We look at the division of 434916 by 90 
Let's see how many times 90 fits into 434916.

Step 1:
4 divided by 90 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 90

Let's proceed to step 2:
The number 90 fits into 43 0 times, leaving 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.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 90

Step 3:
If we divide 434 by 90, we get 4 and a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 360 from 434 and we're left with 74.
Fetch the next digit (9) from the dividend, attach it to 74 and continue: 749 / 90

Advancing to step 4:
If we divide 749 by 90, we get 8 and a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
If we take 720 away from 749, we end up with 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 90

Advancing to step 5:
291 divided by 90 is 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 483.0
If we take 270 away from 291, we end up with 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 90

On to step 6:
If we divide 216 by 90, we get 2 and a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 4832.0
The remainder is 36 after subtracting 180 from 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
The number 90 fits into 360 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4832.4
Deduct 360 from 360 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
When dividing 0 by 90, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4832.4
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
90 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 4832.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 4832.4 with a remainder of 0.0.
