We're dividing 4346 by 90 
Our goal is to divide 4346 by 90.

Step 1:
The number 90 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 90

Advancing to step 2:
90 can be fit into 43 0 times, resulting in a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Grab the next digit (4) from the dividend, add it to 43, then carry on: 434 / 90

Going ahead to step 3:
The number 90 fits into 434 4 times, leaving a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 360 from 434 leaves us with 74.
Fetch the next digit (6) from the dividend, attach it to 74 and continue: 746 / 90

Moving on to step 4:
746 divided by 90 is 8 with a remainder of 26.
The next digit of our result is 8. 
Result so far: 48.0
The remainder is 26 after subtracting 720 from 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 5:
90 can be fit into 260 2 times, resulting in a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 48.2
Subtract 180 from 260 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 6:
The number 90 fits into 800 8 times, leaving a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 48.28
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 7:
If we divide 800 by 90, we get 8 and a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 48.288
Subtracting 720 from 800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 48.288, and the remainder is 0.008.
