687013 divided by 54 
The aim is to understand the frequency of 54 in 687013.

Advancing to step 1:
54 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 54

Moving on to step 2:
If we divide 68 by 54, we get 1 and a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 54 from 68 and we're left with 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 54

On to step 3:
54 can be fit into 147 2 times, resulting in a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 108 from 147 leaves us with 39.
Fetch the next digit (0) from the dividend, attach it to 39 and continue: 390 / 54

Step 4:
54 goes into 390 7 times with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 127.0
If we subtract 378 from 390, we get 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 54

On to step 5:
The number 54 fits into 121 2 times, leaving a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 1272.0
If we take 108 away from 121, we end up with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 54

Advancing to step 6:
The number 54 fits into 133 2 times, leaving a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 12722.0
If we take 108 away from 133, we end up 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.

Moving on to step 7:
When dividing 250 by 54, we get 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 12722.4
If we subtract 216 from 250, we 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.

Let's proceed to step 8:
340 divided by 54 is 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 12722.46
Deduct 324 from 340 and we're left 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 9:
54 goes into 160 2 times with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 12722.462
The remainder is 52 after subtracting 108 from 160.
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 10:
520 divided by 54 is 9 with a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 12722.4629
If we subtract 486 from 520, we 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 11:
340 divided by 54 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 12722.46296
If we take 324 away from 340, we end up 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.

Moving on to step 12:
When dividing 160 by 54, we get 2 with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 12722.462962
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.

Moving on to step 13:
54 can be fit into 520 9 times, resulting in a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 12722.4629629
If we subtract 486 from 520, we 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.

Advancing to step 14:
If we divide 340 by 54, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 12722.46296296
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.

After the division, we end up with 12722.46296296 and a remainder of 1.6e-08.
