75192842 divided by 181 
The aim is to understand the frequency of 181 in 75192842.

On to step 1:
If we divide 7 by 181, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 181

Moving on to step 2:
When dividing 75 by 181, we get 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Grab the next digit (1) from the dividend, add it to 75, then carry on: 751 / 181

Moving on to step 3:
If we divide 751 by 181, we get 4 and a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 724 from 751 leaves us with 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 181

Step 4:
181 can be fit into 279 1 times, resulting in a remainder of 98.
The next digit of our result is 1. 
Result so far: 41.0
Subtract 181 from 279 to get 98.
Grab the next digit (2) from the dividend, add it to 98, then carry on: 982 / 181

On to step 5:
When dividing 982 by 181, we get 5 with a remainder of 77.
Write down 5 as next digit of the result. 
Result so far: 415.0
If we subtract 905 from 982, we get 77.
Take the next digit (8) from the dividend and append it to 77, then repeat: 778 / 181

Let's proceed to step 6:
When dividing 778 by 181, we get 4 with a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 4154.0
Subtracting 724 from 778 leaves us with 54.
Grab the next digit (4) from the dividend, add it to 54, then carry on: 544 / 181

Step 7:
181 goes into 544 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 41543.0
If we take 543 away from 544, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 181

Advancing to step 8:
When dividing 12 by 181, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 415430.0
Subtracting 0 from 12 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
181 can be fit into 120 0 times, resulting in a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 415430.0
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 10:
When dividing 1200 by 181, we get 6 with a remainder of 114.
Write down 6 as next digit of the result. 
Result so far: 415430.06
If we subtract 1086 from 1200, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 11:
181 can be fit into 1140 6 times, resulting in a remainder of 54.
Write down 6 as next digit of the result. 
Result so far: 415430.066
The remainder is 54 after subtracting 1086 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 415430.066 with a remaining 0.0054.
