We divide 210988 by 8
The aim is to understand the frequency of 8 in 210988.

Moving on to step 1:
When dividing 2 by 8, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 8

On to step 2:
The number 8 fits into 21 2 times, leaving a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 16 from 21 and we're left with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 8

On to step 3:
8 can be fit into 50 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Deduct 48 from 50 and we're left with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 8

On to step 4:
When dividing 29 by 8, we get 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 263.0
Subtracting 24 from 29 leaves us with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 8

Going ahead to step 5:
8 can be fit into 58 7 times, resulting in a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 2637.0
If we take 56 away from 58, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 8

Moving on to step 6:
8 goes into 28 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 26373.0
If we subtract 24 from 28, 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.

Moving on to step 7:
40 divided by 8 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 26373.5
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
0 divided by 8 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 26373.5
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.

Step 9:
0 divided by 8 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 26373.5
Deduct 0 from 0 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.

After the division, we end up with 26373.5 and a remainder of 0.0.
