We look at the division of 320394 by 84 
Let's see how many times 84 fits into 320394.

Step 1:
The number 84 fits into 3 0 times, leaving 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.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 84

Moving on to step 2:
The number 84 fits into 32 0 times, leaving a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 84

On to step 3:
The number 84 fits into 320 3 times, leaving a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 252 from 320 leaves us with 68.
Grab the next digit (3) from the dividend, add it to 68, then carry on: 683 / 84

Advancing to step 4:
If we divide 683 by 84, we get 8 and a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we subtract 672 from 683, we get 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 84

Let's proceed to step 5:
119 divided by 84 is 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 381.0
Subtract 84 from 119 to get 35.
Include the next digit (4) from the dividend after 35, then repeat: 354 / 84

Let's proceed to step 6:
The number 84 fits into 354 4 times, leaving a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 3814.0
If we subtract 336 from 354, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
180 divided by 84 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 3814.2
Subtracting 168 from 180 leaves us 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.

Step 8:
When dividing 120 by 84, we get 1 with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 3814.21
Subtract 84 from 120 to get 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 9:
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: 3814.214
If we take 336 away from 360, 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 10:
84 goes into 240 2 times with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 3814.2142
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.

Step 11:
When dividing 720 by 84, we get 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 3814.21428
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.

Advancing to step 12:
480 divided by 84 is 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 3814.214285
Subtracting 420 from 480 leaves us 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.

Let's proceed to step 13:
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: 3814.2142857
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.

Moving on to step 14:
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: 3814.21428571
Deduct 84 from 120 and we're left 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.

The final outcome is 3814.21428571, with a leftover of 3.6e-08.
