Let's divide 721026 by 8
The aim is to understand the frequency of 8 in 721026.

Let's proceed to step 1:
The number 8 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 8

Moving on to step 2:
8 can be fit into 72 9 times, resulting in a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 72 from 72 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 8

Step 3:
8 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 90.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 8

Let's proceed to step 4:
The number 8 fits into 10 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 901.0
The remainder is 2 after subtracting 8 from 10.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 8

Let's proceed to step 5:
8 goes into 22 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 9012.0
The remainder is 6 after subtracting 16 from 22.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 8

Advancing to step 6:
8 can be fit into 66 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 90128.0
Subtracting 64 from 66 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
If we divide 20 by 8, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 90128.2
If we subtract 16 from 20, 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.

Going ahead to step 8:
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: 90128.25
Deduct 40 from 40 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.

Let's proceed to step 9:
When dividing 0 by 8, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 90128.25
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.

Let's proceed to step 10:
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: 90128.25
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.

The final outcome is 90128.25, with a leftover of 0.0.
