We divide 830547 by 20
The aim is to understand the frequency of 20 in 830547.

On to step 1:
When dividing 8 by 20, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 20

On to step 2:
The number 20 fits into 83 4 times, leaving a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 80 from 83 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 20

Step 3:
20 goes into 30 1 times with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 41.0
If we subtract 20 from 30, we get 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 20

Going ahead to step 4:
The number 20 fits into 105 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 415.0
Deduct 100 from 105 and we're left with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 20

Going ahead to step 5:
If we divide 54 by 20, we get 2 and a remainder of 14.
The next digit of our result is 2. 
Result so far: 4152.0
If we take 40 away from 54, we end up with 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 20

Let's proceed to step 6:
147 divided by 20 is 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 41527.0
Subtract 140 from 147 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
20 goes into 70 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 41527.3
The remainder is 10 after subtracting 60 from 70.
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:
20 goes into 100 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 41527.35
Deduct 100 from 100 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.

Going ahead to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 41527.35
The remainder is 0 after subtracting 0 from 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:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 41527.35
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.

In conclusion, the division gives 41527.35 with a balance of 0.0.
