Let's divide 204378 by 84
We want to figure out the number of times 204378 can be divided by 84.

Advancing to step 1:
The number 84 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 84

Let's proceed to step 2:
If we divide 20 by 84, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 84

On to step 3:
If we divide 204 by 84, we get 2 and a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 168 from 204 leaves us with 36.
Bring next digit (3) of the dividend behind the 36 and repeat the process: 363 / 84

Let's proceed to step 4:
When dividing 363 by 84, we get 4 with a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we subtract 336 from 363, we get 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 84

Moving on to step 5:
When dividing 277 by 84, we get 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 243.0
If we subtract 252 from 277, we get 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 84

Step 6:
The number 84 fits into 258 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 2433.0
Subtract 252 from 258 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
If we divide 60 by 84, we get 0 and a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 2433.0
Deduct 0 from 60 and we're left 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.

On to step 8:
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: 2433.07
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 9:
120 divided by 84 is 1 with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 2433.071
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.

On to step 10:
The number 84 fits into 360 4 times, leaving a remainder of 24.
The next digit of our result is 4. 
Result so far: 2433.0714
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.

Moving on to step 11:
84 can be fit into 240 2 times, resulting in a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 2433.07142
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.

Going ahead to step 12:
84 goes into 720 8 times with a remainder of 48.
The next digit of our result is 8. 
Result so far: 2433.071428
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.

On to step 13:
The number 84 fits into 480 5 times, leaving a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 2433.0714285
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.

Let's proceed to step 14:
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: 2433.07142857
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.

The final result is 2433.07142857 with a remainder of 1.2e-08.
