We're dividing 721250 by 22 
The aim is to understand the frequency of 22 in 721250.

Let's proceed to step 1:
22 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 22

On to step 2:
The number 22 fits into 72 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 66 from 72 to get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 22

Going ahead to step 3:
61 divided by 22 is 2 with a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 32.0
The remainder is 17 after subtracting 44 from 61.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 22

Step 4:
When dividing 172 by 22, we get 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 327.0
Subtract 154 from 172 to get 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 22

Going ahead to step 5:
22 goes into 185 8 times with a remainder of 9.
The next digit of our result is 8. 
Result so far: 3278.0
The remainder is 9 after subtracting 176 from 185.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 22

Let's proceed to step 6:
22 can be fit into 90 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 32784.0
The remainder is 2 after subtracting 88 from 90.
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 7:
22 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 32784.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
The number 22 fits into 200 9 times, leaving a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 32784.09
Subtract 198 from 200 to 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.

Going ahead to step 9:
22 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 32784.09
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
200 divided by 22 is 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 32784.0909
Subtract 198 from 200 to 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.

Moving on to step 11:
20 divided by 22 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 32784.0909
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
22 goes into 200 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 32784.090909
If we take 198 away from 200, we end up 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.

Going ahead to step 13:
When dividing 20 by 22, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 32784.090909
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
The number 22 fits into 200 9 times, leaving a remainder of 2.
The next digit of our result is 9. 
Result so far: 32784.09090909
If we subtract 198 from 200, 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.

The final outcome is 32784.09090909, with a leftover of 2e-09.
