We divide 7117995 by 20
The aim is to understand the frequency of 20 in 7117995.

Let's proceed to step 1:
If we divide 7 by 20, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 20

Let's proceed to step 2:
20 can be fit into 71 3 times, resulting in a remainder of 11.
The next digit of our result is 3. 
Result so far: 3.0
If we take 60 away from 71, we end up with 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 20

Let's proceed to step 3:
If we divide 111 by 20, we get 5 and a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Subtracting 100 from 111 leaves us with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 20

Let's proceed to step 4:
If we divide 117 by 20, we get 5 and a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 355.0
Subtract 100 from 117 to get 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 20

Step 5:
20 goes into 179 8 times with a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 3558.0
Deduct 160 from 179 and we're left with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 20

On to step 6:
The number 20 fits into 199 9 times, leaving a remainder of 19.
The next digit of our result is 9. 
Result so far: 35589.0
The remainder is 19 after subtracting 180 from 199.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 20

Let's proceed to step 7:
If we divide 195 by 20, we get 9 and a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 355899.0
Subtracting 180 from 195 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
150 divided by 20 is 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 355899.7
Deduct 140 from 150 and we're left 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.

On to step 9:
20 can be fit into 100 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 355899.75
The remainder is 0 after subtracting 100 from 100.
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 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 355899.75
Subtract 0 from 0 to 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 11:
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: 355899.75
Deduct 0 from 0 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.

After the division, we end up with 355899.75 and a remainder of 0.0.
