321203 divided by 4 
We're looking to find how many times 4 goes into 321203.

Moving on to step 1:
The number 4 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 4

Moving on to step 2:
If we divide 32 by 4, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 0 after subtracting 32 from 32.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 4

Let's proceed to step 3:
4 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 80.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 4

Advancing to step 4:
12 divided by 4 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 803.0
If we subtract 12 from 12, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 4

Moving on to step 5:
If we divide 0 by 4, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8030.0
The remainder is 0 after subtracting 0 from 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 4

Advancing to step 6:
If we divide 3 by 4, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 80300.0
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.

Let's proceed to step 7:
When dividing 30 by 4, we get 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 80300.7
If we take 28 away from 30, we end up 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:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 80300.75
Subtracting 20 from 20 leaves us 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:
If we divide 0 by 4, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 80300.75
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.

Moving on to step 10:
0 divided by 4 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 80300.75
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 80300.75, with a leftover of 0.0.
