Let's divide 777309 by 45
We want to divide 777309 by 45.

Moving on to step 1:
45 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 45

Step 2:
The number 45 fits into 77 1 times, leaving a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 45 from 77 to get 32.
Append the next digit (7) from the dividend to 32 and continue with: 327 / 45

Advancing to step 3:
327 divided by 45 is 7 with a remainder of 12.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 315 from 327 and we're left with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 45

On to step 4:
The number 45 fits into 123 2 times, leaving a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 172.0
If we subtract 90 from 123, we get 33.
Take the next digit (0) from the dividend and append it to 33, then repeat: 330 / 45

Going ahead to step 5:
When dividing 330 by 45, we get 7 with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 1727.0
The remainder is 15 after subtracting 315 from 330.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 45

Step 6:
If we divide 159 by 45, we get 3 and a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 17273.0
The remainder is 24 after subtracting 135 from 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
The number 45 fits into 240 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 17273.5
The remainder is 15 after subtracting 225 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
The number 45 fits into 150 3 times, leaving a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 17273.53
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
When dividing 150 by 45, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 17273.533
If we subtract 135 from 150, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 17273.533 with a remaining 0.0015.
