Let's divide 426730 by 90
Our goal is to divide 426730 by 90.

Let's proceed to step 1:
90 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 90

Moving on to step 2:
The number 90 fits into 42 0 times, leaving a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 90

On to step 3:
426 divided by 90 is 4 with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 360 from 426, we get 66.
Append the next digit (7) from the dividend to 66 and continue with: 667 / 90

Let's proceed to step 4:
90 goes into 667 7 times with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 47.0
The remainder is 37 after subtracting 630 from 667.
Include the next digit (3) from the dividend after 37, then repeat: 373 / 90

Step 5:
If we divide 373 by 90, we get 4 and a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 474.0
The remainder is 13 after subtracting 360 from 373.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 90

Moving on to step 6:
The number 90 fits into 130 1 times, leaving a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 4741.0
Subtract 90 from 130 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
If we divide 400 by 90, we get 4 and a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 4741.4
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
If we divide 400 by 90, we get 4 and a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 4741.44
Deduct 360 from 400 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.

In conclusion, the division gives 4741.44 with a balance of 0.04.
