753823 ÷ 20 
We're looking to find how many times 20 goes into 753823.

Going ahead to step 1:
When dividing 7 by 20, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 20

Going ahead to step 2:
When dividing 75 by 20, we get 3 with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 15 after subtracting 60 from 75.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 20

Moving on to step 3:
If we divide 153 by 20, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we take 140 away from 153, we end up with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 20

Going ahead to step 4:
20 can be fit into 138 6 times, resulting in a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 376.0
Subtracting 120 from 138 leaves us with 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 20

Moving on to step 5:
20 goes into 182 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 3769.0
If we take 180 away from 182, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 20

On to step 6:
20 goes into 23 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 37691.0
If we take 20 away from 23, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
20 can be fit into 30 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 37691.1
If we subtract 20 from 30, we 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.

Going ahead to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 37691.15
If we take 100 away from 100, 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.

Step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 37691.15
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.

Advancing to step 10:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 37691.15
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 final outcome is 37691.15, with a leftover of 0.0.
