221999 divided by 8 
The aim is to understand the frequency of 8 in 221999.

On to step 1:
2 divided by 8 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 8

Let's proceed to step 2:
8 goes into 22 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 16 from 22 and we're left with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 8

Going ahead to step 3:
8 goes into 61 7 times with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtracting 56 from 61 leaves us with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 8

Let's proceed to step 4:
8 can be fit into 59 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 277.0
Subtracting 56 from 59 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 8

Let's proceed to step 5:
The number 8 fits into 39 4 times, leaving a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 2774.0
Deduct 32 from 39 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 8

Step 6:
8 goes into 79 9 times with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 27749.0
Subtract 72 from 79 to 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.

Moving on to step 7:
The number 8 fits into 70 8 times, leaving a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 27749.8
If we subtract 64 from 70, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
If we divide 60 by 8, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 27749.87
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 9:
If we divide 40 by 8, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 27749.875
If we subtract 40 from 40, 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 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 27749.875
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.

Going ahead to step 11:
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: 27749.875
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 27749.875, with a leftover of 0.0.
