We're dividing 320436 by 84 
Let's see how many times 84 fits into 320436.

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
If we take 0 away from 3, we end up with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 84

On to step 2:
84 goes into 32 0 times with a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 84

Step 3:
When dividing 320 by 84, we get 3 with a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 252 from 320 and we're left with 68.
Append the next digit (4) from the dividend to 68 and continue with: 684 / 84

Moving on to step 4:
When dividing 684 by 84, we get 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 38.0
If we subtract 672 from 684, we get 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 84

Moving on to step 5:
123 divided by 84 is 1 with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 381.0
The remainder is 39 after subtracting 84 from 123.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 84

Going ahead to step 6:
84 can be fit into 396 4 times, resulting in a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 3814.0
The remainder is 60 after subtracting 336 from 396.
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 goes into 600 7 times with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 3814.7
Deduct 588 from 600 and we're left 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 8:
If we divide 120 by 84, we get 1 and a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 3814.71
If we subtract 84 from 120, we 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.

Advancing to step 9:
84 can be fit into 360 4 times, resulting in a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 3814.714
Subtract 336 from 360 to 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.

Going ahead to step 10:
84 goes into 240 2 times with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 3814.7142
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.

On to step 11:
84 goes into 720 8 times with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 3814.71428
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.

Going ahead to step 12:
When dividing 480 by 84, we get 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 3814.714285
The remainder is 60 after subtracting 420 from 480.
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 13:
600 divided by 84 is 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 3814.7142857
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:
84 goes into 120 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 3814.71428571
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.

After the division, we end up with 3814.71428571 and a remainder of 3.6e-08.
