We're dividing 483399 by 4 
We want to divide 483399 by 4.

On to step 1:
If we divide 4 by 4, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 4 from 4 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 4

On to step 2:
If we divide 8 by 4, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 8 from 8 and we're left with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 4

Advancing to step 3:
If we divide 3 by 4, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 120.0
If we subtract 0 from 3, we get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 4

Let's proceed to step 4:
The number 4 fits into 33 8 times, leaving a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 1208.0
The remainder is 1 after subtracting 32 from 33.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 4

Going ahead to step 5:
The number 4 fits into 19 4 times, leaving a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 12084.0
Subtracting 16 from 19 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 4

Going ahead to step 6:
The number 4 fits into 39 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 120849.0
If we take 36 away from 39, 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.

Moving on to step 7:
4 can be fit into 30 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 120849.7
Subtracting 28 from 30 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
When dividing 20 by 4, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 120849.75
If we take 20 away from 20, 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.

Step 9:
0 divided by 4 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 120849.75
Subtract 0 from 0 to 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.

Let's proceed to step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 120849.75
Subtract 0 from 0 to 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.

The final outcome is 120849.75, with a leftover of 0.0.
