Let's divide 386124 by 84
We want to figure out the number of times 386124 can be divided by 84.

Going ahead to step 1:
3 divided by 84 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 84

Step 2:
84 goes into 38 0 times with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 84

Step 3:
When dividing 386 by 84, we get 4 with a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 50 after subtracting 336 from 386.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 84

Let's proceed to step 4:
The number 84 fits into 501 5 times, leaving a remainder of 81.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
The remainder is 81 after subtracting 420 from 501.
Bring next digit (2) of the dividend behind the 81 and repeat the process: 812 / 84

Advancing to step 5:
The number 84 fits into 812 9 times, leaving a remainder of 56.
The number 9 becomes the next digit in our result. 
Result so far: 459.0
If we subtract 756 from 812, we get 56.
Bring next digit (4) of the dividend behind the 56 and repeat the process: 564 / 84

Moving on to step 6:
84 can be fit into 564 6 times, resulting in a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 4596.0
Deduct 504 from 564 and we're left 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.

Moving on to step 7:
84 can be fit into 600 7 times, resulting in a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 4596.7
If we subtract 588 from 600, we 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.

Let's proceed to step 8:
84 goes into 120 1 times with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 4596.71
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.

Going ahead to step 9:
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: 4596.714
If we subtract 336 from 360, we get 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 10:
The number 84 fits into 240 2 times, leaving a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 4596.7142
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.

Advancing to step 11:
When dividing 720 by 84, we get 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 4596.71428
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.

Moving on to step 12:
The number 84 fits into 480 5 times, leaving a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 4596.714285
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.

Step 13:
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: 4596.7142857
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.

Moving on to step 14:
120 divided by 84 is 1 with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 4596.71428571
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.

The final outcome is 4596.71428571, with a leftover of 3.6e-08.
