We divide 17450639 by 8
The aim is to understand the frequency of 8 in 17450639.

Moving on to step 1:
When dividing 1 by 8, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 8

Let's proceed to step 2:
8 goes into 17 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 16 from 17 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 8

Moving on to step 3:
When dividing 14 by 8, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 8 away from 14, we end up with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 8

Advancing to step 4:
8 can be fit into 65 8 times, resulting in a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 218.0
The remainder is 1 after subtracting 64 from 65.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 8

Moving on to step 5:
If we divide 10 by 8, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 2181.0
Subtract 8 from 10 to get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 8

Moving on to step 6:
8 goes into 26 3 times with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 21813.0
Subtracting 24 from 26 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 8

Advancing to step 7:
The number 8 fits into 23 2 times, leaving a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 218132.0
The remainder is 7 after subtracting 16 from 23.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 8

Going ahead to step 8:
79 divided by 8 is 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 2181329.0
If we subtract 72 from 79, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
70 divided by 8 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 2181329.8
If we take 64 away from 70, we end up 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.

Advancing to step 10:
8 can be fit into 60 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 2181329.87
If we subtract 56 from 60, 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 11:
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: 2181329.875
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.

Moving on to step 12:
0 divided by 8 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2181329.875
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.

Advancing to step 13:
8 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2181329.875
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 final outcome is 2181329.875, with a leftover of 0.0.
