We divide 266231 by 18
We want to figure out the number of times 266231 can be divided by 18.

Step 1:
18 can be fit into 2 0 times, resulting in 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.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 18

Moving on to step 2:
If we divide 26 by 18, we get 1 and a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 18 from 26 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 18

Step 3:
When dividing 86 by 18, we get 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 14 after subtracting 72 from 86.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 18

Step 4:
18 goes into 142 7 times with a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 147.0
The remainder is 16 after subtracting 126 from 142.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 18

Going ahead to step 5:
18 can be fit into 163 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 1479.0
Subtracting 162 from 163 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 18

Step 6:
When dividing 11 by 18, we get 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 14790.0
Subtracting 0 from 11 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
18 goes into 110 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 14790.6
Deduct 108 from 110 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.

On to step 8:
18 can be fit into 20 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 14790.61
Deduct 18 from 20 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.

Step 9:
18 can be fit into 20 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 14790.611
Subtract 18 from 20 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.

The final outcome is 14790.611, with a leftover of 0.0002.
