Let's divide 108312 by 84
Let's see how many times 84 fits into 108312.

Moving on to step 1:
If we divide 1 by 84, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 84

On to step 2:
When dividing 10 by 84, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 84

Let's proceed to step 3:
When dividing 108 by 84, we get 1 with a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 84 from 108 to get 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 84

Let's proceed to step 4:
84 goes into 243 2 times with a remainder of 75.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 75 after subtracting 168 from 243.
Bring next digit (1) of the dividend behind the 75 and repeat the process: 751 / 84

Step 5:
751 divided by 84 is 8 with a remainder of 79.
The next digit of our result is 8. 
Result so far: 128.0
If we subtract 672 from 751, we get 79.
Fetch the next digit (2) from the dividend, attach it to 79 and continue: 792 / 84

Advancing to step 6:
The number 84 fits into 792 9 times, leaving a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 1289.0
Subtracting 756 from 792 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.

Step 7:
84 can be fit into 360 4 times, resulting in a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 1289.4
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.

On to step 8:
84 goes into 240 2 times with a remainder of 72.
The next digit of our result is 2. 
Result so far: 1289.42
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.

On to step 9:
The number 84 fits into 720 8 times, leaving a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 1289.428
Deduct 672 from 720 and we're left 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 10:
480 divided by 84 is 5 with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 1289.4285
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.

Going ahead to step 11:
600 divided by 84 is 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 1289.42857
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.

Going ahead to step 12:
The number 84 fits into 120 1 times, leaving a remainder of 36.
The next digit of our result is 1. 
Result so far: 1289.428571
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:
If we divide 360 by 84, we get 4 and a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 1289.4285714
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.

Step 14:
240 divided by 84 is 2 with a remainder of 72.
The next digit of our result is 2. 
Result so far: 1289.42857142
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.

After the division, we end up with 1289.42857142 and a remainder of 7.2e-08.
