778820 divided by 45 
Our goal is to divide 778820 by 45.

On to step 1:
The number 45 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 45

Moving on to step 2:
45 can be fit into 77 1 times, resulting in a remainder of 32.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 45 from 77 leaves us with 32.
Append the next digit (8) from the dividend to 32 and continue with: 328 / 45

Step 3:
If we divide 328 by 45, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 315 from 328 and we're left with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 45

Let's proceed to step 4:
If we divide 138 by 45, we get 3 and a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 173.0
Subtracting 135 from 138 leaves us with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 45

Going ahead to step 5:
When dividing 32 by 45, we get 0 with a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 1730.0
The remainder is 32 after subtracting 0 from 32.
Take the next digit (0) from the dividend and append it to 32, then repeat: 320 / 45

Advancing to step 6:
45 can be fit into 320 7 times, resulting in a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 17307.0
If we subtract 315 from 320, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
50 divided by 45 is 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 17307.1
Subtracting 45 from 50 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 8:
If we divide 50 by 45, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 17307.11
Deduct 45 from 50 and we're left 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.

Our division results in 17307.11 with a remaining 0.005.
