772145 divided by 20 
We want to divide 772145 by 20.

Let's proceed to step 1:
If we divide 7 by 20, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 20

On to step 2:
If we divide 77 by 20, we get 3 and a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 60 away from 77, we end up with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 20

Going ahead to step 3:
The number 20 fits into 172 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
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:
20 goes into 121 6 times with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 386.0
The remainder is 1 after subtracting 120 from 121.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 20

Going ahead to step 5:
If we divide 14 by 20, we get 0 and a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 3860.0
If we take 0 away from 14, we end up with 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 20

On to step 6:
When dividing 145 by 20, we get 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 38607.0
Subtracting 140 from 145 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
50 divided by 20 is 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 38607.2
If we subtract 40 from 50, we 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.

Step 8:
20 goes into 100 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 38607.25
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.

Going ahead to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 38607.25
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: 38607.25
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.

The quotient of the division is 38607.25, and the remainder is 0.0.
