We're dividing 129804 by 84 
We want to figure out the number of times 129804 can be divided by 84.

Going ahead to step 1:
1 divided by 84 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 84

Moving on to step 2:
When dividing 12 by 84, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 84

Going ahead to step 3:
The number 84 fits into 129 1 times, leaving a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 45 after subtracting 84 from 129.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 84

Moving on to step 4:
When dividing 458 by 84, we get 5 with a remainder of 38.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 38 after subtracting 420 from 458.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 84

Step 5:
The number 84 fits into 380 4 times, leaving a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 154.0
If we take 336 away from 380, we end up with 44.
Take the next digit (4) from the dividend and append it to 44, then repeat: 444 / 84

Advancing to step 6:
84 can be fit into 444 5 times, resulting in a remainder of 24.
The next digit of our result is 5. 
Result so far: 1545.0
Subtracting 420 from 444 leaves us with 24.
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 7:
84 goes into 240 2 times with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 1545.2
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.

Step 8:
If we divide 720 by 84, we get 8 and a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 1545.28
If we subtract 672 from 720, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
If we divide 480 by 84, we get 5 and a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 1545.285
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.

Advancing to step 10:
If we divide 600 by 84, we get 7 and a remainder of 12.
The next digit of our result is 7. 
Result so far: 1545.2857
The remainder is 12 after subtracting 588 from 600.
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 11:
The number 84 fits into 120 1 times, leaving a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1545.28571
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
84 can be fit into 360 4 times, resulting in a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 1545.285714
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
240 divided by 84 is 2 with a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 1545.2857142
The remainder is 72 after subtracting 168 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 14:
If we divide 720 by 84, we get 8 and a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 1545.28571428
If we subtract 672 from 720, we get 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 quotient of the division is 1545.28571428, and the remainder is 4.8e-08.
