We divide 815968 by 54
The aim is to understand the frequency of 54 in 815968.

On to step 1:
54 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 54

Step 2:
81 divided by 54 is 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 54 away from 81, we end up with 27.
Bring next digit (5) of the dividend behind the 27 and repeat the process: 275 / 54

On to step 3:
When dividing 275 by 54, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 270 away from 275, we end up with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 54

Going ahead to step 4:
54 goes into 59 1 times with a remainder of 5.
The next digit of our result is 1. 
Result so far: 151.0
Subtract 54 from 59 to get 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 54

Step 5:
56 divided by 54 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1511.0
Subtracting 54 from 56 leaves us with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 54

Let's proceed to step 6:
54 goes into 28 0 times with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 15110.0
Subtracting 0 from 28 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
If we divide 280 by 54, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 15110.5
Subtract 270 from 280 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
54 goes into 100 1 times with a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 15110.51
Subtract 54 from 100 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 9:
If we divide 460 by 54, we get 8 and a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 15110.518
If we subtract 432 from 460, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
The number 54 fits into 280 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 15110.5185
Deduct 270 from 280 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
If we divide 100 by 54, we get 1 and a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 15110.51851
Subtract 54 from 100 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
460 divided by 54 is 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 15110.518518
If we subtract 432 from 460, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 13:
54 goes into 280 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 15110.5185185
If we subtract 270 from 280, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
54 goes into 100 1 times with a remainder of 46.
The next digit of our result is 1. 
Result so far: 15110.51851851
If we take 54 away from 100, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

After the division, we end up with 15110.51851851 and a remainder of 4.6e-08.
