We look at the division of 74671428 by 20 
The aim is to understand the frequency of 20 in 74671428.

Let's proceed to step 1:
7 divided by 20 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 20

On to step 2:
When dividing 74 by 20, we get 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 60 from 74 and we're left with 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 20

Advancing to step 3:
20 can be fit into 146 7 times, resulting in a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
If we subtract 140 from 146, we get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 20

Step 4:
If we divide 67 by 20, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 373.0
Subtract 60 from 67 to get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 20

Going ahead to step 5:
71 divided by 20 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 3733.0
Deduct 60 from 71 and we're left with 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 20

Let's proceed to step 6:
20 can be fit into 114 5 times, resulting in a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 37335.0
Deduct 100 from 114 and we're left with 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 20

Step 7:
142 divided by 20 is 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 373357.0
Deduct 140 from 142 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 20

On to step 8:
20 goes into 28 1 times with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 3733571.0
Subtracting 20 from 28 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
80 divided by 20 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 3733571.4
Deduct 80 from 80 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.

Advancing to step 10:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3733571.4
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.

Advancing to step 11:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3733571.4
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.

In conclusion, the division gives 3733571.4 with a balance of 0.0.
