We look at the division of 30146 by 84 
We want to divide 30146 by 84.

Moving on to step 1:
When dividing 3 by 84, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 84

On to step 2:
84 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 84

On to step 3:
The number 84 fits into 301 3 times, leaving a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 252 from 301, we get 49.
Bring next digit (4) of the dividend behind the 49 and repeat the process: 494 / 84

Step 4:
If we divide 494 by 84, we get 5 and a remainder of 74.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Subtracting 420 from 494 leaves us with 74.
Append the next digit (6) from the dividend to 74 and continue with: 746 / 84

On to step 5:
When dividing 746 by 84, we get 8 with a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 358.0
The remainder is 74 after subtracting 672 from 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 6:
84 can be fit into 740 8 times, resulting in a remainder of 68.
The next digit of our result is 8. 
Result so far: 358.8
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.

On to step 7:
If we divide 680 by 84, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 358.88
Subtracting 672 from 680 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 358.88 with a remaining 0.008.
