We divide 121396 by 54
The aim is to understand the frequency of 54 in 121396.

Moving on to step 1:
If we divide 1 by 54, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 54

Advancing to step 2:
If we divide 12 by 54, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 54

Moving on to step 3:
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: 2.0
If we take 108 away from 121, we end up with 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 54

Advancing to step 4:
54 can be fit into 133 2 times, resulting in a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtract 108 from 133 to get 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 54

Step 5:
The number 54 fits into 259 4 times, leaving a remainder of 43.
Put 4 as the next digit of the answer. 
Result so far: 224.0
If we take 216 away from 259, we end up with 43.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 54

Moving on to step 6:
If we divide 436 by 54, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 2248.0
If we subtract 432 from 436, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
40 divided by 54 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 2248.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
54 can be fit into 400 7 times, resulting in a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 2248.07
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
54 can be fit into 220 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 2248.074
If we take 216 away from 220, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
The number 54 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 2248.074
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
The number 54 fits into 400 7 times, leaving a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 2248.07407
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
220 divided by 54 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 2248.074074
If we take 216 away from 220, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
If we divide 40 by 54, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 2248.074074
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
54 can be fit into 400 7 times, resulting in a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 2248.07407407
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 2248.07407407, with a leftover of 2.2e-08.
