We look at the division of 819598 by 54 
The aim is to understand the frequency of 54 in 819598.

Step 1:
If we divide 8 by 54, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
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

Let's proceed to step 2:
When dividing 81 by 54, we get 1 with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 54 from 81 leaves us with 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 54

On to step 3:
279 divided by 54 is 5 with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 270 away from 279, we end up with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 54

Advancing to step 4:
95 divided by 54 is 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 151.0
Subtract 54 from 95 to get 41.
Take the next digit (9) from the dividend and append it to 41, then repeat: 419 / 54

Advancing to step 5:
54 goes into 419 7 times with a remainder of 41.
The next digit of our result is 7. 
Result so far: 1517.0
The remainder is 41 after subtracting 378 from 419.
Take the next digit (8) from the dividend and append it to 41, then repeat: 418 / 54

Step 6:
54 goes into 418 7 times with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 15177.0
Deduct 378 from 418 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
If we divide 400 by 54, we get 7 and a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 15177.7
Deduct 378 from 400 and we're left 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.

Going ahead to step 8:
54 can be fit into 220 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 15177.74
Subtracting 216 from 220 leaves us 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.

Let's proceed to step 9:
54 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 15177.74
If we subtract 0 from 40, we 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.

Let's proceed to step 10:
If we divide 400 by 54, we get 7 and a remainder of 22.
The next digit of our result is 7. 
Result so far: 15177.7407
Deduct 378 from 400 and we're left 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.

On to step 11:
If we divide 220 by 54, we get 4 and a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 15177.74074
Subtract 216 from 220 to 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.

Going ahead to step 12:
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: 15177.74074
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 13:
When dividing 400 by 54, we get 7 with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 15177.7407407
Subtracting 378 from 400 leaves us 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 14:
When dividing 220 by 54, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 15177.74074074
The remainder is 4 after subtracting 216 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 15177.74074074, and the remainder is 4e-09.
