We divide 704740 by 90
We're looking to find how many times 90 goes into 704740.

Step 1:
The number 90 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 90

On to step 2:
If we divide 70 by 90, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Take the next digit (4) from the dividend and append it to 70, then repeat: 704 / 90

Step 3:
90 goes into 704 7 times with a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 630 from 704 leaves us with 74.
Grab the next digit (7) from the dividend, add it to 74, then carry on: 747 / 90

Let's proceed to step 4:
When dividing 747 by 90, we get 8 with a remainder of 27.
The next digit of our result is 8. 
Result so far: 78.0
If we subtract 720 from 747, we get 27.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 90

Step 5:
90 goes into 274 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 783.0
If we subtract 270 from 274, we get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 90

Going ahead to step 6:
40 divided by 90 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 7830.0
If we take 0 away from 40, 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.

Step 7:
90 goes into 400 4 times with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 7830.4
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.

Let's proceed to step 8:
90 can be fit into 400 4 times, resulting in a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 7830.44
If we subtract 360 from 400, we 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.

The final outcome is 7830.44, with a leftover of 0.04.
