49959985 ÷ 66 
We want to figure out the number of times 49959985 can be divided by 66.

Let's proceed to step 1:
The number 66 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 66

Advancing to step 2:
The number 66 fits into 49 0 times, leaving a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 66

Advancing to step 3:
66 can be fit into 499 7 times, resulting in a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 462 away from 499, we end up with 37.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 66

Step 4:
66 can be fit into 375 5 times, resulting in a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
If we subtract 330 from 375, we get 45.
Append the next digit (9) from the dividend to 45 and continue with: 459 / 66

Moving on to step 5:
When dividing 459 by 66, we get 6 with a remainder of 63.
Record the quotient 6 as the next digit in the result. 
Result so far: 756.0
Subtract 396 from 459 to get 63.
Fetch the next digit (9) from the dividend, attach it to 63 and continue: 639 / 66

Advancing to step 6:
66 goes into 639 9 times with a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 7569.0
Deduct 594 from 639 and we're left with 45.
Grab the next digit (8) from the dividend, add it to 45, then carry on: 458 / 66

Going ahead to step 7:
66 goes into 458 6 times with a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 75696.0
Deduct 396 from 458 and we're left with 62.
Bring next digit (5) of the dividend behind the 62 and repeat the process: 625 / 66

Step 8:
66 can be fit into 625 9 times, resulting in a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 756969.0
Subtract 594 from 625 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
310 divided by 66 is 4 with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 756969.4
If we take 264 away from 310, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
When dividing 460 by 66, we get 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 756969.46
If we take 396 away from 460, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 11:
640 divided by 66 is 9 with a remainder of 46.
The next digit of our result is 9. 
Result so far: 756969.469
Subtracting 594 from 640 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
66 goes into 460 6 times with a remainder of 64.
The next digit of our result is 6. 
Result so far: 756969.4696
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 13:
66 can be fit into 640 9 times, resulting in a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 756969.46969
Subtracting 594 from 640 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 14:
66 can be fit into 460 6 times, resulting in a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 756969.469696
Subtracting 396 from 460 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 15:
66 can be fit into 640 9 times, resulting in a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 756969.4696969
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 16:
If we divide 460 by 66, we get 6 and a remainder of 64.
The next digit of our result is 6. 
Result so far: 756969.46969696
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 756969.46969696, and the remainder is 6.4e-08.
