We look at the division of 20440226 by 243 
The aim is to understand the frequency of 243 in 20440226.

Going ahead to step 1:
When dividing 2 by 243, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 243

Moving on to step 2:
243 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 243

Step 3:
When dividing 204 by 243, we get 0 with a remainder of 204.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 204 to get 204.
Bring next digit (4) of the dividend behind the 204 and repeat the process: 2044 / 243

On to step 4:
2044 divided by 243 is 8 with a remainder of 100.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 1944 from 2044, we get 100.
Grab the next digit (0) from the dividend, add it to 100, then carry on: 1000 / 243

Advancing to step 5:
If we divide 1000 by 243, we get 4 and a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 84.0
Deduct 972 from 1000 and we're left with 28.
Fetch the next digit (2) from the dividend, attach it to 28 and continue: 282 / 243

Step 6:
282 divided by 243 is 1 with a remainder of 39.
The next digit of our result is 1. 
Result so far: 841.0
If we subtract 243 from 282, we get 39.
Bring next digit (2) of the dividend behind the 39 and repeat the process: 392 / 243

On to step 7:
243 can be fit into 392 1 times, resulting in a remainder of 149.
Record the quotient 1 as the next digit in the result. 
Result so far: 8411.0
If we subtract 243 from 392, we get 149.
Include the next digit (6) from the dividend after 149, then repeat: 1496 / 243

Let's proceed to step 8:
243 goes into 1496 6 times with a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 84116.0
If we take 1458 away from 1496, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
When dividing 380 by 243, we get 1 with a remainder of 137.
The next digit of our result is 1. 
Result so far: 84116.1
Subtracting 243 from 380 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 10:
The number 243 fits into 1370 5 times, leaving a remainder of 155.
Record the quotient 5 as the next digit in the result. 
Result so far: 84116.15
If we take 1215 away from 1370, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 11:
243 goes into 1550 6 times with a remainder of 92.
Put 6 as the next digit of the answer. 
Result so far: 84116.156
If we subtract 1458 from 1550, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 12:
243 goes into 920 3 times with a remainder of 191.
Put 3 as the next digit of the answer. 
Result so far: 84116.1563
Subtracting 729 from 920 leaves us with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Advancing to step 13:
If we divide 1910 by 243, we get 7 and a remainder of 209.
The number 7 becomes the next digit in our result. 
Result so far: 84116.15637
If we subtract 1701 from 1910, we get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 14:
243 goes into 2090 8 times with a remainder of 146.
Put 8 as the next digit of the answer. 
Result so far: 84116.156378
The remainder is 146 after subtracting 1944 from 2090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 15:
The number 243 fits into 1460 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 84116.1563786
Deduct 1458 from 1460 and we're left 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.

Advancing to step 16:
The number 243 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 84116.1563786
If we take 0 away from 20, we end up 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.

Our division results in 84116.1563786 with a remaining 2e-08.
