384126 ÷ 84 
We want to figure out the number of times 384126 can be divided by 84.

Step 1:
3 divided by 84 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 84

Moving on to step 2:
When dividing 38 by 84, we get 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 84

Moving on to step 3:
84 goes into 384 4 times with a remainder of 48.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 336 from 384 to get 48.
Append the next digit (1) from the dividend to 48 and continue with: 481 / 84

Moving on to step 4:
If we divide 481 by 84, we get 5 and a remainder of 61.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we take 420 away from 481, we end up with 61.
Bring next digit (2) of the dividend behind the 61 and repeat the process: 612 / 84

Step 5:
612 divided by 84 is 7 with a remainder of 24.
The next digit of our result is 7. 
Result so far: 457.0
Deduct 588 from 612 and we're left with 24.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 84

On to step 6:
84 can be fit into 246 2 times, resulting in a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 4572.0
Subtract 168 from 246 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 7:
84 can be fit into 780 9 times, resulting in a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 4572.9
If we take 756 away from 780, we end up 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 8:
240 divided by 84 is 2 with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 4572.92
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 9:
If we divide 720 by 84, we get 8 and a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 4572.928
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 10:
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: 4572.9285
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.

On to step 11:
The number 84 fits into 600 7 times, leaving a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 4572.92857
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 12:
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: 4572.928571
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 13:
When dividing 360 by 84, we get 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 4572.9285714
Deduct 336 from 360 and we're left 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.

Let's proceed to step 14:
240 divided by 84 is 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 4572.92857142
Subtract 168 from 240 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

In conclusion, the division gives 4572.92857142 with a balance of 7.2e-08.
