438648 divided by 80 
We want to figure out the number of times 438648 can be divided by 80.

Advancing to step 1:
If we divide 4 by 80, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 80

Step 2:
If we divide 43 by 80, we get 0 and a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Bring next digit (8) of the dividend behind the 43 and repeat the process: 438 / 80

Let's proceed to step 3:
438 divided by 80 is 5 with a remainder of 38.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 400 from 438 and we're left with 38.
Grab the next digit (6) from the dividend, add it to 38, then carry on: 386 / 80

Going ahead to step 4:
If we divide 386 by 80, we get 4 and a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 54.0
Subtract 320 from 386 to get 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 80

Step 5:
80 goes into 664 8 times with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 548.0
If we take 640 away from 664, we end up with 24.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 80

Step 6:
If we divide 248 by 80, we get 3 and a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 5483.0
If we subtract 240 from 248, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
80 divided by 80 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 5483.1
Subtracting 80 from 80 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5483.1
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5483.1
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 5483.1, with a leftover of 0.0.
