We're dividing 8268867 by 642 
We're looking to find how many times 642 goes into 8268867.

Let's proceed to step 1:
If we divide 8 by 642, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 642

Going ahead to step 2:
The number 642 fits into 82 0 times, leaving a remainder of 82.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 82, we end up with 82.
Append the next digit (6) from the dividend to 82 and continue with: 826 / 642

Moving on to step 3:
826 divided by 642 is 1 with a remainder of 184.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 642 from 826 leaves us with 184.
Bring next digit (8) of the dividend behind the 184 and repeat the process: 1848 / 642

Advancing to step 4:
1848 divided by 642 is 2 with a remainder of 564.
The next digit of our result is 2. 
Result so far: 12.0
If we take 1284 away from 1848, we end up with 564.
Append the next digit (8) from the dividend to 564 and continue with: 5648 / 642

Let's proceed to step 5:
642 goes into 5648 8 times with a remainder of 512.
The next digit of our result is 8. 
Result so far: 128.0
The remainder is 512 after subtracting 5136 from 5648.
Append the next digit (6) from the dividend to 512 and continue with: 5126 / 642

Advancing to step 6:
642 goes into 5126 7 times with a remainder of 632.
The number 7 becomes the next digit in our result. 
Result so far: 1287.0
If we subtract 4494 from 5126, we get 632.
Append the next digit (7) from the dividend to 632 and continue with: 6327 / 642

On to step 7:
If we divide 6327 by 642, we get 9 and a remainder of 549.
Use 9 as the next digit of our solution. 
Result so far: 12879.0
The remainder is 549 after subtracting 5778 from 6327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Going ahead to step 8:
If we divide 5490 by 642, we get 8 and a remainder of 354.
The number 8 becomes the next digit in our result. 
Result so far: 12879.8
Subtract 5136 from 5490 to get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Let's proceed to step 9:
3540 divided by 642 is 5 with a remainder of 330.
Put 5 as the next digit of the answer. 
Result so far: 12879.85
If we take 3210 away from 3540, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 10:
The number 642 fits into 3300 5 times, leaving a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 12879.855
Subtracting 3210 from 3300 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Our division results in 12879.855 with a remaining 0.009.
