636938 divided by 54 
The aim is to understand the frequency of 54 in 636938.

Step 1:
6 divided by 54 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 54

Moving on to step 2:
If we divide 63 by 54, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 54 from 63, we get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 54

Let's proceed to step 3:
96 divided by 54 is 1 with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 54 from 96 leaves us with 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 54

Let's proceed to step 4:
54 goes into 429 7 times with a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 117.0
If we subtract 378 from 429, we get 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 54

On to step 5:
54 goes into 513 9 times with a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 1179.0
If we subtract 486 from 513, we get 27.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 54

Moving on to step 6:
54 goes into 278 5 times with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 11795.0
The remainder is 8 after subtracting 270 from 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
54 goes into 80 1 times with a remainder of 26.
The next digit of our result is 1. 
Result so far: 11795.1
Deduct 54 from 80 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
When dividing 260 by 54, we get 4 with a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 11795.14
If we subtract 216 from 260, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
When dividing 440 by 54, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 11795.148
If we take 432 away from 440, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
54 can be fit into 80 1 times, resulting in a remainder of 26.
The next digit of our result is 1. 
Result so far: 11795.1481
If we take 54 away from 80, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
If we divide 260 by 54, we get 4 and a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 11795.14814
Subtract 216 from 260 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 12:
When dividing 440 by 54, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 11795.148148
If we subtract 432 from 440, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
If we divide 80 by 54, we get 1 and a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 11795.1481481
Subtract 54 from 80 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 14:
54 goes into 260 4 times with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 11795.14814814
Deduct 216 from 260 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 11795.14814814 and a remainder of 4.4e-08.
