252236 ÷ 8 
The aim is to understand the frequency of 8 in 252236.

Let's proceed to step 1:
If we divide 2 by 8, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 8

Going ahead to step 2:
The number 8 fits into 25 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 1 after subtracting 24 from 25.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 8

Moving on to step 3:
12 divided by 8 is 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 31.0
The remainder is 4 after subtracting 8 from 12.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 8

Advancing to step 4:
8 goes into 42 5 times with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 315.0
Subtracting 40 from 42 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 8

Advancing to step 5:
When dividing 23 by 8, we get 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 3152.0
Subtracting 16 from 23 leaves us with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 8

Moving on to step 6:
The number 8 fits into 76 9 times, leaving a remainder of 4.
The next digit of our result is 9. 
Result so far: 31529.0
Deduct 72 from 76 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 7:
The number 8 fits into 40 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 31529.5
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 8:
If we divide 0 by 8, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 31529.5
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.

Advancing to step 9:
8 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 31529.5
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.

After the division, we end up with 31529.5 and a remainder of 0.0.
