18687029 ÷ 266 
We want to figure out the number of times 18687029 can be divided by 266.

Moving on to step 1:
When dividing 1 by 266, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 266

Advancing to step 2:
If we divide 18 by 266, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 266

Moving on to step 3:
266 goes into 186 0 times with a remainder of 186.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 186, we end up with 186.
Take the next digit (8) from the dividend and append it to 186, then repeat: 1868 / 266

Going ahead to step 4:
266 can be fit into 1868 7 times, resulting in a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 1862 from 1868 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 266

On to step 5:
When dividing 67 by 266, we get 0 with a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
If we subtract 0 from 67, we get 67.
Append the next digit (0) from the dividend to 67 and continue with: 670 / 266

Step 6:
The number 266 fits into 670 2 times, leaving a remainder of 138.
Record the quotient 2 as the next digit in the result. 
Result so far: 702.0
If we take 532 away from 670, we end up with 138.
Fetch the next digit (2) from the dividend, attach it to 138 and continue: 1382 / 266

Going ahead to step 7:
266 goes into 1382 5 times with a remainder of 52.
The number 5 becomes the next digit in our result. 
Result so far: 7025.0
Subtracting 1330 from 1382 leaves us with 52.
Grab the next digit (9) from the dividend, add it to 52, then carry on: 529 / 266

On to step 8:
529 divided by 266 is 1 with a remainder of 263.
The number 1 becomes the next digit in our result. 
Result so far: 70251.0
If we subtract 266 from 529, we get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

On to step 9:
266 can be fit into 2630 9 times, resulting in a remainder of 236.
Put 9 as the next digit of the answer. 
Result so far: 70251.9
The remainder is 236 after subtracting 2394 from 2630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 10:
2360 divided by 266 is 8 with a remainder of 232.
Write down 8 as next digit of the result. 
Result so far: 70251.98
Subtract 2128 from 2360 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 11:
When dividing 2320 by 266, we get 8 with a remainder of 192.
Put 8 as the next digit of the answer. 
Result so far: 70251.988
Subtract 2128 from 2320 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The final outcome is 70251.988, with a leftover of 0.0192.
