266398 ÷ 4 
We want to divide 266398 by 4.

Advancing to step 1:
When dividing 2 by 4, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 4

Step 2:
The number 4 fits into 26 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 24 from 26 to get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 4

Going ahead to step 3:
The number 4 fits into 26 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Subtracting 24 from 26 leaves us with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 4

Going ahead to step 4:
4 goes into 23 5 times with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 665.0
The remainder is 3 after subtracting 20 from 23.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 4

Going ahead to step 5:
39 divided by 4 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 6659.0
If we subtract 36 from 39, we get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 4

Step 6:
When dividing 38 by 4, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 66599.0
The remainder is 2 after subtracting 36 from 38.
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:
When dividing 20 by 4, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 66599.5
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.

Let's proceed to step 8:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 66599.5
If we take 0 away from 0, 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:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 66599.5
If we take 0 away from 0, 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.

After the division, we end up with 66599.5 and a remainder of 0.0.
