726378 ÷ 22 
The aim is to understand the frequency of 22 in 726378.

Step 1:
7 divided by 22 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 22

Going ahead to step 2:
If we divide 72 by 22, we get 3 and a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 66 from 72 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 22

Moving on to step 3:
66 divided by 22 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 33.0
The remainder is 0 after subtracting 66 from 66.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 22

Moving on to step 4:
The number 22 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 330.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 22

Step 5:
22 goes into 37 1 times with a remainder of 15.
The next digit of our result is 1. 
Result so far: 3301.0
Deduct 22 from 37 and we're left with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 22

Moving on to step 6:
If we divide 158 by 22, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 33017.0
Subtract 154 from 158 to 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.

Let's proceed to step 7:
22 goes into 40 1 times with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 33017.1
The remainder is 18 after subtracting 22 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
22 goes into 180 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 33017.18
If we take 176 away from 180, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
If we divide 40 by 22, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 33017.181
If we take 22 away from 40, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
22 can be fit into 180 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 33017.1818
The remainder is 4 after subtracting 176 from 180.
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 11:
When dividing 40 by 22, we get 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 33017.18181
Deduct 22 from 40 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 12:
When dividing 180 by 22, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 33017.181818
If we take 176 away from 180, we end up with 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 13:
40 divided by 22 is 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 33017.1818181
Subtracting 22 from 40 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
22 goes into 180 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 33017.18181818
Subtract 176 from 180 to 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.

The final result is 33017.18181818 with a remainder of 4e-09.
