We look at the division of 71544270 by 548 
The aim is to understand the frequency of 548 in 71544270.

Advancing to step 1:
The number 548 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 548

Going ahead to step 2:
If we divide 71 by 548, we get 0 and a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Bring next digit (5) of the dividend behind the 71 and repeat the process: 715 / 548

Step 3:
If we divide 715 by 548, we get 1 and a remainder of 167.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 548 from 715 and we're left with 167.
Bring next digit (4) of the dividend behind the 167 and repeat the process: 1674 / 548

Moving on to step 4:
548 goes into 1674 3 times with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 30 after subtracting 1644 from 1674.
Include the next digit (4) from the dividend after 30, then repeat: 304 / 548

Moving on to step 5:
When dividing 304 by 548, we get 0 with a remainder of 304.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
The remainder is 304 after subtracting 0 from 304.
Include the next digit (2) from the dividend after 304, then repeat: 3042 / 548

Step 6:
When dividing 3042 by 548, we get 5 with a remainder of 302.
Record the quotient 5 as the next digit in the result. 
Result so far: 1305.0
Deduct 2740 from 3042 and we're left with 302.
Bring next digit (7) of the dividend behind the 302 and repeat the process: 3027 / 548

Advancing to step 7:
If we divide 3027 by 548, we get 5 and a remainder of 287.
The number 5 becomes the next digit in our result. 
Result so far: 13055.0
The remainder is 287 after subtracting 2740 from 3027.
Take the next digit (0) from the dividend and append it to 287, then repeat: 2870 / 548

Step 8:
2870 divided by 548 is 5 with a remainder of 130.
The next digit of our result is 5. 
Result so far: 130555.0
Subtract 2740 from 2870 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 9:
If we divide 1300 by 548, we get 2 and a remainder of 204.
Use 2 as the next digit of our solution. 
Result so far: 130555.2
Subtracting 1096 from 1300 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 10:
2040 divided by 548 is 3 with a remainder of 396.
The number 3 becomes the next digit in our result. 
Result so far: 130555.23
Subtract 1644 from 2040 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 11:
548 goes into 3960 7 times with a remainder of 124.
The next digit of our result is 7. 
Result so far: 130555.237
Subtract 3836 from 3960 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 12:
548 goes into 1240 2 times with a remainder of 144.
Write down 2 as next digit of the result. 
Result so far: 130555.2372
Subtracting 1096 from 1240 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 13:
If we divide 1440 by 548, we get 2 and a remainder of 344.
The next digit of our result is 2. 
Result so far: 130555.23722
Subtracting 1096 from 1440 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Our division results in 130555.23722 with a remaining 0.000344.
