We look at the division of 170861 by 66 
Let's see how many times 66 fits into 170861.

Going ahead to step 1:
66 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 66

On to step 2:
66 goes into 17 0 times with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 66

Let's proceed to step 3:
66 can be fit into 170 2 times, resulting in a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 132 away from 170, we end up with 38.
Include the next digit (8) from the dividend after 38, then repeat: 388 / 66

Step 4:
66 goes into 388 5 times with a remainder of 58.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we subtract 330 from 388, we get 58.
Grab the next digit (6) from the dividend, add it to 58, then carry on: 586 / 66

Advancing to step 5:
586 divided by 66 is 8 with a remainder of 58.
The next digit of our result is 8. 
Result so far: 258.0
Subtract 528 from 586 to get 58.
Append the next digit (1) from the dividend to 58 and continue with: 581 / 66

Let's proceed to step 6:
When dividing 581 by 66, we get 8 with a remainder of 53.
Record the quotient 8 as the next digit in the result. 
Result so far: 2588.0
Subtracting 528 from 581 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 7:
When dividing 530 by 66, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 2588.8
Deduct 528 from 530 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
66 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 2588.8
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
66 goes into 200 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 2588.803
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
When dividing 20 by 66, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 2588.803
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
200 divided by 66 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 2588.80303
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
20 divided by 66 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 2588.80303
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
If we divide 200 by 66, we get 3 and a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 2588.8030303
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
66 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2588.8030303
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 2588.8030303 and a remainder of 2e-08.
