We divide 87638 by 8
The aim is to understand the frequency of 8 in 87638.

Step 1:
8 goes into 8 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 8 from 8 and we're left with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 8

On to step 2:
7 divided by 8 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 8

Let's proceed to step 3:
The number 8 fits into 76 9 times, leaving a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 109.0
Subtracting 72 from 76 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 8

On to step 4:
If we divide 43 by 8, we get 5 and a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 1095.0
Subtracting 40 from 43 leaves us with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 8

On to step 5:
The number 8 fits into 38 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 10954.0
If we take 32 away from 38, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 6:
8 can be fit into 60 7 times, resulting in a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 10954.7
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 10954.75
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.

Let's proceed to step 8:
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: 10954.75
If we take 0 away from 0, we end up 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.

Moving on to step 9:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10954.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 10954.75 with a remainder of 0.0.
