We look at the division of 1816437 by 542 
The aim is to understand the frequency of 542 in 1816437.

Let's proceed to step 1:
542 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 542

Moving on to step 2:
If we divide 18 by 542, we get 0 and a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 542

Step 3:
When dividing 181 by 542, we get 0 with a remainder of 181.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 181 and we're left with 181.
Append the next digit (6) from the dividend to 181 and continue with: 1816 / 542

Let's proceed to step 4:
When dividing 1816 by 542, we get 3 with a remainder of 190.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 1626 from 1816 and we're left with 190.
Grab the next digit (4) from the dividend, add it to 190, then carry on: 1904 / 542

Moving on to step 5:
1904 divided by 542 is 3 with a remainder of 278.
Write down 3 as next digit of the result. 
Result so far: 33.0
Deduct 1626 from 1904 and we're left with 278.
Bring next digit (3) of the dividend behind the 278 and repeat the process: 2783 / 542

Moving on to step 6:
When dividing 2783 by 542, we get 5 with a remainder of 73.
Put 5 as the next digit of the answer. 
Result so far: 335.0
Subtract 2710 from 2783 to get 73.
Include the next digit (7) from the dividend after 73, then repeat: 737 / 542

Let's proceed to step 7:
When dividing 737 by 542, we get 1 with a remainder of 195.
The next digit of our result is 1. 
Result so far: 3351.0
If we subtract 542 from 737, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 8:
If we divide 1950 by 542, we get 3 and a remainder of 324.
The number 3 becomes the next digit in our result. 
Result so far: 3351.3
If we subtract 1626 from 1950, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

On to step 9:
If we divide 3240 by 542, we get 5 and a remainder of 530.
Write down 5 as next digit of the result. 
Result so far: 3351.35
Deduct 2710 from 3240 and we're left with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 10:
542 can be fit into 5300 9 times, resulting in a remainder of 422.
The number 9 becomes the next digit in our result. 
Result so far: 3351.359
If we subtract 4878 from 5300, we get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Going ahead to step 11:
542 can be fit into 4220 7 times, resulting in a remainder of 426.
Put 7 as the next digit of the answer. 
Result so far: 3351.3597
If we subtract 3794 from 4220, we get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Moving on to step 12:
When dividing 4260 by 542, we get 7 with a remainder of 466.
Record the quotient 7 as the next digit in the result. 
Result so far: 3351.35977
Subtract 3794 from 4260 to get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

After the division, we end up with 3351.35977 and a remainder of 0.000466.
