578975 divided by 22 
The aim is to understand the frequency of 22 in 578975.

On to step 1:
5 divided by 22 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 22

Advancing to step 2:
When dividing 57 by 22, we get 2 with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 44 from 57 to get 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 22

On to step 3:
22 goes into 138 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 26.0
Deduct 132 from 138 and we're left with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 22

Advancing to step 4:
The number 22 fits into 69 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 263.0
Subtract 66 from 69 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 22

Advancing to step 5:
22 goes into 37 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 2631.0
Subtracting 22 from 37 leaves us with 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 22

Moving on to step 6:
The number 22 fits into 155 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 26317.0
If we take 154 away from 155, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
The number 22 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 26317.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 22, we get 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 26317.04
The remainder is 12 after subtracting 88 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
The number 22 fits into 120 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 26317.045
If we take 110 away from 120, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
22 goes into 100 4 times with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 26317.0454
Deduct 88 from 100 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
When dividing 120 by 22, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 26317.04545
Deduct 110 from 120 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
When dividing 100 by 22, we get 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 26317.045454
Deduct 88 from 100 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
22 can be fit into 120 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 26317.0454545
If we subtract 110 from 120, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
22 goes into 100 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 26317.04545454
If we subtract 88 from 100, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.
