We divide 801453 by 20
We want to figure out the number of times 801453 can be divided by 20.

Going ahead to step 1:
20 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 20

Advancing to step 2:
When dividing 80 by 20, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 80 from 80 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 20

Going ahead to step 3:
1 divided by 20 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 40.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 20

Step 4:
If we divide 14 by 20, we get 0 and a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 400.0
If we take 0 away from 14, we end up with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 20

Let's proceed to step 5:
The number 20 fits into 145 7 times, leaving a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 4007.0
Deduct 140 from 145 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 20

Let's proceed to step 6:
The number 20 fits into 53 2 times, leaving a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 40072.0
If we take 40 away from 53, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
If we divide 130 by 20, we get 6 and a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 40072.6
If we take 120 away from 130, 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.

Let's proceed to step 8:
20 goes into 100 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 40072.65
Subtract 100 from 100 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.

Let's proceed to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40072.65
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.

Let's proceed to step 10:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40072.65
The remainder is 0 after subtracting 0 from 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 40072.65, with a leftover of 0.0.
