We're dividing 784341 by 20 
We want to divide 784341 by 20.

Moving on to step 1:
20 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 20

Going ahead to step 2:
If we divide 78 by 20, we get 3 and a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 60 from 78 leaves us with 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 20

On to step 3:
When dividing 184 by 20, we get 9 with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Deduct 180 from 184 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 20

Step 4:
If we divide 43 by 20, we get 2 and a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 392.0
The remainder is 3 after subtracting 40 from 43.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 20

Moving on to step 5:
When dividing 34 by 20, we get 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 3921.0
If we take 20 away from 34, we end up with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 20

On to step 6:
20 goes into 141 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 39217.0
If we subtract 140 from 141, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
20 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 39217.0
The remainder is 10 after subtracting 0 from 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.
Use 5 as the next digit of our solution. 
Result so far: 39217.05
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.
The next digit of our result is 0. 
Result so far: 39217.05
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.

Going ahead to step 10:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 39217.05
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 quotient of the division is 39217.05, and the remainder is 0.0.
