48403 ÷ 4 
Our goal is to divide 48403 by 4.

Advancing to step 1:
The number 4 fits into 4 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 0 after subtracting 4 from 4.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 4

Step 2:
The number 4 fits into 8 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 8 from 8, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 4

Advancing to step 3:
The number 4 fits into 4 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
Subtract 4 from 4 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 4

Step 4:
If we divide 0 by 4, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 1210.0
The remainder is 0 after subtracting 0 from 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 4

Going ahead to step 5:
3 divided by 4 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 12100.0
If we take 0 away from 3, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 6:
4 can be fit into 30 7 times, resulting in a remainder of 2.
The next digit of our result is 7. 
Result so far: 12100.7
If we subtract 28 from 30, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 12100.75
The remainder is 0 after subtracting 20 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
4 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12100.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12100.75
Deduct 0 from 0 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.

The quotient of the division is 12100.75, and the remainder is 0.0.
