We're dividing 12126333 by 4 
We want to divide 12126333 by 4.

Step 1:
1 divided by 4 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 4

On to step 2:
12 divided by 4 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 12 from 12 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 4

Going ahead to step 3:
1 divided by 4 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 4

Let's proceed to step 4:
12 divided by 4 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 303.0
Subtracting 12 from 12 leaves us with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 4

Going ahead to step 5:
4 goes into 6 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 3031.0
The remainder is 2 after subtracting 4 from 6.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 4

Step 6:
If we divide 23 by 4, we get 5 and a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 30315.0
The remainder is 3 after subtracting 20 from 23.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 4

On to step 7:
33 divided by 4 is 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 303158.0
Subtract 32 from 33 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 4

Advancing to step 8:
4 goes into 13 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 3031583.0
If we subtract 12 from 13, 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.

Let's proceed to step 9:
The number 4 fits into 10 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 3031583.2
Deduct 8 from 10 and we're left 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.

Moving on to step 10:
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: 3031583.25
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 11:
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: 3031583.25
Subtracting 0 from 0 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.

Moving on to step 12:
0 divided by 4 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3031583.25
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.

Our division results in 3031583.25 with a remaining 0.0.
