356674 ÷ 54 
The aim is to understand the frequency of 54 in 356674.

Let's proceed to step 1:
If we divide 3 by 54, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 54

Advancing to step 2:
54 can be fit into 35 0 times, resulting in a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Include the next digit (6) from the dividend after 35, then repeat: 356 / 54

Advancing to step 3:
The number 54 fits into 356 6 times, leaving a remainder of 32.
The next digit of our result is 6. 
Result so far: 6.0
If we take 324 away from 356, we end up with 32.
Fetch the next digit (6) from the dividend, attach it to 32 and continue: 326 / 54

Moving on to step 4:
When dividing 326 by 54, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Subtract 324 from 326 to get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 54

On to step 5:
If we divide 27 by 54, we get 0 and a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 660.0
Subtracting 0 from 27 leaves us with 27.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 54

On to step 6:
The number 54 fits into 274 5 times, leaving a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 6605.0
Subtracting 270 from 274 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
40 divided by 54 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 6605.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
54 can be fit into 400 7 times, resulting in a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 6605.07
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
220 divided by 54 is 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 6605.074
Subtract 216 from 220 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
If we divide 40 by 54, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 6605.074
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
The number 54 fits into 400 7 times, leaving a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 6605.07407
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
If we divide 220 by 54, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 6605.074074
Subtracting 216 from 220 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
When dividing 40 by 54, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 6605.074074
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
54 can be fit into 400 7 times, resulting in a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 6605.07407407
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 6605.07407407, with a leftover of 2.2e-08.
