We're dividing 13872027 by 191 
The aim is to understand the frequency of 191 in 13872027.

Moving on to step 1:
191 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 191

Going ahead to step 2:
191 can be fit into 13 0 times, resulting in a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 191

Moving on to step 3:
138 divided by 191 is 0 with a remainder of 138.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 138, we end up with 138.
Fetch the next digit (7) from the dividend, attach it to 138 and continue: 1387 / 191

Advancing to step 4:
1387 divided by 191 is 7 with a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 1337 from 1387, we get 50.
Take the next digit (2) from the dividend and append it to 50, then repeat: 502 / 191

Advancing to step 5:
The number 191 fits into 502 2 times, leaving a remainder of 120.
Use 2 as the next digit of our solution. 
Result so far: 72.0
If we take 382 away from 502, we end up with 120.
Append the next digit (0) from the dividend to 120 and continue with: 1200 / 191

Going ahead to step 6:
191 goes into 1200 6 times with a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 726.0
Subtracting 1146 from 1200 leaves us with 54.
Include the next digit (2) from the dividend after 54, then repeat: 542 / 191

Let's proceed to step 7:
191 can be fit into 542 2 times, resulting in a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 7262.0
If we take 382 away from 542, we end up with 160.
Bring next digit (7) of the dividend behind the 160 and repeat the process: 1607 / 191

Step 8:
When dividing 1607 by 191, we get 8 with a remainder of 79.
Write down 8 as next digit of the result. 
Result so far: 72628.0
Deduct 1528 from 1607 and we're left 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.

On to step 9:
191 can be fit into 790 4 times, resulting in a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 72628.4
The remainder is 26 after subtracting 764 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
When dividing 260 by 191, we get 1 with a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 72628.41
If we take 191 away from 260, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 11:
The number 191 fits into 690 3 times, leaving a remainder of 117.
Record the quotient 3 as the next digit in the result. 
Result so far: 72628.413
The remainder is 117 after subtracting 573 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 12:
191 can be fit into 1170 6 times, resulting in a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 72628.4136
Subtracting 1146 from 1170 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
When dividing 240 by 191, we get 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 72628.41361
The remainder is 49 after subtracting 191 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 14:
191 goes into 490 2 times with a remainder of 108.
Record the quotient 2 as the next digit in the result. 
Result so far: 72628.413612
Subtract 382 from 490 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 15:
1080 divided by 191 is 5 with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 72628.4136125
If we take 955 away from 1080, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 16:
If we divide 1250 by 191, we get 6 and a remainder of 104.
Use 6 as the next digit of our solution. 
Result so far: 72628.41361256
Subtracting 1146 from 1250 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

After the division, we end up with 72628.41361256 and a remainder of 1.04e-07.
