We're dividing 165582 by 84 
We want to divide 165582 by 84.

Step 1:
84 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 84

Step 2:
The number 84 fits into 16 0 times, leaving a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 84

On to step 3:
If we divide 165 by 84, we get 1 and a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 84 from 165 and we're left with 81.
Append the next digit (5) from the dividend to 81 and continue with: 815 / 84

Advancing to step 4:
If we divide 815 by 84, we get 9 and a remainder of 59.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 756 from 815 and we're left with 59.
Append the next digit (8) from the dividend to 59 and continue with: 598 / 84

Going ahead to step 5:
598 divided by 84 is 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 197.0
The remainder is 10 after subtracting 588 from 598.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 84

Moving on to step 6:
102 divided by 84 is 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 1971.0
If we subtract 84 from 102, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
84 goes into 180 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 1971.2
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
If we divide 120 by 84, we get 1 and a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1971.21
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
360 divided by 84 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 1971.214
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
84 goes into 240 2 times with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 1971.2142
If we take 168 away from 240, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
When dividing 720 by 84, we get 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 1971.21428
The remainder is 48 after subtracting 672 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 12:
480 divided by 84 is 5 with a remainder of 60.
The next digit of our result is 5. 
Result so far: 1971.214285
If we subtract 420 from 480, we 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.

Advancing to step 13:
When dividing 600 by 84, we get 7 with a remainder of 12.
The next digit of our result is 7. 
Result so far: 1971.2142857
Subtracting 588 from 600 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
84 can be fit into 120 1 times, resulting in a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1971.21428571
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 1971.21428571 and a remainder of 3.6e-08.
