71789155 ÷ 8 
The aim is to understand the frequency of 8 in 71789155.

Step 1:
7 divided by 8 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 8

Moving on to step 2:
8 can be fit into 71 8 times, resulting in a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 64 from 71 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 8

Step 3:
8 can be fit into 77 9 times, resulting in a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
Deduct 72 from 77 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 8

Step 4:
When dividing 58 by 8, we get 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 897.0
Subtracting 56 from 58 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 8

Moving on to step 5:
The number 8 fits into 29 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 8973.0
Subtract 24 from 29 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 8

On to step 6:
The number 8 fits into 51 6 times, leaving a remainder of 3.
The next digit of our result is 6. 
Result so far: 89736.0
Subtract 48 from 51 to get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 8

Let's proceed to step 7:
When dividing 35 by 8, we get 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 897364.0
Subtracting 32 from 35 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 8

Moving on to step 8:
The number 8 fits into 35 4 times, leaving a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 8973644.0
Deduct 32 from 35 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
When dividing 30 by 8, we get 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 8973644.3
If we subtract 24 from 30, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
8 can be fit into 60 7 times, resulting in a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 8973644.37
If we subtract 56 from 60, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
The number 8 fits into 40 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 8973644.375
If we subtract 40 from 40, we 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.

Let's proceed to step 12:
When dividing 0 by 8, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8973644.375
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.

On to step 13:
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: 8973644.375
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 8973644.375 with a remainder of 0.0.
