12047459 ÷ 855 
Let's see how many times 855 fits into 12047459.

Let's proceed to step 1:
When dividing 1 by 855, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 855

Going ahead to step 2:
When dividing 12 by 855, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 855

Going ahead to step 3:
120 divided by 855 is 0 with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 120 after subtracting 0 from 120.
Fetch the next digit (4) from the dividend, attach it to 120 and continue: 1204 / 855

Step 4:
The number 855 fits into 1204 1 times, leaving a remainder of 349.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 855 away from 1204, we end up with 349.
Bring next digit (7) of the dividend behind the 349 and repeat the process: 3497 / 855

Going ahead to step 5:
3497 divided by 855 is 4 with a remainder of 77.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 3420 from 3497 and we're left with 77.
Append the next digit (4) from the dividend to 77 and continue with: 774 / 855

On to step 6:
When dividing 774 by 855, we get 0 with a remainder of 774.
Write down 0 as next digit of the result. 
Result so far: 140.0
Deduct 0 from 774 and we're left with 774.
Fetch the next digit (5) from the dividend, attach it to 774 and continue: 7745 / 855

Moving on to step 7:
855 can be fit into 7745 9 times, resulting in a remainder of 50.
Put 9 as the next digit of the answer. 
Result so far: 1409.0
Subtract 7695 from 7745 to get 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 855

Going ahead to step 8:
509 divided by 855 is 0 with a remainder of 509.
Use 0 as the next digit of our solution. 
Result so far: 14090.0
The remainder is 509 after subtracting 0 from 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

On to step 9:
If we divide 5090 by 855, we get 5 and a remainder of 815.
Use 5 as the next digit of our solution. 
Result so far: 14090.5
The remainder is 815 after subtracting 4275 from 5090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8150, and continue the process.

Moving on to step 10:
855 can be fit into 8150 9 times, resulting in a remainder of 455.
Write down 9 as next digit of the result. 
Result so far: 14090.59
If we subtract 7695 from 8150, we get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Step 11:
If we divide 4550 by 855, we get 5 and a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 14090.595
Subtracting 4275 from 4550 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 12:
If we divide 2750 by 855, we get 3 and a remainder of 185.
The number 3 becomes the next digit in our result. 
Result so far: 14090.5953
Deduct 2565 from 2750 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 13:
855 goes into 1850 2 times with a remainder of 140.
Use 2 as the next digit of our solution. 
Result so far: 14090.59532
If we subtract 1710 from 1850, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 14:
The number 855 fits into 1400 1 times, leaving a remainder of 545.
The number 1 becomes the next digit in our result. 
Result so far: 14090.595321
If we take 855 away from 1400, we end up with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Going ahead to step 15:
If we divide 5450 by 855, we get 6 and a remainder of 320.
The next digit of our result is 6. 
Result so far: 14090.5953216
The remainder is 320 after subtracting 5130 from 5450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 16:
855 goes into 3200 3 times with a remainder of 635.
Record the quotient 3 as the next digit in the result. 
Result so far: 14090.59532163
The remainder is 635 after subtracting 2565 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Our division results in 14090.59532163 with a remaining 6.35e-07.
