374924 divided by 20 
The aim is to understand the frequency of 20 in 374924.

Advancing to step 1:
20 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 20

Let's proceed to step 2:
The number 20 fits into 37 1 times, leaving a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 20 from 37 and we're left with 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 20

Going ahead to step 3:
20 goes into 174 8 times with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 160 from 174 and we're left with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 20

On to step 4:
20 can be fit into 149 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 187.0
Deduct 140 from 149 and we're left with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 20

Moving on to step 5:
When dividing 92 by 20, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 1874.0
If we take 80 away from 92, we end up with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 20

On to step 6:
The number 20 fits into 124 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 18746.0
Subtract 120 from 124 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
20 goes into 40 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 18746.2
If we take 40 away from 40, 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.

Step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18746.2
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.

On to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18746.2
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.

Our division results in 18746.2 with a remaining 0.0.
