55240754 ÷ 138 
The aim is to understand the frequency of 138 in 55240754.

Step 1:
138 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 138

Step 2:
138 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Fetch the next digit (2) from the dividend, attach it to 55 and continue: 552 / 138

Going ahead to step 3:
138 can be fit into 552 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 552 from 552, we get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 138

Advancing to step 4:
138 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 40.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 138

Going ahead to step 5:
If we divide 40 by 138, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 400.0
Subtract 0 from 40 to get 40.
Bring next digit (7) of the dividend behind the 40 and repeat the process: 407 / 138

Going ahead to step 6:
407 divided by 138 is 2 with a remainder of 131.
Put 2 as the next digit of the answer. 
Result so far: 4002.0
Deduct 276 from 407 and we're left with 131.
Include the next digit (5) from the dividend after 131, then repeat: 1315 / 138

Step 7:
If we divide 1315 by 138, we get 9 and a remainder of 73.
The next digit of our result is 9. 
Result so far: 40029.0
Subtract 1242 from 1315 to get 73.
Take the next digit (4) from the dividend and append it to 73, then repeat: 734 / 138

Moving on to step 8:
If we divide 734 by 138, we get 5 and a remainder of 44.
Write down 5 as next digit of the result. 
Result so far: 400295.0
If we subtract 690 from 734, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
When dividing 440 by 138, we get 3 with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 400295.3
Deduct 414 from 440 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 10:
138 goes into 260 1 times with a remainder of 122.
Write down 1 as next digit of the result. 
Result so far: 400295.31
Subtract 138 from 260 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 11:
138 goes into 1220 8 times with a remainder of 116.
The number 8 becomes the next digit in our result. 
Result so far: 400295.318
Deduct 1104 from 1220 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 12:
If we divide 1160 by 138, we get 8 and a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 400295.3188
If we subtract 1104 from 1160, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 400295.3188 with a remainder of 0.00056.
