66248157 ÷ 276 
We want to figure out the number of times 66248157 can be divided by 276.

On to step 1:
The number 276 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 276

On to step 2:
The number 276 fits into 66 0 times, leaving a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Append the next digit (2) from the dividend to 66 and continue with: 662 / 276

Step 3:
276 can be fit into 662 2 times, resulting in a remainder of 110.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 552 from 662 and we're left with 110.
Include the next digit (4) from the dividend after 110, then repeat: 1104 / 276

Going ahead to step 4:
276 goes into 1104 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtracting 1104 from 1104 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 276

Let's proceed to step 5:
8 divided by 276 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 240.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 276

Step 6:
When dividing 81 by 276, we get 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 2400.0
If we subtract 0 from 81, we get 81.
Include the next digit (5) from the dividend after 81, then repeat: 815 / 276

Going ahead to step 7:
If we divide 815 by 276, we get 2 and a remainder of 263.
The number 2 becomes the next digit in our result. 
Result so far: 24002.0
Subtracting 552 from 815 leaves us with 263.
Append the next digit (7) from the dividend to 263 and continue with: 2637 / 276

Step 8:
When dividing 2637 by 276, we get 9 with a remainder of 153.
Put 9 as the next digit of the answer. 
Result so far: 240029.0
If we take 2484 away from 2637, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Let's proceed to step 9:
When dividing 1530 by 276, we get 5 with a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 240029.5
Deduct 1380 from 1530 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 10:
276 goes into 1500 5 times with a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 240029.55
If we take 1380 away from 1500, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 240029.55 and a remainder of 0.12.
