We divide 39353635 by 181
The aim is to understand the frequency of 181 in 39353635.

Let's proceed to step 1:
181 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 181

Moving on to step 2:
181 goes into 39 0 times with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 181

Step 3:
The number 181 fits into 393 2 times, leaving a remainder of 31.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 362 from 393 leaves us with 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 181

Moving on to step 4:
181 can be fit into 315 1 times, resulting in a remainder of 134.
The next digit of our result is 1. 
Result so far: 21.0
Subtract 181 from 315 to get 134.
Include the next digit (3) from the dividend after 134, then repeat: 1343 / 181

Going ahead to step 5:
If we divide 1343 by 181, we get 7 and a remainder of 76.
Put 7 as the next digit of the answer. 
Result so far: 217.0
If we subtract 1267 from 1343, we get 76.
Include the next digit (6) from the dividend after 76, then repeat: 766 / 181

On to step 6:
766 divided by 181 is 4 with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 2174.0
Deduct 724 from 766 and we're left with 42.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 181

Step 7:
If we divide 423 by 181, we get 2 and a remainder of 61.
Use 2 as the next digit of our solution. 
Result so far: 21742.0
If we subtract 362 from 423, we get 61.
Take the next digit (5) from the dividend and append it to 61, then repeat: 615 / 181

Let's proceed to step 8:
If we divide 615 by 181, we get 3 and a remainder of 72.
Write down 3 as next digit of the result. 
Result so far: 217423.0
The remainder is 72 after subtracting 543 from 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 9:
181 goes into 720 3 times with a remainder of 177.
The next digit of our result is 3. 
Result so far: 217423.3
If we subtract 543 from 720, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Let's proceed to step 10:
When dividing 1770 by 181, we get 9 with a remainder of 141.
Record the quotient 9 as the next digit in the result. 
Result so far: 217423.39
Subtracting 1629 from 1770 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Let's proceed to step 11:
If we divide 1410 by 181, we get 7 and a remainder of 143.
Use 7 as the next digit of our solution. 
Result so far: 217423.397
If we take 1267 away from 1410, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Going ahead to step 12:
181 goes into 1430 7 times with a remainder of 163.
Put 7 as the next digit of the answer. 
Result so far: 217423.3977
Subtracting 1267 from 1430 leaves us with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

The final result is 217423.3977 with a remainder of 0.00163.
