Let's divide 437708 by 90
Our goal is to divide 437708 by 90.

Going ahead to step 1:
If we divide 4 by 90, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 90

On to step 2:
90 goes into 43 0 times with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Append the next digit (7) from the dividend to 43 and continue with: 437 / 90

Let's proceed to step 3:
90 goes into 437 4 times with a remainder of 77.
The next digit of our result is 4. 
Result so far: 4.0
If we take 360 away from 437, we end up with 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 90

Step 4:
If we divide 777 by 90, we get 8 and a remainder of 57.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtract 720 from 777 to get 57.
Grab the next digit (0) from the dividend, add it to 57, then carry on: 570 / 90

On to step 5:
If we divide 570 by 90, we get 6 and a remainder of 30.
The next digit of our result is 6. 
Result so far: 486.0
If we take 540 away from 570, we end up with 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 90

Advancing to step 6:
90 goes into 308 3 times with a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 4863.0
If we take 270 away from 308, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
380 divided by 90 is 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 4863.4
Subtract 360 from 380 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
If we divide 200 by 90, we get 2 and a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 4863.42
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
90 can be fit into 200 2 times, resulting in a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 4863.422
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 4863.422, with a leftover of 0.002.
