Let's divide 54133749 by 8
The aim is to understand the frequency of 8 in 54133749.

On to step 1:
When dividing 5 by 8, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 8

On to step 2:
8 goes into 54 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 6 after subtracting 48 from 54.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 8

Going ahead to step 3:
If we divide 61 by 8, we get 7 and a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 67.0
If we subtract 56 from 61, we get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 8

Let's proceed to step 4:
8 goes into 53 6 times with a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 676.0
The remainder is 5 after subtracting 48 from 53.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 8

Moving on to step 5:
When dividing 53 by 8, we get 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 6766.0
If we subtract 48 from 53, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 8

On to step 6:
The number 8 fits into 57 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 67667.0
Subtracting 56 from 57 leaves us with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 8

On to step 7:
14 divided by 8 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 676671.0
Deduct 8 from 14 and we're left with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 8

Advancing to step 8:
If we divide 69 by 8, we get 8 and a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 6766718.0
Subtract 64 from 69 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
8 goes into 50 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 6766718.6
If we take 48 away from 50, we end up 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.

On to step 10:
20 divided by 8 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 6766718.62
Subtracting 16 from 20 leaves us 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.

Going ahead to step 11:
If we divide 40 by 8, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 6766718.625
Deduct 40 from 40 and we're left 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.

Let's proceed to step 12:
8 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 6766718.625
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.

Advancing to step 13:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6766718.625
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.

Our division results in 6766718.625 with a remaining 0.0.
