We divide 53063851 by 20
The aim is to understand the frequency of 20 in 53063851.

Moving on to step 1:
When dividing 5 by 20, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 20

Step 2:
If we divide 53 by 20, we get 2 and a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 40 from 53, we get 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 20

On to step 3:
When dividing 130 by 20, we get 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 26.0
Deduct 120 from 130 and we're left with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 20

On to step 4:
20 goes into 106 5 times with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 265.0
Subtract 100 from 106 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 20

On to step 5:
The number 20 fits into 63 3 times, leaving a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 2653.0
Subtracting 60 from 63 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 20

Step 6:
20 goes into 38 1 times with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 26531.0
Subtract 20 from 38 to get 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 20

Going ahead to step 7:
20 can be fit into 185 9 times, resulting in a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 265319.0
Subtract 180 from 185 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 20

Moving on to step 8:
The number 20 fits into 51 2 times, leaving a remainder of 11.
The next digit of our result is 2. 
Result so far: 2653192.0
Deduct 40 from 51 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.

Let's proceed to step 9:
20 goes into 110 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 2653192.5
Subtracting 100 from 110 leaves us 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.

Moving on to step 10:
When dividing 100 by 20, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 2653192.55
The remainder is 0 after subtracting 100 from 100.
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 2653192.55, with a leftover of 0.0.
