603750 ÷ 8 
The aim is to understand the frequency of 8 in 603750.

Going ahead to step 1:
The number 8 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 8

Let's proceed to step 2:
8 goes into 60 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 56 away from 60, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 8

Going ahead to step 3:
When dividing 43 by 8, we get 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Subtract 40 from 43 to get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 8

Going ahead to step 4:
If we divide 37 by 8, we get 4 and a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 754.0
Subtracting 32 from 37 leaves us with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 8

Advancing to step 5:
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: 7546.0
If we take 48 away from 55, we end up with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 8

Moving on to step 6:
The number 8 fits into 70 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 75468.0
Subtract 64 from 70 to 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.

Let's proceed to step 7:
The number 8 fits into 60 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 75468.7
Subtracting 56 from 60 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.

Advancing to step 8:
40 divided by 8 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 75468.75
Subtract 40 from 40 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.

On to step 9:
If we divide 0 by 8, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 75468.75
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.

On to step 10:
When dividing 0 by 8, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 75468.75
Subtracting 0 from 0 leaves us 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 quotient of the division is 75468.75, and the remainder is 0.0.
