Let's divide 43154272 by 80
We're looking to find how many times 80 goes into 43154272.

Advancing to step 1:
The number 80 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 80

Let's proceed to step 2:
When dividing 43 by 80, we get 0 with 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.
Include the next digit (1) from the dividend after 43, then repeat: 431 / 80

On to step 3:
The number 80 fits into 431 5 times, leaving a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 400 from 431 to get 31.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 80

On to step 4:
80 can be fit into 315 3 times, resulting in a remainder of 75.
Write down 3 as next digit of the result. 
Result so far: 53.0
Subtract 240 from 315 to get 75.
Append the next digit (4) from the dividend to 75 and continue with: 754 / 80

Advancing to step 5:
When dividing 754 by 80, we get 9 with a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 539.0
Subtracting 720 from 754 leaves us with 34.
Grab the next digit (2) from the dividend, add it to 34, then carry on: 342 / 80

Going ahead to step 6:
342 divided by 80 is 4 with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 5394.0
Deduct 320 from 342 and we're left with 22.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 80

Advancing to step 7:
The number 80 fits into 227 2 times, leaving a remainder of 67.
Use 2 as the next digit of our solution. 
Result so far: 53942.0
The remainder is 67 after subtracting 160 from 227.
Append the next digit (2) from the dividend to 67 and continue with: 672 / 80

Advancing to step 8:
If we divide 672 by 80, we get 8 and a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 539428.0
Subtract 640 from 672 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
When dividing 320 by 80, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 539428.4
Subtract 320 from 320 to 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.

On to step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 539428.4
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.

Advancing to step 11:
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: 539428.4
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.

The final result is 539428.4 with a remainder of 0.0.
