12877141 ÷ 301 
The aim is to understand the frequency of 301 in 12877141.

Moving on to step 1:
1 divided by 301 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 301

Moving on to step 2:
301 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 301

Advancing to step 3:
If we divide 128 by 301, we get 0 and a remainder of 128.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 128, we get 128.
Fetch the next digit (7) from the dividend, attach it to 128 and continue: 1287 / 301

Going ahead to step 4:
1287 divided by 301 is 4 with a remainder of 83.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 1204 away from 1287, we end up with 83.
Include the next digit (7) from the dividend after 83, then repeat: 837 / 301

Moving on to step 5:
When dividing 837 by 301, we get 2 with a remainder of 235.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we subtract 602 from 837, we get 235.
Fetch the next digit (1) from the dividend, attach it to 235 and continue: 2351 / 301

Let's proceed to step 6:
If we divide 2351 by 301, we get 7 and a remainder of 244.
The next digit of our result is 7. 
Result so far: 427.0
Deduct 2107 from 2351 and we're left with 244.
Append the next digit (4) from the dividend to 244 and continue with: 2444 / 301

Let's proceed to step 7:
301 can be fit into 2444 8 times, resulting in a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 4278.0
Subtracting 2408 from 2444 leaves us with 36.
Include the next digit (1) from the dividend after 36, then repeat: 361 / 301

Let's proceed to step 8:
301 goes into 361 1 times with a remainder of 60.
Put 1 as the next digit of the answer. 
Result so far: 42781.0
If we take 301 away from 361, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
301 can be fit into 600 1 times, resulting in a remainder of 299.
Put 1 as the next digit of the answer. 
Result so far: 42781.1
If we take 301 away from 600, we end up with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Moving on to step 10:
If we divide 2990 by 301, we get 9 and a remainder of 281.
Record the quotient 9 as the next digit in the result. 
Result so far: 42781.19
Subtract 2709 from 2990 to get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

On to step 11:
301 can be fit into 2810 9 times, resulting in a remainder of 101.
Write down 9 as next digit of the result. 
Result so far: 42781.199
Subtract 2709 from 2810 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Our division results in 42781.199 with a remaining 0.0101.
