We're dividing 780455 by 61 
We're looking to find how many times 61 goes into 780455.

Advancing to step 1:
61 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 61

Step 2:
61 can be fit into 78 1 times, resulting in a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 61 from 78, we get 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 61

Step 3:
170 divided by 61 is 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 48 after subtracting 122 from 170.
Grab the next digit (4) from the dividend, add it to 48, then carry on: 484 / 61

On to step 4:
484 divided by 61 is 7 with a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
Subtracting 427 from 484 leaves us with 57.
Bring next digit (5) of the dividend behind the 57 and repeat the process: 575 / 61

Let's proceed to step 5:
575 divided by 61 is 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 1279.0
If we subtract 549 from 575, we get 26.
Take the next digit (5) from the dividend and append it to 26, then repeat: 265 / 61

On to step 6:
61 goes into 265 4 times with a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 12794.0
The remainder is 21 after subtracting 244 from 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
61 goes into 210 3 times with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 12794.3
Subtracting 183 from 210 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 8:
When dividing 270 by 61, we get 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 12794.34
The remainder is 26 after subtracting 244 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
If we divide 260 by 61, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 12794.344
Deduct 244 from 260 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 12794.344 with a remaining 0.0016.
