615451 divided by 8 
The aim is to understand the frequency of 8 in 615451.

Moving on to step 1:
6 divided by 8 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 8

Step 2:
The number 8 fits into 61 7 times, leaving a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 56 from 61 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 8

On to step 3:
8 can be fit into 55 6 times, resulting in a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
If we take 48 away from 55, we end up with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 8

Moving on to step 4:
The number 8 fits into 74 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 769.0
Subtract 72 from 74 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 8

Moving on to step 5:
If we divide 25 by 8, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 7693.0
Subtract 24 from 25 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 8

Advancing to step 6:
8 goes into 11 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 76931.0
The remainder is 3 after subtracting 8 from 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 8, we get 3 and a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 76931.3
Subtracting 24 from 30 leaves us 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.

Going ahead to step 8:
60 divided by 8 is 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 76931.37
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.

Going ahead to step 9:
40 divided by 8 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 76931.375
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.

On to step 10:
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: 76931.375
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.

Let's proceed to step 11:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 76931.375
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.

In conclusion, the division gives 76931.375 with a balance of 0.0.
