We look at the division of 170509 by 84 
We want to divide 170509 by 84.

Let's proceed to step 1:
1 divided by 84 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 84

Going ahead to step 2:
84 goes into 17 0 times with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 84

Step 3:
When dividing 170 by 84, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 168 from 170, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 84

Going ahead to step 4:
84 can be fit into 25 0 times, resulting in a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 20.0
The remainder is 25 after subtracting 0 from 25.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 84

Going ahead to step 5:
84 goes into 250 2 times with a remainder of 82.
Write down 2 as next digit of the result. 
Result so far: 202.0
The remainder is 82 after subtracting 168 from 250.
Take the next digit (9) from the dividend and append it to 82, then repeat: 829 / 84

Advancing to step 6:
If we divide 829 by 84, we get 9 and a remainder of 73.
Put 9 as the next digit of the answer. 
Result so far: 2029.0
Subtract 756 from 829 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 7:
84 can be fit into 730 8 times, resulting in a remainder of 58.
The next digit of our result is 8. 
Result so far: 2029.8
Subtracting 672 from 730 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 8:
84 can be fit into 580 6 times, resulting in a remainder of 76.
Record the quotient 6 as the next digit in the result. 
Result so far: 2029.86
The remainder is 76 after subtracting 504 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 9:
The number 84 fits into 760 9 times, leaving a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 2029.869
Subtract 756 from 760 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
84 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 2029.869
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
400 divided by 84 is 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 2029.86904
Subtract 336 from 400 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
If we divide 640 by 84, we get 7 and a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 2029.869047
If we take 588 away from 640, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 13:
The number 84 fits into 520 6 times, leaving a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 2029.8690476
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
When dividing 160 by 84, we get 1 with a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 2029.86904761
Deduct 84 from 160 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

In conclusion, the division gives 2029.86904761 with a balance of 7.6e-08.
