We look at the division of 703136 by 20 
The aim is to understand the frequency of 20 in 703136.

Step 1:
20 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 20

Advancing to step 2:
When dividing 70 by 20, we get 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 60 from 70 to get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 20

Advancing to step 3:
The number 20 fits into 103 5 times, leaving a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Deduct 100 from 103 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 20

Going ahead to step 4:
20 goes into 31 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 351.0
Subtract 20 from 31 to get 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 20

Going ahead to step 5:
20 can be fit into 113 5 times, resulting in a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 3515.0
Deduct 100 from 113 and we're left with 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 20

On to step 6:
When dividing 136 by 20, we get 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 35156.0
If we subtract 120 from 136, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
If we divide 160 by 20, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 35156.8
If we take 160 away from 160, 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 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 35156.8
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.

Let's proceed to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 35156.8
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 35156.8 and a remainder of 0.0.
