We're dividing 7381 by 54 
The aim is to understand the frequency of 54 in 7381.

Advancing to step 1:
7 divided by 54 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 54

Let's proceed to step 2:
If we divide 73 by 54, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 54 away from 73, we end up with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 54

Let's proceed to step 3:
The number 54 fits into 198 3 times, leaving a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 162 from 198, we get 36.
Include the next digit (1) from the dividend after 36, then repeat: 361 / 54

Going ahead to step 4:
When dividing 361 by 54, we get 6 with a remainder of 37.
Write down 6 as next digit of the result. 
Result so far: 136.0
Deduct 324 from 361 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 5:
The number 54 fits into 370 6 times, leaving a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.6
The remainder is 46 after subtracting 324 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 6:
If we divide 460 by 54, we get 8 and a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 136.68
The remainder is 28 after subtracting 432 from 460.
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 7:
If we divide 280 by 54, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 136.685
The remainder is 10 after subtracting 270 from 280.
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:
The number 54 fits into 100 1 times, leaving a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 136.6851
The remainder is 46 after subtracting 54 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
The number 54 fits into 460 8 times, leaving a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 136.68518
Deduct 432 from 460 and we're left 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.

Moving on to step 10:
If we divide 280 by 54, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 136.685185
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.

On to step 11:
54 goes into 100 1 times with a remainder of 46.
The next digit of our result is 1. 
Result so far: 136.6851851
Deduct 54 from 100 and we're left 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.

On to step 12:
The number 54 fits into 460 8 times, leaving a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 136.68518518
Subtract 432 from 460 to 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.

The final outcome is 136.68518518, with a leftover of 2.8e-08.
