912435 divided by 80 
We're looking to find how many times 80 goes into 912435.

On to step 1:
When dividing 9 by 80, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 80

Let's proceed to step 2:
When dividing 91 by 80, we get 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 80 from 91 leaves us with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 80

Moving on to step 3:
80 goes into 112 1 times with a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 80 from 112 leaves us with 32.
Grab the next digit (4) from the dividend, add it to 32, then carry on: 324 / 80

Moving on to step 4:
80 can be fit into 324 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 114.0
If we subtract 320 from 324, we get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 80

On to step 5:
80 goes into 43 0 times with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 1140.0
Subtract 0 from 43 to get 43.
Append the next digit (5) from the dividend to 43 and continue with: 435 / 80

Step 6:
80 goes into 435 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 11405.0
Subtracting 400 from 435 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
When dividing 350 by 80, we get 4 with a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 11405.4
Subtract 320 from 350 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
The number 80 fits into 300 3 times, leaving a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 11405.43
If we subtract 240 from 300, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
80 goes into 600 7 times with a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 11405.437
If we take 560 away from 600, we end up 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.

Going ahead to step 10:
80 goes into 400 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 11405.4375
If we take 400 away from 400, 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.

Let's proceed to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 11405.4375
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.

Going ahead to step 12:
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: 11405.4375
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.

In conclusion, the division gives 11405.4375 with a balance of 0.0.
