Let's divide 78816122 by 20
Our goal is to divide 78816122 by 20.

Going ahead to step 1:
20 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 20

Advancing to step 2:
When dividing 78 by 20, we get 3 with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 60 from 78 and we're left with 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 20

Advancing to step 3:
When dividing 188 by 20, we get 9 with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtracting 180 from 188 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 20

Let's proceed to step 4:
81 divided by 20 is 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 394.0
The remainder is 1 after subtracting 80 from 81.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 20

On to step 5:
16 divided by 20 is 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 3940.0
Subtracting 0 from 16 leaves us with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 20

Moving on to step 6:
When dividing 161 by 20, we get 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 39408.0
Deduct 160 from 161 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 20

Let's proceed to step 7:
20 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 394080.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 20

Step 8:
If we divide 122 by 20, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 3940806.0
If we take 120 away from 122, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
When dividing 20 by 20, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 3940806.1
Deduct 20 from 20 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.

Advancing to step 10:
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: 3940806.1
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.

Step 11:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3940806.1
The remainder is 0 after subtracting 0 from 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 3940806.1 and a remainder of 0.0.
