We're dividing 15086968 by 855 
We want to figure out the number of times 15086968 can be divided by 855.

Moving on to step 1:
1 divided by 855 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 855

Moving on to step 2:
If we divide 15 by 855, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 855

Advancing to step 3:
150 divided by 855 is 0 with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 150, we end up with 150.
Take the next digit (8) from the dividend and append it to 150, then repeat: 1508 / 855

Let's proceed to step 4:
855 goes into 1508 1 times with a remainder of 653.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 855 away from 1508, we end up with 653.
Include the next digit (6) from the dividend after 653, then repeat: 6536 / 855

Moving on to step 5:
855 can be fit into 6536 7 times, resulting in a remainder of 551.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Deduct 5985 from 6536 and we're left with 551.
Fetch the next digit (9) from the dividend, attach it to 551 and continue: 5519 / 855

Step 6:
If we divide 5519 by 855, we get 6 and a remainder of 389.
Record the quotient 6 as the next digit in the result. 
Result so far: 176.0
The remainder is 389 after subtracting 5130 from 5519.
Fetch the next digit (6) from the dividend, attach it to 389 and continue: 3896 / 855

Going ahead to step 7:
855 can be fit into 3896 4 times, resulting in a remainder of 476.
Use 4 as the next digit of our solution. 
Result so far: 1764.0
If we subtract 3420 from 3896, we get 476.
Fetch the next digit (8) from the dividend, attach it to 476 and continue: 4768 / 855

Let's proceed to step 8:
4768 divided by 855 is 5 with a remainder of 493.
The next digit of our result is 5. 
Result so far: 17645.0
Subtract 4275 from 4768 to get 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Going ahead to step 9:
The number 855 fits into 4930 5 times, leaving a remainder of 655.
Use 5 as the next digit of our solution. 
Result so far: 17645.5
Deduct 4275 from 4930 and we're left with 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Let's proceed to step 10:
6550 divided by 855 is 7 with a remainder of 565.
The number 7 becomes the next digit in our result. 
Result so far: 17645.57
The remainder is 565 after subtracting 5985 from 6550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Step 11:
855 can be fit into 5650 6 times, resulting in a remainder of 520.
The next digit of our result is 6. 
Result so far: 17645.576
If we subtract 5130 from 5650, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 12:
If we divide 5200 by 855, we get 6 and a remainder of 70.
Record the quotient 6 as the next digit in the result. 
Result so far: 17645.5766
The remainder is 70 after subtracting 5130 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 17645.5766 with a remaining 0.0007.
