66729854 divided by 268 
Let's see how many times 268 fits into 66729854.

Advancing to step 1:
If we divide 6 by 268, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 268

Advancing to step 2:
268 can be fit into 66 0 times, resulting in a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Fetch the next digit (7) from the dividend, attach it to 66 and continue: 667 / 268

Advancing to step 3:
The number 268 fits into 667 2 times, leaving a remainder of 131.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 536 away from 667, we end up with 131.
Fetch the next digit (2) from the dividend, attach it to 131 and continue: 1312 / 268

Let's proceed to step 4:
268 can be fit into 1312 4 times, resulting in a remainder of 240.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we subtract 1072 from 1312, we get 240.
Append the next digit (9) from the dividend to 240 and continue with: 2409 / 268

On to step 5:
If we divide 2409 by 268, we get 8 and a remainder of 265.
Use 8 as the next digit of our solution. 
Result so far: 248.0
The remainder is 265 after subtracting 2144 from 2409.
Include the next digit (8) from the dividend after 265, then repeat: 2658 / 268

Step 6:
When dividing 2658 by 268, we get 9 with a remainder of 246.
Put 9 as the next digit of the answer. 
Result so far: 2489.0
If we subtract 2412 from 2658, we get 246.
Grab the next digit (5) from the dividend, add it to 246, then carry on: 2465 / 268

Let's proceed to step 7:
2465 divided by 268 is 9 with a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 24899.0
Subtracting 2412 from 2465 leaves us with 53.
Fetch the next digit (4) from the dividend, attach it to 53 and continue: 534 / 268

Moving on to step 8:
268 can be fit into 534 1 times, resulting in a remainder of 266.
Use 1 as the next digit of our solution. 
Result so far: 248991.0
If we take 268 away from 534, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Step 9:
If we divide 2660 by 268, we get 9 and a remainder of 248.
The next digit of our result is 9. 
Result so far: 248991.9
Deduct 2412 from 2660 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 10:
268 can be fit into 2480 9 times, resulting in a remainder of 68.
The next digit of our result is 9. 
Result so far: 248991.99
Deduct 2412 from 2480 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

After the division, we end up with 248991.99 and a remainder of 0.068.
