Let's divide 696129 by 8
The aim is to understand the frequency of 8 in 696129.

On to step 1:
When dividing 6 by 8, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 8

On to step 2:
If we divide 69 by 8, we get 8 and a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 64 from 69 to get 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 8

Going ahead to step 3:
The number 8 fits into 56 7 times, leaving a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
If we take 56 away from 56, we end up with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 8

Going ahead to step 4:
1 divided by 8 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 870.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 8

Going ahead to step 5:
8 can be fit into 12 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 8701.0
The remainder is 4 after subtracting 8 from 12.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 8

Going ahead to step 6:
8 goes into 49 6 times with a remainder of 1.
The next digit of our result is 6. 
Result so far: 87016.0
If we take 48 away from 49, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
8 can be fit into 10 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 87016.1
If we take 8 away from 10, 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.

Step 8:
If we divide 20 by 8, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 87016.12
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 9:
When dividing 40 by 8, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 87016.125
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.

Going ahead to step 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 87016.125
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.

Step 11:
0 divided by 8 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 87016.125
Deduct 0 from 0 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.

The final outcome is 87016.125, with a leftover of 0.0.
