851233 ÷ 4 
We want to divide 851233 by 4.

Let's proceed to step 1:
The number 4 fits into 8 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 8 from 8 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 4

On to step 2:
The number 4 fits into 5 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Deduct 4 from 5 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 4

Let's proceed to step 3:
4 can be fit into 11 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 212.0
If we subtract 8 from 11, we get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 4

On to step 4:
32 divided by 4 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 2128.0
The remainder is 0 after subtracting 32 from 32.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 4

Going ahead to step 5:
The number 4 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 21280.0
If we take 0 away from 3, we end up with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 4

Moving on to step 6:
If we divide 33 by 4, we get 8 and a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 212808.0
If we subtract 32 from 33, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
4 can be fit into 10 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 212808.2
Subtract 8 from 10 to 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.

Step 8:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 212808.25
If we subtract 20 from 20, 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.

Going ahead to step 9:
0 divided by 4 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 212808.25
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.

Going ahead to step 10:
0 divided by 4 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 212808.25
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 212808.25 with a remainder of 0.0.
