537771 ÷ 66 
We want to figure out the number of times 537771 can be divided by 66.

Going ahead to step 1:
If we divide 5 by 66, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 66

On to step 2:
66 can be fit into 53 0 times, resulting in a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Grab the next digit (7) from the dividend, add it to 53, then carry on: 537 / 66

Moving on to step 3:
66 can be fit into 537 8 times, resulting in a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 528 away from 537, we end up with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 66

Moving on to step 4:
When dividing 97 by 66, we get 1 with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 81.0
The remainder is 31 after subtracting 66 from 97.
Append the next digit (7) from the dividend to 31 and continue with: 317 / 66

On to step 5:
66 goes into 317 4 times with a remainder of 53.
The next digit of our result is 4. 
Result so far: 814.0
If we take 264 away from 317, we end up with 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 66

Step 6:
531 divided by 66 is 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 8148.0
If we subtract 528 from 531, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
If we divide 30 by 66, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 8148.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
If we divide 300 by 66, we get 4 and a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 8148.04
If we take 264 away from 300, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
360 divided by 66 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 8148.045
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
When dividing 300 by 66, we get 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 8148.0454
If we subtract 264 from 300, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
When dividing 360 by 66, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 8148.04545
If we take 330 away from 360, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
The number 66 fits into 300 4 times, leaving a remainder of 36.
The next digit of our result is 4. 
Result so far: 8148.045454
If we take 264 away from 300, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
360 divided by 66 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 8148.0454545
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
66 can be fit into 300 4 times, resulting in a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 8148.04545454
If we take 264 away from 300, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 8148.04545454 and a remainder of 3.6e-08.
