432438 divided by 80 
We want to figure out the number of times 432438 can be divided by 80.

On to step 1:
The number 80 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 80

Step 2:
80 can be fit into 43 0 times, resulting in a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Grab the next digit (2) from the dividend, add it to 43, then carry on: 432 / 80

Going ahead to step 3:
The number 80 fits into 432 5 times, leaving a remainder of 32.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 400 from 432 leaves us with 32.
Fetch the next digit (4) from the dividend, attach it to 32 and continue: 324 / 80

Advancing to step 4:
When dividing 324 by 80, we get 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 54.0
Subtracting 320 from 324 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 80

Advancing to step 5:
80 goes into 43 0 times with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 540.0
The remainder is 43 after subtracting 0 from 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 80

Moving on to step 6:
When dividing 438 by 80, we get 5 with a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 5405.0
If we take 400 away from 438, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
When dividing 380 by 80, we get 4 with a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 5405.4
Subtracting 320 from 380 leaves us 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.

Advancing to step 8:
600 divided by 80 is 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 5405.47
The remainder is 40 after subtracting 560 from 600.
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 9:
80 can be fit into 400 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5405.475
Subtracting 400 from 400 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.

Advancing to step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5405.475
If we subtract 0 from 0, we get 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 11:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5405.475
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 result is 5405.475 with a remainder of 0.0.
