We look at the division of 81109650 by 185 
The aim is to understand the frequency of 185 in 81109650.

On to step 1:
8 divided by 185 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 185

Let's proceed to step 2:
If we divide 81 by 185, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Include the next digit (1) from the dividend after 81, then repeat: 811 / 185

Moving on to step 3:
The number 185 fits into 811 4 times, leaving a remainder of 71.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 71 after subtracting 740 from 811.
Fetch the next digit (0) from the dividend, attach it to 71 and continue: 710 / 185

Going ahead to step 4:
710 divided by 185 is 3 with a remainder of 155.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtracting 555 from 710 leaves us with 155.
Include the next digit (9) from the dividend after 155, then repeat: 1559 / 185

Step 5:
185 can be fit into 1559 8 times, resulting in a remainder of 79.
Use 8 as the next digit of our solution. 
Result so far: 438.0
Deduct 1480 from 1559 and we're left with 79.
Grab the next digit (6) from the dividend, add it to 79, then carry on: 796 / 185

Moving on to step 6:
The number 185 fits into 796 4 times, leaving a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 4384.0
Deduct 740 from 796 and we're left with 56.
Grab the next digit (5) from the dividend, add it to 56, then carry on: 565 / 185

Moving on to step 7:
The number 185 fits into 565 3 times, leaving a remainder of 10.
The next digit of our result is 3. 
Result so far: 43843.0
If we subtract 555 from 565, we get 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 185

Moving on to step 8:
100 divided by 185 is 0 with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 438430.0
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 9:
185 can be fit into 1000 5 times, resulting in a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 438430.5
Subtract 925 from 1000 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 10:
If we divide 750 by 185, we get 4 and a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 438430.54
If we subtract 740 from 750, 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.

Step 11:
If we divide 100 by 185, we get 0 and a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 438430.54
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 12:
If we divide 1000 by 185, we get 5 and a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 438430.5405
If we take 925 away from 1000, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 13:
If we divide 750 by 185, we get 4 and a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 438430.54054
Subtract 740 from 750 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.

Let's proceed to step 14:
100 divided by 185 is 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 438430.54054
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 15:
185 goes into 1000 5 times with a remainder of 75.
The next digit of our result is 5. 
Result so far: 438430.5405405
The remainder is 75 after subtracting 925 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 16:
When dividing 750 by 185, we get 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 438430.54054054
Subtract 740 from 750 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.

Our division results in 438430.54054054 with a remaining 1e-08.
