15862 ÷ 84 
We want to figure out the number of times 15862 can be divided by 84.

On to step 1:
84 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 84

Advancing to step 2:
When dividing 15 by 84, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 84

Moving on to step 3:
158 divided by 84 is 1 with a remainder of 74.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 84 from 158 to get 74.
Append the next digit (6) from the dividend to 74 and continue with: 746 / 84

Let's proceed to step 4:
746 divided by 84 is 8 with a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 672 from 746 and we're left with 74.
Fetch the next digit (2) from the dividend, attach it to 74 and continue: 742 / 84

Moving on to step 5:
When dividing 742 by 84, we get 8 with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 188.0
Deduct 672 from 742 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 6:
When dividing 700 by 84, we get 8 with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 188.8
The remainder is 28 after subtracting 672 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 7:
84 goes into 280 3 times with a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 188.83
Subtract 252 from 280 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
84 can be fit into 280 3 times, resulting in a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 188.833
Subtracting 252 from 280 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 188.833 with a remainder of 0.0028.
