We divide 383440 by 20
The aim is to understand the frequency of 20 in 383440.

Advancing to step 1:
The number 20 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 20

Going ahead to step 2:
38 divided by 20 is 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 18 after subtracting 20 from 38.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 20

Moving on to step 3:
When dividing 183 by 20, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 180 from 183 to get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 20

Advancing to step 4:
When dividing 34 by 20, we get 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 191.0
Subtracting 20 from 34 leaves us with 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 20

Moving on to step 5:
When dividing 144 by 20, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 1917.0
Deduct 140 from 144 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 20

Step 6:
If we divide 40 by 20, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 19172.0
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
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: 19172.0
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.

Going ahead to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 19172.0
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.

The quotient of the division is 19172.0, and the remainder is 0.0.
