We divide 772116 by 20
We want to figure out the number of times 772116 can be divided by 20.

Moving on to step 1:
20 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 20

Step 2:
20 can be fit into 77 3 times, resulting in a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 60 from 77 to get 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 20

Step 3:
If we divide 172 by 20, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 38.0
Subtracting 160 from 172 leaves us with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 20

Moving on to step 4:
The number 20 fits into 121 6 times, leaving a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 386.0
Subtract 120 from 121 to get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 20

Going ahead to step 5:
20 can be fit into 11 0 times, resulting in a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 3860.0
If we take 0 away from 11, we end up with 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 20

Step 6:
116 divided by 20 is 5 with a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 38605.0
Subtract 100 from 116 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
20 goes into 160 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 38605.8
If we subtract 160 from 160, 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.

On to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 38605.8
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.

Let's proceed to step 9:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 38605.8
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.

After the division, we end up with 38605.8 and a remainder of 0.0.
