We divide 953980 by 20
The aim is to understand the frequency of 20 in 953980.

Step 1:
20 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 20

On to step 2:
20 goes into 95 4 times with a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 80 from 95 leaves us with 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 20

Step 3:
20 goes into 153 7 times with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 47.0
Subtracting 140 from 153 leaves us with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 20

Going ahead to step 4:
The number 20 fits into 139 6 times, leaving a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 476.0
Subtracting 120 from 139 leaves us with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 20

Let's proceed to step 5:
20 can be fit into 198 9 times, resulting in a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 4769.0
If we take 180 away from 198, we end up with 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 20

On to step 6:
20 can be fit into 180 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 47699.0
Subtracting 180 from 180 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 7:
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: 47699.0
If we subtract 0 from 0, we 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.

Let's proceed to step 8:
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: 47699.0
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.

The final result is 47699.0 with a remainder of 0.0.
