We look at the division of 143243 by 22 
The aim is to understand the frequency of 22 in 143243.

Advancing to step 1:
When dividing 1 by 22, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 22

Let's proceed to step 2:
The number 22 fits into 14 0 times, leaving a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 22

Advancing to step 3:
If we divide 143 by 22, we get 6 and a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 132 from 143 to get 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 22

Moving on to step 4:
22 goes into 112 5 times with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Deduct 110 from 112 and we're left with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 22

Moving on to step 5:
When dividing 24 by 22, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 651.0
Subtract 22 from 24 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 22

Let's proceed to step 6:
23 divided by 22 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 6511.0
Subtract 22 from 23 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
22 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 6511.0
Deduct 0 from 10 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 8:
22 goes into 100 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 6511.04
Subtracting 88 from 100 leaves us 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.

Moving on to step 9:
120 divided by 22 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 6511.045
Subtract 110 from 120 to 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.

Moving on to step 10:
22 can be fit into 100 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 6511.0454
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.

Advancing to step 11:
22 can be fit into 120 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 6511.04545
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 12:
When dividing 100 by 22, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 6511.045454
Subtract 88 from 100 to 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.

Moving on to step 13:
22 can be fit into 120 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 6511.0454545
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.

Let's proceed to step 14:
The number 22 fits into 100 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 6511.04545454
If we take 88 away from 100, we end up 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.

The quotient of the division is 6511.04545454, and the remainder is 1.2e-08.
