Let's divide 85283809 by 20
Our goal is to divide 85283809 by 20.

Advancing to step 1:
20 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 20

Going ahead to step 2:
85 divided by 20 is 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 4.0
If we take 80 away from 85, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 20

Advancing to step 3:
20 goes into 52 2 times with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtracting 40 from 52 leaves us with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 20

Advancing to step 4:
128 divided by 20 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 426.0
Deduct 120 from 128 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 20

Advancing to step 5:
20 can be fit into 83 4 times, resulting in a remainder of 3.
The next digit of our result is 4. 
Result so far: 4264.0
If we take 80 away from 83, we end up with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 20

Going ahead to step 6:
The number 20 fits into 38 1 times, leaving a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 42641.0
Deduct 20 from 38 and we're left with 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 20

Let's proceed to step 7:
20 can be fit into 180 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 426419.0
If we take 180 away from 180, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 20

Moving on to step 8:
20 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 4264190.0
If we take 0 away from 9, we end up 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.

Going ahead to step 9:
20 can be fit into 90 4 times, resulting in a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 4264190.4
Subtract 80 from 90 to get 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 10:
20 can be fit into 100 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 4264190.45
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.

On to step 11:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4264190.45
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.

Going ahead to step 12:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4264190.45
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.

The quotient of the division is 4264190.45, and the remainder is 0.0.
