We look at the division of 43843515 by 201 
The aim is to understand the frequency of 201 in 43843515.

Step 1:
201 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 201

On to step 2:
201 can be fit into 43 0 times, resulting in a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Fetch the next digit (8) from the dividend, attach it to 43 and continue: 438 / 201

Going ahead to step 3:
201 can be fit into 438 2 times, resulting in a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 402 away from 438, we end up with 36.
Grab the next digit (4) from the dividend, add it to 36, then carry on: 364 / 201

Going ahead to step 4:
364 divided by 201 is 1 with a remainder of 163.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 163 after subtracting 201 from 364.
Append the next digit (3) from the dividend to 163 and continue with: 1633 / 201

On to step 5:
When dividing 1633 by 201, we get 8 with a remainder of 25.
Write down 8 as next digit of the result. 
Result so far: 218.0
If we subtract 1608 from 1633, we get 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 201

Going ahead to step 6:
When dividing 255 by 201, we get 1 with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 2181.0
Subtract 201 from 255 to get 54.
Append the next digit (1) from the dividend to 54 and continue with: 541 / 201

Step 7:
201 goes into 541 2 times with a remainder of 139.
The number 2 becomes the next digit in our result. 
Result so far: 21812.0
Subtracting 402 from 541 leaves us with 139.
Grab the next digit (5) from the dividend, add it to 139, then carry on: 1395 / 201

Going ahead to step 8:
201 goes into 1395 6 times with a remainder of 189.
The next digit of our result is 6. 
Result so far: 218126.0
Subtract 1206 from 1395 to get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Let's proceed to step 9:
If we divide 1890 by 201, we get 9 and a remainder of 81.
Put 9 as the next digit of the answer. 
Result so far: 218126.9
If we take 1809 away from 1890, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 10:
When dividing 810 by 201, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 218126.94
If we subtract 804 from 810, 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.

Going ahead to step 11:
201 can be fit into 60 0 times, resulting in a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 218126.94
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
The number 201 fits into 600 2 times, leaving a remainder of 198.
Put 2 as the next digit of the answer. 
Result so far: 218126.9402
Subtracting 402 from 600 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 13:
The number 201 fits into 1980 9 times, leaving a remainder of 171.
Record the quotient 9 as the next digit in the result. 
Result so far: 218126.94029
Subtract 1809 from 1980 to get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 14:
If we divide 1710 by 201, we get 8 and a remainder of 102.
The number 8 becomes the next digit in our result. 
Result so far: 218126.940298
Subtracting 1608 from 1710 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 15:
The number 201 fits into 1020 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 218126.9402985
Subtract 1005 from 1020 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 16:
When dividing 150 by 201, we get 0 with a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 218126.9402985
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

In conclusion, the division gives 218126.9402985 with a balance of 1.5e-07.
