Let's divide 535077 by 20
The aim is to understand the frequency of 20 in 535077.

Going ahead to step 1:
If we divide 5 by 20, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 20

On to step 2:
53 divided by 20 is 2 with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 40 from 53 leaves us with 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 20

On to step 3:
When dividing 135 by 20, we get 6 with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
The remainder is 15 after subtracting 120 from 135.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 20

Moving on to step 4:
150 divided by 20 is 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 267.0
Deduct 140 from 150 and we're left with 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 20

Moving on to step 5:
20 goes into 107 5 times with a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 2675.0
Deduct 100 from 107 and we're left with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 20

Moving on to step 6:
The number 20 fits into 77 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 26753.0
If we subtract 60 from 77, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
The number 20 fits into 170 8 times, leaving a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 26753.8
Subtract 160 from 170 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
100 divided by 20 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 26753.85
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.

Going ahead to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 26753.85
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 26753.85
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 quotient of the division is 26753.85, and the remainder is 0.0.
