of 12.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 450 from 462, we get 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 90

Step 4:
When dividing 124 by 90, we get 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 51.0
If we subtract 90 from 124, we get 34.
Fetch the next digit (9) from the dividend, attach it to 34 and continue: 349 / 90

Step 5:
90 goes into 349 3 times with a remainder of 79.
The next digit of our result is 3. 
Result so far: 513.0
The remainder is 79 after subtracting 270 from 349.
Take the next digit (0) from the dividend and append it to 79, then repeat: 790 / 90

Moving on to step 6:
790 divided by 90 is 8 with a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 5138.0
The remainder is 70 after subtracting 720 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 7:
700 divided by 90 is 7 with a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 5138.7
Subtract 630 from 700 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
If we divide 700 by 90, we get 7 and a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 5138.77
Subtract 630 from 700 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 5138.77 with a remaining 0.07.
