We're dividing 170957 by 83 
We're looking to find how many times 83 goes into 170957.

Going ahead to step 1:
When dividing 1 by 83, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 83

On to step 2:
If we divide 17 by 83, we get 0 and a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 83

Moving on to step 3:
When dividing 170 by 83, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 166 from 170 leaves us with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 83

On to step 4:
83 can be fit into 49 0 times, resulting in a remainder of 49.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 49, we get 49.
Bring next digit (5) of the dividend behind the 49 and repeat the process: 495 / 83

On to step 5:
The number 83 fits into 495 5 times, leaving a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 205.0
Deduct 415 from 495 and we're left with 80.
Include the next digit (7) from the dividend after 80, then repeat: 807 / 83

Advancing to step 6:
807 divided by 83 is 9 with a remainder of 60.
Write down 9 as next digit of the result. 
Result so far: 2059.0
Subtract 747 from 807 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 7:
83 can be fit into 600 7 times, resulting in a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 2059.7
Subtracting 581 from 600 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 8:
The number 83 fits into 190 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 2059.72
The remainder is 24 after subtracting 166 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
240 divided by 83 is 2 with a remainder of 74.
Put 2 as the next digit of the answer. 
Result so far: 2059.722
If we subtract 166 from 240, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final result is 2059.722 with a remainder of 0.0074.
