12924151 ÷ 266 
Our goal is to divide 12924151 by 266.

Going ahead to step 1:
266 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 266

Going ahead to step 2:
When dividing 12 by 266, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 266

Advancing to step 3:
129 divided by 266 is 0 with a remainder of 129.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 129 after subtracting 0 from 129.
Fetch the next digit (2) from the dividend, attach it to 129 and continue: 1292 / 266

On to step 4:
266 goes into 1292 4 times with a remainder of 228.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 1064 from 1292 leaves us with 228.
Append the next digit (4) from the dividend to 228 and continue with: 2284 / 266

Step 5:
266 goes into 2284 8 times with a remainder of 156.
Put 8 as the next digit of the answer. 
Result so far: 48.0
The remainder is 156 after subtracting 2128 from 2284.
Fetch the next digit (1) from the dividend, attach it to 156 and continue: 1561 / 266

Advancing to step 6:
The number 266 fits into 1561 5 times, leaving a remainder of 231.
Use 5 as the next digit of our solution. 
Result so far: 485.0
If we subtract 1330 from 1561, we get 231.
Bring next digit (5) of the dividend behind the 231 and repeat the process: 2315 / 266

Let's proceed to step 7:
When dividing 2315 by 266, we get 8 with a remainder of 187.
Write down 8 as next digit of the result. 
Result so far: 4858.0
Subtract 2128 from 2315 to get 187.
Take the next digit (1) from the dividend and append it to 187, then repeat: 1871 / 266

Let's proceed to step 8:
266 can be fit into 1871 7 times, resulting in a remainder of 9.
The next digit of our result is 7. 
Result so far: 48587.0
Subtract 1862 from 1871 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
The number 266 fits into 90 0 times, leaving a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 48587.0
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 10:
900 divided by 266 is 3 with a remainder of 102.
Record the quotient 3 as the next digit in the result. 
Result so far: 48587.03
If we subtract 798 from 900, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 11:
When dividing 1020 by 266, we get 3 with a remainder of 222.
The number 3 becomes the next digit in our result. 
Result so far: 48587.033
Subtracting 798 from 1020 leaves us with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

The final outcome is 48587.033, with a leftover of 0.0222.
