We look at the division of 874762 by 20 
The aim is to understand the frequency of 20 in 874762.

Step 1:
20 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 20

Let's proceed to step 2:
87 divided by 20 is 4 with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 80 from 87 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 20

Let's proceed to step 3:
20 goes into 74 3 times with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
If we take 60 away from 74, we end up with 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 20

Advancing to step 4:
The number 20 fits into 147 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 437.0
If we take 140 away from 147, we end up with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 20

Advancing to step 5:
20 goes into 76 3 times with a remainder of 16.
The next digit of our result is 3. 
Result so far: 4373.0
If we take 60 away from 76, we end up with 16.
Take the next digit (2) from the dividend and append it to 16, then repeat: 162 / 20

Moving on to step 6:
If we divide 162 by 20, we get 8 and a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 43738.0
The remainder is 2 after subtracting 160 from 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
When dividing 20 by 20, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 43738.1
Deduct 20 from 20 and we're left 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 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 43738.1
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.

Moving on to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43738.1
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.

The final result is 43738.1 with a remainder of 0.0.
