We divide 841949 by 20
The aim is to understand the frequency of 20 in 841949.

Let's proceed to step 1:
The number 20 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 20

Let's proceed to step 2:
20 goes into 84 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 80 away from 84, we end up with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 20

Moving on to step 3:
If we divide 41 by 20, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Deduct 40 from 41 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 20

Advancing to step 4:
The number 20 fits into 19 0 times, leaving a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 420.0
Subtracting 0 from 19 leaves us with 19.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 20

Advancing to step 5:
20 goes into 194 9 times with a remainder of 14.
The next digit of our result is 9. 
Result so far: 4209.0
The remainder is 14 after subtracting 180 from 194.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 20

Moving on to step 6:
If we divide 149 by 20, we get 7 and a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 42097.0
Subtracting 140 from 149 leaves us 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.

Let's proceed to step 7:
If we divide 90 by 20, we get 4 and a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 42097.4
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:
When dividing 100 by 20, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 42097.45
Subtracting 100 from 100 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.

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: 42097.45
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.

Going ahead to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 42097.45
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.

The final result is 42097.45 with a remainder of 0.0.
