We divide 266391 by 30
We want to figure out the number of times 266391 can be divided by 30.

Let's proceed to step 1:
The number 30 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 30

Advancing to step 2:
If we divide 26 by 30, we get 0 and a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 26, we end up with 26.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 30

Step 3:
The number 30 fits into 266 8 times, leaving a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 26 after subtracting 240 from 266.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 30

On to step 4:
The number 30 fits into 263 8 times, leaving a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Subtracting 240 from 263 leaves us with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 30

Advancing to step 5:
239 divided by 30 is 7 with a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 887.0
The remainder is 29 after subtracting 210 from 239.
Take the next digit (1) from the dividend and append it to 29, then repeat: 291 / 30

Let's proceed to step 6:
If we divide 291 by 30, we get 9 and a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 8879.0
Subtracting 270 from 291 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
When dividing 210 by 30, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 8879.7
If we take 210 away from 210, 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.

Moving on to step 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8879.7
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.

Going ahead to step 9:
The number 30 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 8879.7
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.

Our division results in 8879.7 with a remaining 0.0.
