36190113 divided by 20 
The aim is to understand the frequency of 20 in 36190113.

On to step 1:
If we divide 3 by 20, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 20

On to step 2:
The number 20 fits into 36 1 times, leaving a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 20 from 36 leaves us with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 20

On to step 3:
161 divided by 20 is 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we take 160 away from 161, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 20

Going ahead to step 4:
When dividing 19 by 20, we get 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 180.0
The remainder is 19 after subtracting 0 from 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 20

Let's proceed to step 5:
If we divide 190 by 20, we get 9 and a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 1809.0
Subtracting 180 from 190 leaves us with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 20

Let's proceed to step 6:
101 divided by 20 is 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 18095.0
If we take 100 away from 101, we end up with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 20

Let's proceed to step 7:
If we divide 11 by 20, we get 0 and a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 180950.0
The remainder is 11 after subtracting 0 from 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 20

On to step 8:
If we divide 113 by 20, we get 5 and a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 1809505.0
If we take 100 away from 113, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
130 divided by 20 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 1809505.6
Subtracting 120 from 130 leaves us 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.

Advancing to step 10:
20 goes into 100 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 1809505.65
If we take 100 away from 100, 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.

On to step 11:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1809505.65
If we subtract 0 from 0, we 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.

Going ahead to step 12:
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: 1809505.65
If we subtract 0 from 0, we 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.

The quotient of the division is 1809505.65, and the remainder is 0.0.
