We divide 19139778 by 20
The aim is to understand the frequency of 20 in 19139778.

Going ahead to step 1:
20 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 20

Moving on to step 2:
The number 20 fits into 19 0 times, leaving a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 20

Let's proceed to step 3:
191 divided by 20 is 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 180 from 191, we get 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 20

Step 4:
113 divided by 20 is 5 with a remainder of 13.
The next digit of our result is 5. 
Result so far: 95.0
If we take 100 away from 113, we end up with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 20

Let's proceed to step 5:
20 goes into 139 6 times with a remainder of 19.
The next digit of our result is 6. 
Result so far: 956.0
Deduct 120 from 139 and we're left with 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 20

Let's proceed to step 6:
197 divided by 20 is 9 with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 9569.0
If we take 180 away from 197, we end up with 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 20

Moving on to step 7:
When dividing 177 by 20, we get 8 with a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 95698.0
Deduct 160 from 177 and we're left with 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 20

On to step 8:
20 can be fit into 178 8 times, resulting in a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 956988.0
The remainder is 18 after subtracting 160 from 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
20 goes into 180 9 times with a remainder of 0.
The next digit of our result is 9. 
Result so far: 956988.9
Subtract 180 from 180 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.

Step 10:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 956988.9
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.

Moving on to step 11:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 956988.9
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.

Our division results in 956988.9 with a remaining 0.0.
