Let's divide 309234 by 84
We're looking to find how many times 84 goes into 309234.

Going ahead to step 1:
84 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 84

Let's proceed to step 2:
When dividing 30 by 84, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 84

Going ahead to step 3:
84 can be fit into 309 3 times, resulting in a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 252 from 309 to get 57.
Bring next digit (2) of the dividend behind the 57 and repeat the process: 572 / 84

Let's proceed to step 4:
84 goes into 572 6 times with a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we take 504 away from 572, we end up with 68.
Include the next digit (3) from the dividend after 68, then repeat: 683 / 84

Moving on to step 5:
84 can be fit into 683 8 times, resulting in a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 368.0
Subtracting 672 from 683 leaves us with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 84

Step 6:
84 goes into 114 1 times with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 3681.0
If we take 84 away from 114, we end up with 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 7:
If we divide 300 by 84, we get 3 and a remainder of 48.
The next digit of our result is 3. 
Result so far: 3681.3
If we take 252 away from 300, we end up 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.

Advancing to step 8:
84 goes into 480 5 times with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 3681.35
If we subtract 420 from 480, we 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 9:
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: 3681.357
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.

Step 10:
The number 84 fits into 120 1 times, leaving a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 3681.3571
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 11:
360 divided by 84 is 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 3681.35714
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.

On to step 12:
If we divide 240 by 84, we get 2 and a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 3681.357142
Deduct 168 from 240 and we're left 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 13:
84 goes into 720 8 times with a remainder of 48.
The next digit of our result is 8. 
Result so far: 3681.3571428
Subtract 672 from 720 to 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.

Let's proceed to step 14:
480 divided by 84 is 5 with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 3681.35714285
Deduct 420 from 480 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.

After the division, we end up with 3681.35714285 and a remainder of 6e-08.
