We divide 406425 by 8
The aim is to understand the frequency of 8 in 406425.

Step 1:
If we divide 4 by 8, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 8

Going ahead to step 2:
When dividing 40 by 8, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 40 from 40 and we're left with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 8

Step 3:
8 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 50.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 8

Going ahead to step 4:
If we divide 64 by 8, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 508.0
Deduct 64 from 64 and we're left with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 8

On to step 5:
If we divide 2 by 8, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 5080.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 8

Going ahead to step 6:
When dividing 25 by 8, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 50803.0
The remainder is 1 after subtracting 24 from 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
If we divide 10 by 8, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 50803.1
Subtract 8 from 10 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
The number 8 fits into 20 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 50803.12
If we subtract 16 from 20, 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 9:
8 goes into 40 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 50803.125
If we take 40 away from 40, 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.

Moving on to step 10:
8 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 50803.125
If we subtract 0 from 0, 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.

Going ahead to step 11:
If we divide 0 by 8, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 50803.125
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 50803.125 with a balance of 0.0.
