Let's divide 781197 by 20
We're looking to find how many times 20 goes into 781197.

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
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 20

Going ahead to step 2:
20 goes into 78 3 times with a remainder of 18.
The next digit of our result is 3. 
Result so far: 3.0
If we take 60 away from 78, we end up with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 20

On to step 3:
20 goes into 181 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 39.0
Subtracting 180 from 181 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 20

On to step 4:
If we divide 11 by 20, we get 0 and a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 390.0
The remainder is 11 after subtracting 0 from 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 20

Going ahead to step 5:
If we divide 119 by 20, we get 5 and a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 3905.0
The remainder is 19 after subtracting 100 from 119.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 20

Advancing to step 6:
If we divide 197 by 20, we get 9 and a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 39059.0
If we take 180 away from 197, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
If we divide 170 by 20, we get 8 and a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 39059.8
If we take 160 away from 170, 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.

On to step 8:
100 divided by 20 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 39059.85
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.

Step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 39059.85
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.

Going ahead to step 10:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 39059.85
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 final outcome is 39059.85, with a leftover of 0.0.
