438302 divided by 80 
We want to divide 438302 by 80.

Moving on to step 1:
The number 80 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 80

Moving on to step 2:
When dividing 43 by 80, we get 0 with a remainder of 43.
Record the quotient 0 as the next digit in the 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

Step 3:
80 goes into 438 5 times with a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 400 from 438 and we're left with 38.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 80

Moving on to step 4:
The number 80 fits into 383 4 times, leaving a remainder of 63.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Subtract 320 from 383 to get 63.
Grab the next digit (0) from the dividend, add it to 63, then carry on: 630 / 80

Going ahead to step 5:
When dividing 630 by 80, we get 7 with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 547.0
Subtracting 560 from 630 leaves us with 70.
Bring next digit (2) of the dividend behind the 70 and repeat the process: 702 / 80

On to step 6:
If we divide 702 by 80, we get 8 and a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 5478.0
Subtracting 640 from 702 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 7:
When dividing 620 by 80, we get 7 with a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 5478.7
If we take 560 away from 620, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
600 divided by 80 is 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 5478.77
Subtract 560 from 600 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.

The final outcome is 5478.77, with a leftover of 0.04.
