We're dividing 15379844 by 859 
We want to divide 15379844 by 859.

Moving on to step 1:
1 divided by 859 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 859

Step 2:
859 goes into 15 0 times with 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.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 859

Step 3:
859 goes into 153 0 times with a remainder of 153.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 153 to get 153.
Include the next digit (7) from the dividend after 153, then repeat: 1537 / 859

Going ahead to step 4:
If we divide 1537 by 859, we get 1 and a remainder of 678.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 859 away from 1537, we end up with 678.
Include the next digit (9) from the dividend after 678, then repeat: 6789 / 859

Advancing to step 5:
6789 divided by 859 is 7 with a remainder of 776.
The next digit of our result is 7. 
Result so far: 17.0
If we take 6013 away from 6789, we end up with 776.
Take the next digit (8) from the dividend and append it to 776, then repeat: 7768 / 859

On to step 6:
859 can be fit into 7768 9 times, resulting in a remainder of 37.
The next digit of our result is 9. 
Result so far: 179.0
The remainder is 37 after subtracting 7731 from 7768.
Bring next digit (4) of the dividend behind the 37 and repeat the process: 374 / 859

Let's proceed to step 7:
859 goes into 374 0 times with a remainder of 374.
Put 0 as the next digit of the answer. 
Result so far: 1790.0
The remainder is 374 after subtracting 0 from 374.
Bring next digit (4) of the dividend behind the 374 and repeat the process: 3744 / 859

Let's proceed to step 8:
859 goes into 3744 4 times with a remainder of 308.
Use 4 as the next digit of our solution. 
Result so far: 17904.0
Subtracting 3436 from 3744 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 9:
3080 divided by 859 is 3 with a remainder of 503.
Put 3 as the next digit of the answer. 
Result so far: 17904.3
Subtracting 2577 from 3080 leaves us with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Moving on to step 10:
859 goes into 5030 5 times with a remainder of 735.
Record the quotient 5 as the next digit in the result. 
Result so far: 17904.35
If we subtract 4295 from 5030, we get 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Moving on to step 11:
The number 859 fits into 7350 8 times, leaving a remainder of 478.
The next digit of our result is 8. 
Result so far: 17904.358
If we subtract 6872 from 7350, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Step 12:
When dividing 4780 by 859, we get 5 with a remainder of 485.
Record the quotient 5 as the next digit in the result. 
Result so far: 17904.3585
Subtracting 4295 from 4780 leaves us with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

On to step 13:
If we divide 4850 by 859, we get 5 and a remainder of 555.
Write down 5 as next digit of the result. 
Result so far: 17904.35855
Subtracting 4295 from 4850 leaves us with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

The quotient of the division is 17904.35855, and the remainder is 0.000555.
