Let's divide 438429 by 80
Our goal is to divide 438429 by 80.

Step 1:
80 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 80

Moving on to step 2:
80 goes into 43 0 times with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 80

Let's proceed to step 3:
When dividing 438 by 80, we get 5 with a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 400 from 438 and we're left with 38.
Include the next digit (4) from the dividend after 38, then repeat: 384 / 80

On to step 4:
80 can be fit into 384 4 times, resulting in a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 54.0
Subtract 320 from 384 to get 64.
Grab the next digit (2) from the dividend, add it to 64, then carry on: 642 / 80

Moving on to step 5:
When dividing 642 by 80, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 548.0
If we subtract 640 from 642, we get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 80

Going ahead to step 6:
When dividing 29 by 80, we get 0 with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 5480.0
If we take 0 away from 29, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
If we divide 290 by 80, we get 3 and a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 5480.3
The remainder is 50 after subtracting 240 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
80 can be fit into 500 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 5480.36
Deduct 480 from 500 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
80 can be fit into 200 2 times, resulting in a remainder of 40.
The next digit of our result is 2. 
Result so far: 5480.362
If we subtract 160 from 200, 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.

Going ahead to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5480.3625
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5480.3625
Deduct 0 from 0 and we're left 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.

Going ahead to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5480.3625
If we take 0 away from 0, we end up 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 5480.3625, with a leftover of 0.0.
