We're dividing 720838 by 45 
We're looking to find how many times 45 goes into 720838.

Advancing to step 1:
7 divided by 45 is 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.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 45

Moving on to step 2:
If we divide 72 by 45, we get 1 and a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 45 away from 72, we end up with 27.
Fetch the next digit (0) from the dividend, attach it to 27 and continue: 270 / 45

Moving on to step 3:
270 divided by 45 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 16.0
Subtract 270 from 270 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 45

Going ahead to step 4:
8 divided by 45 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 160.0
If we subtract 0 from 8, we get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 45

Step 5:
The number 45 fits into 83 1 times, leaving a remainder of 38.
The next digit of our result is 1. 
Result so far: 1601.0
The remainder is 38 after subtracting 45 from 83.
Bring next digit (8) of the dividend behind the 38 and repeat the process: 388 / 45

On to step 6:
When dividing 388 by 45, we get 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 16018.0
If we take 360 away from 388, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
When dividing 280 by 45, we get 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 16018.6
If we take 270 away from 280, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
45 goes into 100 2 times with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 16018.62
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
100 divided by 45 is 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 16018.622
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 16018.622 with a balance of 0.001.
