Let's divide 37589825 by 8
The aim is to understand the frequency of 8 in 37589825.

Step 1:
If we divide 3 by 8, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 8

On to step 2:
If we divide 37 by 8, we get 4 and a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 32 away from 37, we end up with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 8

Let's proceed to step 3:
If we divide 55 by 8, we get 6 and a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
Subtract 48 from 55 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 8

Advancing to step 4:
8 goes into 78 9 times with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 469.0
The remainder is 6 after subtracting 72 from 78.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 8

Step 5:
8 goes into 69 8 times with a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 4698.0
If we take 64 away from 69, we end up with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 8

Moving on to step 6:
If we divide 58 by 8, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 46987.0
Subtracting 56 from 58 leaves us with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 8

Step 7:
8 can be fit into 22 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 469872.0
If we take 16 away from 22, we end up with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 8

On to step 8:
If we divide 65 by 8, we get 8 and a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 4698728.0
Deduct 64 from 65 and we're left 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.

On to step 9:
If we divide 10 by 8, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 4698728.1
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.

Moving on to step 10:
The number 8 fits into 20 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 4698728.12
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.

Moving on to step 11:
8 goes into 40 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4698728.125
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.

Step 12:
8 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4698728.125
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.

Step 13:
0 divided by 8 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4698728.125
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.

The final outcome is 4698728.125, with a leftover of 0.0.
