We look at the division of 158297 by 84 
We want to figure out the number of times 158297 can be divided by 84.

Moving on to step 1:
The number 84 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 84

Moving on to step 2:
When dividing 15 by 84, we get 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 84

On to step 3:
84 goes into 158 1 times with a remainder of 74.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 84 from 158 leaves us with 74.
Bring next digit (2) of the dividend behind the 74 and repeat the process: 742 / 84

Going ahead to step 4:
If we divide 742 by 84, we get 8 and a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 70 after subtracting 672 from 742.
Include the next digit (9) from the dividend after 70, then repeat: 709 / 84

Going ahead to step 5:
709 divided by 84 is 8 with a remainder of 37.
The number 8 becomes the next digit in our result. 
Result so far: 188.0
Deduct 672 from 709 and we're left with 37.
Take the next digit (7) from the dividend and append it to 37, then repeat: 377 / 84

On to step 6:
377 divided by 84 is 4 with a remainder of 41.
Record the quotient 4 as the next digit in the result. 
Result so far: 1884.0
Deduct 336 from 377 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 7:
The number 84 fits into 410 4 times, leaving a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 1884.4
Subtracting 336 from 410 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 8:
84 can be fit into 740 8 times, resulting in a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 1884.48
If we take 672 away from 740, 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.

Going ahead to step 9:
84 can be fit into 680 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 1884.488
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.

The final result is 1884.488 with a remainder of 0.0008.
