We look at the division of 5571 by 66 
We're looking to find how many times 66 goes into 5571.

Going ahead to step 1:
If we divide 5 by 66, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 66

Let's proceed to step 2:
The number 66 fits into 55 0 times, leaving a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Include the next digit (7) from the dividend after 55, then repeat: 557 / 66

On to step 3:
557 divided by 66 is 8 with a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 528 from 557 and we're left with 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 66

Moving on to step 4:
291 divided by 66 is 4 with a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Subtract 264 from 291 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 5:
If we divide 270 by 66, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 84.4
Subtracting 264 from 270 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 6:
If we divide 60 by 66, we get 0 and a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 84.4
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 7:
66 goes into 600 9 times with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 84.409
Subtract 594 from 600 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
The number 66 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 84.409
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
When dividing 600 by 66, we get 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 84.40909
Deduct 594 from 600 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
When dividing 60 by 66, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 84.40909
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
When dividing 600 by 66, we get 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 84.4090909
Subtract 594 from 600 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
60 divided by 66 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 84.4090909
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 84.4090909 with a remainder of 6e-08.
