13581425 ÷ 301 
The aim is to understand the frequency of 301 in 13581425.

Step 1:
301 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
Subtract 0 from 1 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 301

Moving on to step 2:
301 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 301

Advancing to step 3:
301 goes into 135 0 times with a remainder of 135.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 135 leaves us with 135.
Fetch the next digit (8) from the dividend, attach it to 135 and continue: 1358 / 301

Let's proceed to step 4:
If we divide 1358 by 301, we get 4 and a remainder of 154.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 154 after subtracting 1204 from 1358.
Bring next digit (1) of the dividend behind the 154 and repeat the process: 1541 / 301

On to step 5:
If we divide 1541 by 301, we get 5 and a remainder of 36.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtracting 1505 from 1541 leaves us with 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 301

Step 6:
When dividing 364 by 301, we get 1 with a remainder of 63.
Put 1 as the next digit of the answer. 
Result so far: 451.0
Subtracting 301 from 364 leaves us with 63.
Grab the next digit (2) from the dividend, add it to 63, then carry on: 632 / 301

Let's proceed to step 7:
301 goes into 632 2 times with a remainder of 30.
The next digit of our result is 2. 
Result so far: 4512.0
If we subtract 602 from 632, we get 30.
Fetch the next digit (5) from the dividend, attach it to 30 and continue: 305 / 301

Advancing to step 8:
If we divide 305 by 301, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 45121.0
If we take 301 away from 305, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
40 divided by 301 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 45121.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
When dividing 400 by 301, we get 1 with a remainder of 99.
The next digit of our result is 1. 
Result so far: 45121.01
Subtract 301 from 400 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 11:
301 can be fit into 990 3 times, resulting in a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 45121.013
Subtracting 903 from 990 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 12:
301 goes into 870 2 times with a remainder of 268.
Record the quotient 2 as the next digit in the result. 
Result so far: 45121.0132
Deduct 602 from 870 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 13:
301 goes into 2680 8 times with a remainder of 272.
Write down 8 as next digit of the result. 
Result so far: 45121.01328
If we take 2408 away from 2680, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 14:
2720 divided by 301 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 45121.013289
The remainder is 11 after subtracting 2709 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 15:
If we divide 110 by 301, we get 0 and a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 45121.013289
If we take 0 away from 110, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 16:
301 can be fit into 1100 3 times, resulting in a remainder of 197.
Use 3 as the next digit of our solution. 
Result so far: 45121.01328903
The remainder is 197 after subtracting 903 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

The quotient of the division is 45121.01328903, and the remainder is 1.97e-07.
