We divide 171638 by 66
Our goal is to divide 171638 by 66.

Let's proceed to step 1:
If we divide 1 by 66, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 66

Step 2:
When dividing 17 by 66, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 66

Going ahead to step 3:
When dividing 171 by 66, we get 2 with a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 132 from 171 and we're left with 39.
Append the next digit (6) from the dividend to 39 and continue with: 396 / 66

Step 4:
66 goes into 396 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
The remainder is 0 after subtracting 396 from 396.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 66

Let's proceed to step 5:
If we divide 3 by 66, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 260.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 66

Advancing to step 6:
66 can be fit into 38 0 times, resulting in a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 2600.0
Subtract 0 from 38 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.

Let's proceed to step 7:
The number 66 fits into 380 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 2600.5
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.

Advancing to step 8:
If we divide 500 by 66, we get 7 and a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 2600.57
Deduct 462 from 500 and we're left 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.

Let's proceed to step 9:
380 divided by 66 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 2600.575
Subtracting 330 from 380 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
When dividing 500 by 66, we get 7 with a remainder of 38.
The next digit of our result is 7. 
Result so far: 2600.5757
If we take 462 away from 500, we end up 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.

Let's proceed to step 11:
380 divided by 66 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 2600.57575
Subtracting 330 from 380 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
The number 66 fits into 500 7 times, leaving a remainder of 38.
The next digit of our result is 7. 
Result so far: 2600.575757
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.

Going ahead to step 13:
66 can be fit into 380 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 2600.5757575
Deduct 330 from 380 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
The number 66 fits into 500 7 times, leaving a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 2600.57575757
If we take 462 away from 500, we end up 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.

The final outcome is 2600.57575757, with a leftover of 3.8e-08.
