783444 divided by 45 
We want to divide 783444 by 45.

On to step 1:
When dividing 7 by 45, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 45

Step 2:
78 divided by 45 is 1 with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 45 from 78 leaves us with 33.
Bring next digit (3) of the dividend behind the 33 and repeat the process: 333 / 45

Going ahead to step 3:
When dividing 333 by 45, we get 7 with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 315 from 333 leaves us with 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 45

Going ahead to step 4:
184 divided by 45 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 174.0
If we take 180 away from 184, we end up with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 45

Going ahead to step 5:
When dividing 44 by 45, we get 0 with a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 1740.0
Subtract 0 from 44 to get 44.
Grab the next digit (4) from the dividend, add it to 44, then carry on: 444 / 45

On to step 6:
45 can be fit into 444 9 times, resulting in a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 17409.0
The remainder is 39 after subtracting 405 from 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
45 goes into 390 8 times with a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 17409.8
Subtract 360 from 390 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
45 goes into 300 6 times with a remainder of 30.
The next digit of our result is 6. 
Result so far: 17409.86
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
300 divided by 45 is 6 with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 17409.866
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 17409.866, with a leftover of 0.003.
