We're dividing 320349 by 84 
We want to figure out the number of times 320349 can be divided by 84.

Moving on to step 1:
84 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 84

Advancing to step 2:
If we divide 32 by 84, we get 0 and a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 32 after subtracting 0 from 32.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 84

Advancing to step 3:
When dividing 320 by 84, we get 3 with a remainder of 68.
The next digit of our result is 3. 
Result so far: 3.0
If we take 252 away from 320, we end up with 68.
Fetch the next digit (3) from the dividend, attach it to 68 and continue: 683 / 84

Step 4:
If we divide 683 by 84, we get 8 and a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Deduct 672 from 683 and we're left with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 84

Let's proceed to step 5:
The number 84 fits into 114 1 times, leaving a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 381.0
If we subtract 84 from 114, we get 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 84

On to step 6:
If we divide 309 by 84, we get 3 and a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 3813.0
Subtracting 252 from 309 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 7:
84 goes into 570 6 times with a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 3813.6
If we subtract 504 from 570, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 8:
84 can be fit into 660 7 times, resulting in a remainder of 72.
Put 7 as the next digit of the answer. 
Result so far: 3813.67
Deduct 588 from 660 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 9:
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: 3813.678
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.

On to step 10:
480 divided by 84 is 5 with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 3813.6785
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.

Advancing to step 11:
If we divide 600 by 84, we get 7 and a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 3813.67857
If we take 588 away from 600, we end up with 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 12:
When dividing 120 by 84, we get 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 3813.678571
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.

Moving on to step 13:
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: 3813.6785714
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.

Moving on to step 14:
If we divide 240 by 84, we get 2 and a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 3813.67857142
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.

After the division, we end up with 3813.67857142 and a remainder of 7.2e-08.
