71558280 ÷ 66 
We're looking to find how many times 66 goes into 71558280.

Advancing to step 1:
When dividing 7 by 66, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 66

Advancing to step 2:
When dividing 71 by 66, we get 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 66 from 71, we get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 66

Advancing to step 3:
55 divided by 66 is 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 55 after subtracting 0 from 55.
Include the next digit (5) from the dividend after 55, then repeat: 555 / 66

Advancing to step 4:
66 goes into 555 8 times with a remainder of 27.
Put 8 as the next digit of the answer. 
Result so far: 108.0
The remainder is 27 after subtracting 528 from 555.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 66

Moving on to step 5:
If we divide 278 by 66, we get 4 and a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 1084.0
If we take 264 away from 278, we end up with 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 66

Step 6:
If we divide 142 by 66, we get 2 and a remainder of 10.
The next digit of our result is 2. 
Result so far: 10842.0
The remainder is 10 after subtracting 132 from 142.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 66

On to step 7:
When dividing 108 by 66, we get 1 with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 108421.0
If we take 66 away from 108, we end up with 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 66

On to step 8:
If we divide 420 by 66, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 1084216.0
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
The number 66 fits into 240 3 times, leaving a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 1084216.3
Subtract 198 from 240 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
When dividing 420 by 66, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 1084216.36
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
The number 66 fits into 240 3 times, leaving a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 1084216.363
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
When dividing 420 by 66, we get 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 1084216.3636
If we subtract 396 from 420, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
If we divide 240 by 66, we get 3 and a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 1084216.36363
If we take 198 away from 240, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 14:
If we divide 420 by 66, we get 6 and a remainder of 24.
The next digit of our result is 6. 
Result so far: 1084216.363636
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 15:
240 divided by 66 is 3 with a remainder of 42.
The next digit of our result is 3. 
Result so far: 1084216.3636363
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 16:
66 goes into 420 6 times with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 1084216.36363636
The remainder is 24 after subtracting 396 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 1084216.36363636 and a remainder of 2.4e-08.
