143489 divided by 54 
The aim is to understand the frequency of 54 in 143489.

Going ahead to step 1:
When dividing 1 by 54, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 54

Moving on to step 2:
When dividing 14 by 54, we get 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 54

Step 3:
When dividing 143 by 54, we get 2 with a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 108 from 143 leaves us with 35.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 54

Let's proceed to step 4:
If we divide 354 by 54, we get 6 and a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 26.0
If we take 324 away from 354, we end up with 30.
Grab the next digit (8) from the dividend, add it to 30, then carry on: 308 / 54

Moving on to step 5:
If we divide 308 by 54, we get 5 and a remainder of 38.
The next digit of our result is 5. 
Result so far: 265.0
Deduct 270 from 308 and we're left with 38.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 54

Step 6:
54 goes into 389 7 times with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 2657.0
Subtracting 378 from 389 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
When dividing 110 by 54, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2657.2
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
When dividing 20 by 54, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2657.2
Deduct 0 from 20 and we're left 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.

On to step 9:
The number 54 fits into 200 3 times, leaving a remainder of 38.
The next digit of our result is 3. 
Result so far: 2657.203
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.

On to step 10:
54 can be fit into 380 7 times, resulting in a remainder of 2.
The next digit of our result is 7. 
Result so far: 2657.2037
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.

Let's proceed to step 11:
When dividing 20 by 54, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 2657.2037
Deduct 0 from 20 and we're left 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.

Step 12:
If we divide 200 by 54, we get 3 and a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 2657.203703
Deduct 162 from 200 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.

On to step 13:
When dividing 380 by 54, we get 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 2657.2037037
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
The number 54 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 2657.2037037
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.

In conclusion, the division gives 2657.2037037 with a balance of 2e-08.
