We're dividing 830479 by 20 
We want to figure out the number of times 830479 can be divided by 20.

Let's proceed to step 1:
20 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 20

Advancing to step 2:
The number 20 fits into 83 4 times, leaving a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 80 from 83 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 20

Advancing to step 3:
30 divided by 20 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 41.0
The remainder is 10 after subtracting 20 from 30.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 20

Advancing to step 4:
If we divide 104 by 20, we get 5 and a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 415.0
Deduct 100 from 104 and we're left with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 20

Going ahead to step 5:
When dividing 47 by 20, we get 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 4152.0
Deduct 40 from 47 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 20

On to step 6:
20 can be fit into 79 3 times, resulting in a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 41523.0
If we subtract 60 from 79, 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.

Let's proceed to step 7:
When dividing 190 by 20, we get 9 with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 41523.9
Subtracting 180 from 190 leaves us 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.

Advancing to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 41523.95
The remainder is 0 after subtracting 100 from 100.
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 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 41523.95
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.

Advancing to step 10:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 41523.95
If we take 0 away from 0, 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.

The quotient of the division is 41523.95, and the remainder is 0.0.
