We look at the division of 840129 by 84 
We're looking to find how many times 84 goes into 840129.

Let's proceed to step 1:
When dividing 8 by 84, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 84

On to step 2:
If we divide 84 by 84, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we take 84 away from 84, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 84

Let's proceed to step 3:
The number 84 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 0, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 84

On to step 4:
If we divide 1 by 84, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 84

Moving on to step 5:
84 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 1000.0
If we subtract 0 from 12, we get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 84

Advancing to step 6:
The number 84 fits into 129 1 times, leaving a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 10001.0
Subtracting 84 from 129 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
84 can be fit into 450 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 10001.5
If we subtract 420 from 450, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
If we divide 300 by 84, we get 3 and a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 10001.53
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.

On to step 9:
If we divide 480 by 84, we get 5 and a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 10001.535
Subtract 420 from 480 to 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.

Moving on to step 10:
The number 84 fits into 600 7 times, leaving a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 10001.5357
Subtract 588 from 600 to get 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:
120 divided by 84 is 1 with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 10001.53571
Subtracting 84 from 120 leaves us 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.

Advancing to step 12:
The number 84 fits into 360 4 times, leaving a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 10001.535714
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.

On to step 13:
If we divide 240 by 84, we get 2 and a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 10001.5357142
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.

Let's proceed to step 14:
When dividing 720 by 84, we get 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 10001.53571428
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.

Our division results in 10001.53571428 with a remaining 4.8e-08.
