Let's divide 812403 by 84
We're looking to find how many times 84 goes into 812403.

On to step 1:
84 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 84

Going ahead to step 2:
If we divide 81 by 84, we get 0 and a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (2) from the dividend, attach it to 81 and continue: 812 / 84

Moving on to step 3:
If we divide 812 by 84, we get 9 and a remainder of 56.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 756 from 812 to get 56.
Include the next digit (4) from the dividend after 56, then repeat: 564 / 84

On to step 4:
84 can be fit into 564 6 times, resulting in a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
If we subtract 504 from 564, we get 60.
Fetch the next digit (0) from the dividend, attach it to 60 and continue: 600 / 84

Going ahead to step 5:
If we divide 600 by 84, we get 7 and a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 967.0
Subtracting 588 from 600 leaves us with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 84

Advancing to step 6:
If we divide 123 by 84, we get 1 and a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 9671.0
The remainder is 39 after subtracting 84 from 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
390 divided by 84 is 4 with a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 9671.4
Deduct 336 from 390 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 8:
If we divide 540 by 84, we get 6 and a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 9671.46
Subtract 504 from 540 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:
If we divide 360 by 84, we get 4 and a remainder of 24.
The next digit of our result is 4. 
Result so far: 9671.464
If we subtract 336 from 360, we 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.

On to step 10:
If we divide 240 by 84, we get 2 and a remainder of 72.
The next digit of our result is 2. 
Result so far: 9671.4642
Subtract 168 from 240 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to 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: 9671.46428
If we subtract 672 from 720, we 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.

On to step 12:
84 can be fit into 480 5 times, resulting in a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 9671.464285
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.

Moving on to step 13:
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: 9671.4642857
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 14:
84 can be fit into 120 1 times, resulting in a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 9671.46428571
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.

After the division, we end up with 9671.46428571 and a remainder of 3.6e-08.
