We look at the division of 1721 by 66 
We want to divide 1721 by 66.

Moving on to step 1:
If we divide 1 by 66, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 66

Let's proceed to step 2:
66 goes into 17 0 times with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 66

Going ahead to step 3:
If we divide 172 by 66, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 40 after subtracting 132 from 172.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 66

On to step 4:
If we divide 401 by 66, we get 6 and a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Deduct 396 from 401 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 5:
50 divided by 66 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 26.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 6:
If we divide 500 by 66, we get 7 and a remainder of 38.
The next digit of our result is 7. 
Result so far: 26.07
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
The number 66 fits into 380 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 26.075
Subtract 330 from 380 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
66 goes into 500 7 times with a remainder of 38.
The next digit of our result is 7. 
Result so far: 26.0757
Subtract 462 from 500 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
When dividing 380 by 66, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 26.07575
The remainder is 50 after subtracting 330 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
500 divided by 66 is 7 with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 26.075757
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 11:
66 can be fit into 380 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 26.0757575
Subtract 330 from 380 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
66 goes into 500 7 times with a remainder of 38.
The next digit of our result is 7. 
Result so far: 26.07575757
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

In conclusion, the division gives 26.07575757 with a balance of 3.8e-08.
