We divide 870756 by 54
The aim is to understand the frequency of 54 in 870756.

Step 1:
When dividing 8 by 54, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 54

Let's proceed to step 2:
When dividing 87 by 54, we get 1 with a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 54 from 87 and we're left with 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 54

Step 3:
If we divide 330 by 54, we get 6 and a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 324 from 330, we get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 54

On to step 4:
54 can be fit into 67 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 161.0
Deduct 54 from 67 and we're left with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 54

Moving on to step 5:
The number 54 fits into 135 2 times, leaving a remainder of 27.
Record the quotient 2 as the next digit in the result. 
Result so far: 1612.0
Subtracting 108 from 135 leaves us with 27.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 54

Moving on to step 6:
If we divide 276 by 54, we get 5 and a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 16125.0
If we take 270 away from 276, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
54 can be fit into 60 1 times, resulting in a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 16125.1
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
The number 54 fits into 60 1 times, leaving a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 16125.11
Deduct 54 from 60 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 16125.11 and a remainder of 0.006.
