We're dividing 19843 by 54 
The aim is to understand the frequency of 54 in 19843.

Going ahead to step 1:
When dividing 1 by 54, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 54

Step 2:
When dividing 19 by 54, we get 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 54

Advancing to step 3:
The number 54 fits into 198 3 times, leaving a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 162 from 198 to get 36.
Fetch the next digit (4) from the dividend, attach it to 36 and continue: 364 / 54

On to step 4:
The number 54 fits into 364 6 times, leaving a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we subtract 324 from 364, we get 40.
Append the next digit (3) from the dividend to 40 and continue with: 403 / 54

Advancing to step 5:
54 can be fit into 403 7 times, resulting in a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 367.0
Deduct 378 from 403 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 6:
54 goes into 250 4 times with a remainder of 34.
The next digit of our result is 4. 
Result so far: 367.4
Subtract 216 from 250 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
54 goes into 340 6 times with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 367.46
Subtracting 324 from 340 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
When dividing 160 by 54, we get 2 with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 367.462
Deduct 108 from 160 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
If we divide 520 by 54, we get 9 and a remainder of 34.
The next digit of our result is 9. 
Result so far: 367.4629
Subtracting 486 from 520 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
54 goes into 340 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 367.46296
If we subtract 324 from 340, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
The number 54 fits into 160 2 times, leaving a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 367.462962
Subtract 108 from 160 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 12:
When dividing 520 by 54, we get 9 with a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 367.4629629
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 13:
The number 54 fits into 340 6 times, leaving a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 367.46296296
If we subtract 324 from 340, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 367.46296296, and the remainder is 1.6e-08.
