253609 divided by 8 
The aim is to understand the frequency of 8 in 253609.

Step 1:
When dividing 2 by 8, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 8

Let's proceed to step 2:
If we divide 25 by 8, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 24 from 25 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 8

Let's proceed to step 3:
If we divide 13 by 8, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 31.0
Deduct 8 from 13 and we're left with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 8

Moving on to step 4:
56 divided by 8 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 317.0
If we subtract 56 from 56, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 8

Let's proceed to step 5:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3170.0
Deduct 0 from 0 and we're left with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 8

Let's proceed to step 6:
When dividing 9 by 8, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 31701.0
The remainder is 1 after subtracting 8 from 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
8 goes into 10 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 31701.1
If we subtract 8 from 10, we 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.
Use 2 as the next digit of our solution. 
Result so far: 31701.12
The remainder is 4 after subtracting 16 from 20.
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:
The number 8 fits into 40 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 31701.125
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.

Advancing to step 10:
8 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 31701.125
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.

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: 31701.125
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.

The final outcome is 31701.125, with a leftover of 0.0.
