Let's divide 801948 by 20
We're looking to find how many times 20 goes into 801948.

Step 1:
20 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 20

Moving on to step 2:
80 divided by 20 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 80 from 80 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 20

Advancing to step 3:
The number 20 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 40.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 20

Moving on to step 4:
19 divided by 20 is 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 400.0
The remainder is 19 after subtracting 0 from 19.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 20

Let's proceed to step 5:
If we divide 194 by 20, we get 9 and a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 4009.0
Subtract 180 from 194 to get 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 20

On to step 6:
20 goes into 148 7 times with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 40097.0
If we take 140 away from 148, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
When dividing 80 by 20, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 40097.4
The remainder is 0 after subtracting 80 from 80.
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 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 40097.4
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.

On to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 40097.4
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.

The final outcome is 40097.4, with a leftover of 0.0.
