We look at the division of 173417 by 84 
Our goal is to divide 173417 by 84.

Advancing to step 1:
1 divided by 84 is 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.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 84

Going ahead to step 2:
84 goes into 17 0 times with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 84

Advancing to step 3:
When dividing 173 by 84, we get 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 168 from 173 leaves us with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 84

On to step 4:
84 goes into 54 0 times with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 54 to get 54.
Include the next digit (1) from the dividend after 54, then repeat: 541 / 84

Advancing to step 5:
84 goes into 541 6 times with a remainder of 37.
Record the quotient 6 as the next digit in the result. 
Result so far: 206.0
Subtract 504 from 541 to get 37.
Include the next digit (7) from the dividend after 37, then repeat: 377 / 84

Going ahead to step 6:
If we divide 377 by 84, we get 4 and a remainder of 41.
Record the quotient 4 as the next digit in the result. 
Result so far: 2064.0
If we take 336 away from 377, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
410 divided by 84 is 4 with a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 2064.4
Subtracting 336 from 410 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 8:
The number 84 fits into 740 8 times, leaving a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 2064.48
The remainder is 68 after subtracting 672 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 9:
680 divided by 84 is 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 2064.488
Subtracting 672 from 680 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 2064.488, and the remainder is 0.0008.
