Let's divide 266378 by 54
The aim is to understand the frequency of 54 in 266378.

Going ahead to step 1:
54 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 54

Moving on to step 2:
If we divide 26 by 54, we get 0 and a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Fetch the next digit (6) from the dividend, attach it to 26 and continue: 266 / 54

On to step 3:
When dividing 266 by 54, we get 4 with a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 216 from 266 and we're left with 50.
Grab the next digit (3) from the dividend, add it to 50, then carry on: 503 / 54

Step 4:
54 goes into 503 9 times with a remainder of 17.
The next digit of our result is 9. 
Result so far: 49.0
Subtract 486 from 503 to get 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 54

Step 5:
When dividing 177 by 54, we get 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 493.0
If we take 162 away from 177, we end up with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 54

Advancing to step 6:
54 goes into 158 2 times with a remainder of 50.
The next digit of our result is 2. 
Result so far: 4932.0
Deduct 108 from 158 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
The number 54 fits into 500 9 times, leaving a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 4932.9
If we subtract 486 from 500, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
When dividing 140 by 54, we get 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 4932.92
If we subtract 108 from 140, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
When dividing 320 by 54, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 4932.925
Subtract 270 from 320 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
54 goes into 500 9 times with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 4932.9259
If we subtract 486 from 500, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
140 divided by 54 is 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 4932.92592
The remainder is 32 after subtracting 108 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
54 can be fit into 320 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 4932.925925
The remainder is 50 after subtracting 270 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
54 can be fit into 500 9 times, resulting in a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 4932.9259259
Subtract 486 from 500 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 14:
54 goes into 140 2 times with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 4932.92592592
Deduct 108 from 140 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 4932.92592592 with a remainder of 3.2e-08.
