We're dividing 831469 by 20 
Let's see how many times 20 fits into 831469.

Step 1:
20 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 20

Step 2:
The number 20 fits into 83 4 times, leaving 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.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 20

Going ahead to step 3:
31 divided by 20 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 41.0
The remainder is 11 after subtracting 20 from 31.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 20

Let's proceed to step 4:
114 divided by 20 is 5 with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 415.0
If we subtract 100 from 114, we get 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 20

Let's proceed to step 5:
When dividing 146 by 20, we get 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 4157.0
The remainder is 6 after subtracting 140 from 146.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 20

Advancing to step 6:
When dividing 69 by 20, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 41573.0
Subtracting 60 from 69 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
90 divided by 20 is 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 41573.4
The remainder is 10 after subtracting 80 from 90.
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:
The number 20 fits into 100 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 41573.45
Subtracting 100 from 100 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.

Moving on to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 41573.45
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 10:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 41573.45
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.

The final result is 41573.45 with a remainder of 0.0.
