831581 divided by 20 
The aim is to understand the frequency of 20 in 831581.

Advancing to step 1:
20 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 20

Moving on to step 2:
20 can be fit into 83 4 times, resulting in a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 3 after subtracting 80 from 83.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 20

Going ahead to step 3:
If we divide 31 by 20, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
If we subtract 20 from 31, we get 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 20

On to step 4:
20 can be fit into 115 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 415.0
Subtracting 100 from 115 leaves us with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 20

Advancing to step 5:
20 goes into 158 7 times with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 4157.0
Subtracting 140 from 158 leaves us with 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 20

Step 6:
When dividing 181 by 20, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 41579.0
The remainder is 1 after subtracting 180 from 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
20 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 41579.0
If we take 0 away from 10, we end up 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.

Step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 41579.05
Deduct 100 from 100 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.

Going ahead 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: 41579.05
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.

Moving on to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 41579.05
Subtract 0 from 0 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.

In conclusion, the division gives 41579.05 with a balance of 0.0.
