Let's divide 78416730 by 20
We're looking to find how many times 20 goes into 78416730.

Advancing to step 1:
When dividing 7 by 20, we get 0 with a remainder of 7.
The next digit of our result is 0. 
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

Advancing to step 2:
If we divide 78 by 20, we get 3 and 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.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 20

Advancing to step 3:
20 can be fit into 184 9 times, resulting in a remainder of 4.
The next digit of our result is 9. 
Result so far: 39.0
If we subtract 180 from 184, we get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 20

Step 4:
20 goes into 41 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 392.0
Subtracting 40 from 41 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 20

Going ahead to step 5:
16 divided by 20 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 3920.0
If we take 0 away from 16, we end up with 16.
Grab the next digit (7) from the dividend, add it to 16, then carry on: 167 / 20

Moving on to step 6:
When dividing 167 by 20, we get 8 with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 39208.0
If we subtract 160 from 167, we get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 20

Moving on to step 7:
If we divide 73 by 20, we get 3 and a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 392083.0
Subtracting 60 from 73 leaves us with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 20

On to step 8:
The number 20 fits into 130 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 3920836.0
Subtract 120 from 130 to get 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 9:
20 goes into 100 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 3920836.5
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.

Advancing to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3920836.5
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.

On to step 11:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 3920836.5
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.

After the division, we end up with 3920836.5 and a remainder of 0.0.
