We divide 23790669 by 20
The aim is to understand the frequency of 20 in 23790669.

Step 1:
The number 20 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 20

Let's proceed to step 2:
23 divided by 20 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 20 from 23 to get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 20

Let's proceed to step 3:
37 divided by 20 is 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 20 from 37 leaves us with 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 20

Let's proceed to step 4:
20 goes into 179 8 times with a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 118.0
If we subtract 160 from 179, we get 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 20

Going ahead to step 5:
190 divided by 20 is 9 with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 1189.0
Deduct 180 from 190 and we're left with 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 20

Advancing to step 6:
The number 20 fits into 106 5 times, leaving a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 11895.0
Subtract 100 from 106 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 20

Advancing to step 7:
If we divide 66 by 20, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 118953.0
Subtracting 60 from 66 leaves us with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 20

Moving on to step 8:
20 goes into 69 3 times with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 1189533.0
Subtract 60 from 69 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
When dividing 90 by 20, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 1189533.4
If we subtract 80 from 90, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1189533.45
Subtract 100 from 100 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.

On to step 11:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1189533.45
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.

Going ahead to step 12:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1189533.45
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.

After the division, we end up with 1189533.45 and a remainder of 0.0.
