We divide 849978 by 15
Let's see how many times 15 fits into 849978.

Advancing to step 1:
If we divide 8 by 15, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 15

Step 2:
15 goes into 84 5 times with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 9 after subtracting 75 from 84.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 15

Let's proceed to step 3:
If we divide 99 by 15, we get 6 and a remainder of 9.
The next digit of our result is 6. 
Result so far: 56.0
If we take 90 away from 99, we end up with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 15

Advancing to step 4:
15 goes into 99 6 times with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 566.0
Subtract 90 from 99 to get 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 15

Going ahead to step 5:
97 divided by 15 is 6 with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 5666.0
If we take 90 away from 97, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 15

On to step 6:
15 goes into 78 5 times with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 56665.0
Deduct 75 from 78 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
15 can be fit into 30 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 56665.2
Deduct 30 from 30 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 15 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 56665.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 56665.2
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 56665.2, with a leftover of 0.0.
