Let's divide 787213 by 20
We want to figure out the number of times 787213 can be divided by 20.

Advancing to step 1:
20 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 20

Moving on to step 2:
When dividing 78 by 20, we get 3 with a remainder of 18.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 60 from 78 and we're left with 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 20

On to step 3:
187 divided by 20 is 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we subtract 180 from 187, we get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 20

Moving on to step 4:
20 goes into 72 3 times with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 393.0
If we take 60 away from 72, we end up with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 20

Going ahead to step 5:
If we divide 121 by 20, we get 6 and a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 3936.0
Subtract 120 from 121 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 20

Step 6:
20 goes into 13 0 times with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 39360.0
If we take 0 away from 13, 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.

Step 7:
If we divide 130 by 20, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 39360.6
The remainder is 10 after subtracting 120 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 20 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 39360.65
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.

Step 9:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 39360.65
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.

On to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 39360.65
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.

The final outcome is 39360.65, with a leftover of 0.0.
