18386630 ÷ 54 
The aim is to understand the frequency of 54 in 18386630.

Moving on to step 1:
1 divided by 54 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 54

Advancing to step 2:
If we divide 18 by 54, we get 0 and a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 54

Moving on to step 3:
54 goes into 183 3 times with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 162 from 183 to get 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 54

Step 4:
54 can be fit into 218 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we take 216 away from 218, we end up with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 54

Advancing to step 5:
54 can be fit into 26 0 times, resulting in a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 340.0
The remainder is 26 after subtracting 0 from 26.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 54

On to step 6:
When dividing 266 by 54, we get 4 with a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 3404.0
Subtract 216 from 266 to get 50.
Take the next digit (3) from the dividend and append it to 50, then repeat: 503 / 54

Advancing to step 7:
If we divide 503 by 54, we get 9 and a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 34049.0
Deduct 486 from 503 and we're left with 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 54

Going ahead to step 8:
If we divide 170 by 54, we get 3 and a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 340493.0
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
54 goes into 80 1 times with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 340493.1
Subtracting 54 from 80 leaves us 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.

Going ahead to step 10:
When dividing 260 by 54, we get 4 with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 340493.14
Deduct 216 from 260 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
440 divided by 54 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 340493.148
The remainder is 8 after subtracting 432 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
54 goes into 80 1 times with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 340493.1481
If we subtract 54 from 80, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 13:
If we divide 260 by 54, we get 4 and a remainder of 44.
The next digit of our result is 4. 
Result so far: 340493.14814
Subtracting 216 from 260 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 14:
The number 54 fits into 440 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 340493.148148
If we subtract 432 from 440, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 15:
54 can be fit into 80 1 times, resulting in a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 340493.1481481
Deduct 54 from 80 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.

Step 16:
54 goes into 260 4 times with a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 340493.14814814
The remainder is 44 after subtracting 216 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 340493.14814814 and a remainder of 4.4e-08.
