We're dividing 170997 by 55 
We want to divide 170997 by 55.

Step 1:
When dividing 1 by 55, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 55

Let's proceed to step 2:
If we divide 17 by 55, we get 0 and 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 / 55

Moving on to step 3:
55 can be fit into 170 3 times, resulting in a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 165 from 170 and we're left with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 55

Let's proceed to step 4:
The number 55 fits into 59 1 times, leaving a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 31.0
The remainder is 4 after subtracting 55 from 59.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 55

Step 5:
If we divide 49 by 55, we get 0 and a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 310.0
If we subtract 0 from 49, we get 49.
Bring next digit (7) of the dividend behind the 49 and repeat the process: 497 / 55

Step 6:
55 goes into 497 9 times with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 3109.0
Subtract 495 from 497 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
20 divided by 55 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 3109.0
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 8:
The number 55 fits into 200 3 times, leaving a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 3109.03
Deduct 165 from 200 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
When dividing 350 by 55, we get 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 3109.036
If we take 330 away from 350, we end up with 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 10:
55 goes into 200 3 times with a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 3109.0363
If we take 165 away from 200, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 11:
55 can be fit into 350 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 3109.03636
If we subtract 330 from 350, 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 12:
The number 55 fits into 200 3 times, leaving a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 3109.036363
The remainder is 35 after subtracting 165 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 13:
55 goes into 350 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 3109.0363636
If we subtract 330 from 350, 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 14:
200 divided by 55 is 3 with a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 3109.03636363
Subtract 165 from 200 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 3109.03636363 with a remainder of 3.5e-08.
