We divide 773749 by 20
The aim is to understand the frequency of 20 in 773749.

Step 1:
When dividing 7 by 20, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 20

On to step 2:
20 goes into 77 3 times with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 60 from 77, we get 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 20

Going ahead to step 3:
If we divide 173 by 20, we get 8 and a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 38.0
Deduct 160 from 173 and we're left with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 20

On to step 4:
When dividing 137 by 20, we get 6 with a remainder of 17.
The next digit of our result is 6. 
Result so far: 386.0
If we subtract 120 from 137, we get 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 20

Moving on to step 5:
The number 20 fits into 174 8 times, leaving a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 3868.0
Subtracting 160 from 174 leaves us with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 20

Moving on to step 6:
149 divided by 20 is 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 38687.0
If we take 140 away from 149, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
If we divide 90 by 20, we get 4 and a remainder of 10.
The next digit of our result is 4. 
Result so far: 38687.4
Deduct 80 from 90 and we're left 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.

Let's proceed to step 8:
100 divided by 20 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 38687.45
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:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 38687.45
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.

Moving on to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 38687.45
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.

The final result is 38687.45 with a remainder of 0.0.
