We're dividing 51105955 by 181 
The aim is to understand the frequency of 181 in 51105955.

Moving on to step 1:
If we divide 5 by 181, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 181

Advancing to step 2:
181 can be fit into 51 0 times, resulting in a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Include the next digit (1) from the dividend after 51, then repeat: 511 / 181

Going ahead to step 3:
181 can be fit into 511 2 times, resulting in a remainder of 149.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 149 after subtracting 362 from 511.
Bring next digit (0) of the dividend behind the 149 and repeat the process: 1490 / 181

Moving on to step 4:
When dividing 1490 by 181, we get 8 with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtracting 1448 from 1490 leaves us with 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 181

Moving on to step 5:
When dividing 425 by 181, we get 2 with a remainder of 63.
Use 2 as the next digit of our solution. 
Result so far: 282.0
The remainder is 63 after subtracting 362 from 425.
Bring next digit (9) of the dividend behind the 63 and repeat the process: 639 / 181

Going ahead to step 6:
639 divided by 181 is 3 with a remainder of 96.
The number 3 becomes the next digit in our result. 
Result so far: 2823.0
If we take 543 away from 639, we end up with 96.
Grab the next digit (5) from the dividend, add it to 96, then carry on: 965 / 181

On to step 7:
When dividing 965 by 181, we get 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 28235.0
Deduct 905 from 965 and we're left with 60.
Grab the next digit (5) from the dividend, add it to 60, then carry on: 605 / 181

Advancing to step 8:
If we divide 605 by 181, we get 3 and a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 282353.0
The remainder is 62 after subtracting 543 from 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 9:
The number 181 fits into 620 3 times, leaving a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 282353.3
Subtract 543 from 620 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 10:
181 goes into 770 4 times with a remainder of 46.
The next digit of our result is 4. 
Result so far: 282353.34
If we take 724 away from 770, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 11:
When dividing 460 by 181, we get 2 with a remainder of 98.
Record the quotient 2 as the next digit in the result. 
Result so far: 282353.342
If we subtract 362 from 460, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 12:
980 divided by 181 is 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 282353.3425
The remainder is 75 after subtracting 905 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 13:
181 can be fit into 750 4 times, resulting in a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 282353.34254
If we subtract 724 from 750, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
The number 181 fits into 260 1 times, leaving a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 282353.342541
Subtracting 181 from 260 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 15:
The number 181 fits into 790 4 times, leaving a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 282353.3425414
If we take 724 away from 790, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 16:
181 goes into 660 3 times with a remainder of 117.
Record the quotient 3 as the next digit in the result. 
Result so far: 282353.34254143
The remainder is 117 after subtracting 543 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Our division results in 282353.34254143 with a remaining 1.17e-07.
