66449812 ÷ 555 
Let's see how many times 555 fits into 66449812.

On to step 1:
555 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 555

Advancing to step 2:
555 goes into 66 0 times with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 555

Moving on to step 3:
555 can be fit into 664 1 times, resulting in a remainder of 109.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 555 from 664 to get 109.
Grab the next digit (4) from the dividend, add it to 109, then carry on: 1094 / 555

Advancing to step 4:
1094 divided by 555 is 1 with a remainder of 539.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 539 after subtracting 555 from 1094.
Include the next digit (9) from the dividend after 539, then repeat: 5399 / 555

Let's proceed to step 5:
When dividing 5399 by 555, we get 9 with a remainder of 404.
Write down 9 as next digit of the result. 
Result so far: 119.0
Deduct 4995 from 5399 and we're left with 404.
Include the next digit (8) from the dividend after 404, then repeat: 4048 / 555

Advancing to step 6:
If we divide 4048 by 555, we get 7 and a remainder of 163.
Record the quotient 7 as the next digit in the result. 
Result so far: 1197.0
If we subtract 3885 from 4048, we get 163.
Grab the next digit (1) from the dividend, add it to 163, then carry on: 1631 / 555

Advancing to step 7:
555 goes into 1631 2 times with a remainder of 521.
The number 2 becomes the next digit in our result. 
Result so far: 11972.0
Subtract 1110 from 1631 to get 521.
Append the next digit (2) from the dividend to 521 and continue with: 5212 / 555

Step 8:
When dividing 5212 by 555, we get 9 with a remainder of 217.
The number 9 becomes the next digit in our result. 
Result so far: 119729.0
The remainder is 217 after subtracting 4995 from 5212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Going ahead to step 9:
555 goes into 2170 3 times with a remainder of 505.
Put 3 as the next digit of the answer. 
Result so far: 119729.3
If we take 1665 away from 2170, we end up with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

On to step 10:
The number 555 fits into 5050 9 times, leaving a remainder of 55.
The next digit of our result is 9. 
Result so far: 119729.39
If we subtract 4995 from 5050, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 11:
The number 555 fits into 550 0 times, leaving a remainder of 550.
The next digit of our result is 0. 
Result so far: 119729.39
If we subtract 0 from 550, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Advancing to step 12:
555 can be fit into 5500 9 times, resulting in a remainder of 505.
Write down 9 as next digit of the result. 
Result so far: 119729.3909
Deduct 4995 from 5500 and we're left with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Advancing to step 13:
If we divide 5050 by 555, we get 9 and a remainder of 55.
Write down 9 as next digit of the result. 
Result so far: 119729.39099
The remainder is 55 after subtracting 4995 from 5050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 119729.39099 and a remainder of 5.5e-05.
