217771 divided by 66 
We want to divide 217771 by 66.

Step 1:
2 divided by 66 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 66

On to step 2:
The number 66 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 66

Advancing to step 3:
217 divided by 66 is 3 with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 198 from 217 to get 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 66

Let's proceed to step 4:
When dividing 197 by 66, we get 2 with a remainder of 65.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Deduct 132 from 197 and we're left with 65.
Include the next digit (7) from the dividend after 65, then repeat: 657 / 66

Moving on to step 5:
When dividing 657 by 66, we get 9 with a remainder of 63.
The next digit of our result is 9. 
Result so far: 329.0
Subtracting 594 from 657 leaves us with 63.
Grab the next digit (1) from the dividend, add it to 63, then carry on: 631 / 66

Going ahead to step 6:
631 divided by 66 is 9 with a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 3299.0
Subtract 594 from 631 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 7:
370 divided by 66 is 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 3299.5
The remainder is 40 after subtracting 330 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
When dividing 400 by 66, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 3299.56
Subtract 396 from 400 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
When dividing 40 by 66, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 3299.56
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
If we divide 400 by 66, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 3299.5606
If we subtract 396 from 400, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
40 divided by 66 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 3299.5606
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
66 goes into 400 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 3299.560606
If we subtract 396 from 400, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
66 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 3299.560606
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
When dividing 400 by 66, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 3299.56060606
Subtract 396 from 400 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 3299.56060606, with a leftover of 4e-09.
