763261 divided by 20 
The aim is to understand the frequency of 20 in 763261.

On to step 1:
The number 20 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 20

Going ahead to step 2:
The number 20 fits into 76 3 times, leaving a remainder of 16.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 16 after subtracting 60 from 76.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 20

Advancing to step 3:
The number 20 fits into 163 8 times, leaving a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 38.0
The remainder is 3 after subtracting 160 from 163.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 20

Moving on to step 4:
32 divided by 20 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 381.0
If we take 20 away from 32, we end up with 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 20

On to step 5:
If we divide 126 by 20, we get 6 and a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 3816.0
If we subtract 120 from 126, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 20

Going ahead to step 6:
When dividing 61 by 20, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 38163.0
Subtracting 60 from 61 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
The number 20 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 38163.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 38163.05
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.

On to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 38163.05
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.

Step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 38163.05
If we take 0 away from 0, we end up 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.

Our division results in 38163.05 with a remaining 0.0.
