15870 divided by 79 
We want to divide 15870 by 79.

Advancing to step 1:
79 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 79

Moving on to step 2:
If we divide 15 by 79, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 79

On to step 3:
158 divided by 79 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 0 after subtracting 158 from 158.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 79

Let's proceed to step 4:
79 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 79

Advancing to step 5:
79 goes into 70 0 times with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 200.0
If we take 0 away from 70, we end up 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:
79 can be fit into 700 8 times, resulting in a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 200.8
The remainder is 68 after subtracting 632 from 700.
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:
If we divide 680 by 79, we get 8 and a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 200.88
If we subtract 632 from 680, we 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.

The final result is 200.88 with a remainder of 0.048.
