109539 divided by 84 
Our goal is to divide 109539 by 84.

Step 1:
84 goes into 1 0 times 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.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 84

Step 2:
The number 84 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 84

Step 3:
84 can be fit into 109 1 times, resulting in a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 84 from 109 and we're left with 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 84

Advancing to step 4:
255 divided by 84 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 252 from 255 leaves us with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 84

Step 5:
The number 84 fits into 33 0 times, leaving a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
Deduct 0 from 33 and we're left with 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 84

Going ahead to step 6:
The number 84 fits into 339 4 times, leaving a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 1304.0
If we subtract 336 from 339, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
30 divided by 84 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 1304.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
If we divide 300 by 84, we get 3 and a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 1304.03
The remainder is 48 after subtracting 252 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
If we divide 480 by 84, we get 5 and a remainder of 60.
The next digit of our result is 5. 
Result so far: 1304.035
If we take 420 away from 480, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
600 divided by 84 is 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 1304.0357
Deduct 588 from 600 and we're left 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.

Advancing to step 11:
84 goes into 120 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 1304.03571
Deduct 84 from 120 and we're left 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.

Moving on to step 12:
When dividing 360 by 84, we get 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 1304.035714
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.

Let's proceed to step 13:
240 divided by 84 is 2 with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 1304.0357142
Subtracting 168 from 240 leaves us 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.

On to step 14:
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: 1304.03571428
Subtracting 672 from 720 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 1304.03571428, with a leftover of 4.8e-08.
