54748579 ÷ 19 
The aim is to understand the frequency of 19 in 54748579.

Advancing to step 1:
When dividing 5 by 19, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 19

Going ahead to step 2:
54 divided by 19 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 38 away from 54, we end up with 16.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 19

Let's proceed to step 3:
19 can be fit into 167 8 times, resulting in a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 152 from 167 and we're left with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 19

Moving on to step 4:
The number 19 fits into 154 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 288.0
The remainder is 2 after subtracting 152 from 154.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 19

Step 5:
19 goes into 28 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 2881.0
If we take 19 away from 28, we end up with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 19

Moving on to step 6:
When dividing 95 by 19, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 28815.0
The remainder is 0 after subtracting 95 from 95.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 19

On to step 7:
19 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 288150.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 19

On to step 8:
If we divide 79 by 19, we get 4 and a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 2881504.0
Subtracting 76 from 79 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
19 can be fit into 30 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 2881504.1
Deduct 19 from 30 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
When dividing 110 by 19, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 2881504.15
Subtract 95 from 110 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
19 can be fit into 150 7 times, resulting in a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 2881504.157
If we take 133 away from 150, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 12:
If we divide 170 by 19, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 2881504.1578
Subtracting 152 from 170 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 13:
When dividing 180 by 19, we get 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 2881504.15789
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 14:
19 goes into 90 4 times with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 2881504.157894
Subtracting 76 from 90 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 15:
When dividing 140 by 19, we get 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 2881504.1578947
If we subtract 133 from 140, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 16:
19 goes into 70 3 times with a remainder of 13.
The next digit of our result is 3. 
Result so far: 2881504.15789473
Subtract 57 from 70 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The quotient of the division is 2881504.15789473, and the remainder is 1.3e-08.
