19548740 ÷ 20 
The aim is to understand the frequency of 20 in 19548740.

Going ahead to step 1:
20 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 20

Going ahead to step 2:
The number 20 fits into 19 0 times, leaving a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 20

On to step 3:
When dividing 195 by 20, we get 9 with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 180 away from 195, we end up with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 20

Let's proceed to step 4:
When dividing 154 by 20, we get 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
The remainder is 14 after subtracting 140 from 154.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 20

Moving on to step 5:
20 can be fit into 148 7 times, resulting in a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 977.0
If we subtract 140 from 148, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 20

Moving on to step 6:
If we divide 87 by 20, we get 4 and a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 9774.0
If we take 80 away from 87, we end up with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 20

Let's proceed to step 7:
20 goes into 74 3 times with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 97743.0
Subtract 60 from 74 to get 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 20

Step 8:
If we divide 140 by 20, we get 7 and a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 977437.0
Subtracting 140 from 140 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 977437.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 977437.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 977437.0, with a leftover of 0.0.
