We look at the division of 343694 by 54 
The aim is to understand the frequency of 54 in 343694.

Let's proceed to step 1:
When dividing 3 by 54, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 54

Advancing to step 2:
34 divided by 54 is 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 54

On to step 3:
343 divided by 54 is 6 with a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 324 from 343, we get 19.
Include the next digit (6) from the dividend after 19, then repeat: 196 / 54

Advancing to step 4:
54 can be fit into 196 3 times, resulting in a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtracting 162 from 196 leaves us with 34.
Bring next digit (9) of the dividend behind the 34 and repeat the process: 349 / 54

Let's proceed to step 5:
When dividing 349 by 54, we get 6 with a remainder of 25.
The next digit of our result is 6. 
Result so far: 636.0
Subtract 324 from 349 to get 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 54

Moving on to step 6:
The number 54 fits into 254 4 times, leaving a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 6364.0
Deduct 216 from 254 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
54 goes into 380 7 times with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 6364.7
Deduct 378 from 380 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
54 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 6364.7
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
54 can be fit into 200 3 times, resulting in a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 6364.703
If we take 162 away from 200, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
If we divide 380 by 54, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 6364.7037
Subtracting 378 from 380 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
54 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 6364.7037
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
54 goes into 200 3 times with a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 6364.703703
Subtract 162 from 200 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 13:
If we divide 380 by 54, we get 7 and a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 6364.7037037
Subtracting 378 from 380 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
If we divide 20 by 54, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 6364.7037037
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 6364.7037037 and a remainder of 2e-08.
