943159 divided by 20 
The aim is to understand the frequency of 20 in 943159.

Advancing to step 1:
20 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 20

Moving on to step 2:
20 goes into 94 4 times with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 14 after subtracting 80 from 94.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 20

Going ahead to step 3:
If we divide 143 by 20, we get 7 and a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Subtract 140 from 143 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 20

Step 4:
If we divide 31 by 20, we get 1 and a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 471.0
Subtracting 20 from 31 leaves us with 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 20

Moving on to step 5:
20 can be fit into 115 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 4715.0
Deduct 100 from 115 and we're left with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 20

On to step 6:
The number 20 fits into 159 7 times, leaving a remainder of 19.
The next digit of our result is 7. 
Result so far: 47157.0
If we subtract 140 from 159, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
When dividing 190 by 20, we get 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 47157.9
Deduct 180 from 190 and we're left 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.

Let's proceed to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 47157.95
If we subtract 100 from 100, 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.

On to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 47157.95
The remainder is 0 after subtracting 0 from 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 10:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 47157.95
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.

The final outcome is 47157.95, with a leftover of 0.0.
