Let's divide 423978 by 22
The aim is to understand the frequency of 22 in 423978.

Moving on to step 1:
When dividing 4 by 22, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 22

Let's proceed to step 2:
22 can be fit into 42 1 times, resulting in a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 22 from 42 to get 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 22

On to step 3:
When dividing 203 by 22, we get 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtracting 198 from 203 leaves us with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 22

Advancing to step 4:
59 divided by 22 is 2 with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 192.0
Deduct 44 from 59 and we're left with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 22

Let's proceed to step 5:
22 goes into 157 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 1927.0
If we subtract 154 from 157, we get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 22

Moving on to step 6:
If we divide 38 by 22, we get 1 and a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 19271.0
The remainder is 16 after subtracting 22 from 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
22 goes into 160 7 times with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 19271.7
Subtracting 154 from 160 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
22 goes into 60 2 times with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 19271.72
If we take 44 away from 60, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
22 can be fit into 160 7 times, resulting in a remainder of 6.
The next digit of our result is 7. 
Result so far: 19271.727
Subtract 154 from 160 to 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.

Moving on to step 10:
22 goes into 60 2 times with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 19271.7272
The remainder is 16 after subtracting 44 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
22 can be fit into 160 7 times, resulting in a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 19271.72727
The remainder is 6 after subtracting 154 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
60 divided by 22 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 19271.727272
The remainder is 16 after subtracting 44 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
If we divide 160 by 22, we get 7 and a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 19271.7272727
If we subtract 154 from 160, 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.

Let's proceed to step 14:
If we divide 60 by 22, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 19271.72727272
Subtract 44 from 60 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 19271.72727272, with a leftover of 1.6e-08.
