We divide 377831 by 20
The aim is to understand the frequency of 20 in 377831.

Moving on to step 1:
20 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 20

Let's proceed to step 2:
If we divide 37 by 20, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 20 from 37 to get 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 20

Step 3:
The number 20 fits into 177 8 times, leaving a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 18.0
The remainder is 17 after subtracting 160 from 177.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 20

Advancing to step 4:
The number 20 fits into 178 8 times, leaving a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 188.0
Deduct 160 from 178 and we're left with 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 20

On to step 5:
When dividing 183 by 20, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 1889.0
If we take 180 away from 183, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 20

Moving on to step 6:
20 goes into 31 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 18891.0
Subtracting 20 from 31 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
When dividing 110 by 20, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 18891.5
If we take 100 away from 110, we end up 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.

Advancing to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 18891.55
If we take 100 away from 100, 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.

After the division, we end up with 18891.55 and a remainder of 0.0.
