We're dividing 673438 by 72 
We want to figure out the number of times 673438 can be divided by 72.

On to step 1:
72 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 72

Advancing to step 2:
When dividing 67 by 72, we get 0 with a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Take the next digit (3) from the dividend and append it to 67, then repeat: 673 / 72

Moving on to step 3:
When dividing 673 by 72, we get 9 with a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 25 after subtracting 648 from 673.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 72

Going ahead to step 4:
The number 72 fits into 254 3 times, leaving a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 93.0
If we take 216 away from 254, we end up with 38.
Bring next digit (3) of the dividend behind the 38 and repeat the process: 383 / 72

Going ahead to step 5:
If we divide 383 by 72, we get 5 and a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 935.0
If we subtract 360 from 383, we get 23.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 72

Going ahead to step 6:
72 goes into 238 3 times with a remainder of 22.
The next digit of our result is 3. 
Result so far: 9353.0
If we subtract 216 from 238, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
The number 72 fits into 220 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 9353.3
If we subtract 216 from 220, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
40 divided by 72 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 9353.3
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
72 goes into 400 5 times with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 9353.305
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
If we divide 400 by 72, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 9353.3055
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 9353.3055 with a balance of 0.0004.
