We look at the division of 286340 by 84 
Let's see how many times 84 fits into 286340.

Moving on to step 1:
If we divide 2 by 84, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 84

Going ahead to step 2:
84 can be fit into 28 0 times, resulting in a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Append the next digit (6) from the dividend to 28 and continue with: 286 / 84

Going ahead to step 3:
84 goes into 286 3 times with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 252 from 286 leaves us with 34.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 84

Advancing to step 4:
When dividing 343 by 84, we get 4 with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtract 336 from 343 to get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 84

Going ahead to step 5:
84 goes into 74 0 times with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 340.0
The remainder is 74 after subtracting 0 from 74.
Bring next digit (0) of the dividend behind the 74 and repeat the process: 740 / 84

Step 6:
The number 84 fits into 740 8 times, leaving a remainder of 68.
The next digit of our result is 8. 
Result so far: 3408.0
The remainder is 68 after subtracting 672 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 7:
When dividing 680 by 84, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 3408.8
Subtract 672 from 680 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
The number 84 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 3408.8
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 9:
If we divide 800 by 84, we get 9 and a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 3408.809
The remainder is 44 after subtracting 756 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 10:
440 divided by 84 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 3408.8095
Subtract 420 from 440 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
If we divide 200 by 84, we get 2 and a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 3408.80952
If we take 168 away from 200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
When dividing 320 by 84, we get 3 with a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 3408.809523
If we take 252 away from 320, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 13:
84 can be fit into 680 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 3408.8095238
If we subtract 672 from 680, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
84 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 3408.8095238
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 3408.8095238 with a remainder of 8e-08.
