We're dividing 276634 by 8 
The aim is to understand the frequency of 8 in 276634.

On to step 1:
8 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 8

Moving on to step 2:
The number 8 fits into 27 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 3 after subtracting 24 from 27.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 8

Going ahead to step 3:
8 can be fit into 36 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we take 32 away from 36, we end up with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 8

Advancing to step 4:
46 divided by 8 is 5 with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 345.0
If we take 40 away from 46, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 8

Step 5:
If we divide 63 by 8, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 3457.0
The remainder is 7 after subtracting 56 from 63.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 8

On to step 6:
If we divide 74 by 8, we get 9 and a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 34579.0
Deduct 72 from 74 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
20 divided by 8 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 34579.2
Deduct 16 from 20 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
40 divided by 8 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 34579.25
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 8 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 34579.25
The remainder is 0 after subtracting 0 from 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 10:
When dividing 0 by 8, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 34579.25
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 34579.25 and a remainder of 0.0.
