We're dividing 80449140 by 434 
We want to divide 80449140 by 434.

On to step 1:
434 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 434

Moving on to step 2:
80 divided by 434 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Grab the next digit (4) from the dividend, add it to 80, then carry on: 804 / 434

On to step 3:
The number 434 fits into 804 1 times, leaving a remainder of 370.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 434 from 804 to get 370.
Grab the next digit (4) from the dividend, add it to 370, then carry on: 3704 / 434

Advancing to step 4:
434 can be fit into 3704 8 times, resulting in a remainder of 232.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 3472 from 3704 and we're left with 232.
Append the next digit (9) from the dividend to 232 and continue with: 2329 / 434

Let's proceed to step 5:
When dividing 2329 by 434, we get 5 with a remainder of 159.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
If we take 2170 away from 2329, we end up with 159.
Fetch the next digit (1) from the dividend, attach it to 159 and continue: 1591 / 434

Moving on to step 6:
434 can be fit into 1591 3 times, resulting in a remainder of 289.
Use 3 as the next digit of our solution. 
Result so far: 1853.0
Deduct 1302 from 1591 and we're left with 289.
Take the next digit (4) from the dividend and append it to 289, then repeat: 2894 / 434

On to step 7:
434 can be fit into 2894 6 times, resulting in a remainder of 290.
Write down 6 as next digit of the result. 
Result so far: 18536.0
Deduct 2604 from 2894 and we're left with 290.
Include the next digit (0) from the dividend after 290, then repeat: 2900 / 434

Step 8:
434 goes into 2900 6 times with a remainder of 296.
The number 6 becomes the next digit in our result. 
Result so far: 185366.0
Subtracting 2604 from 2900 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 9:
434 goes into 2960 6 times with a remainder of 356.
Write down 6 as next digit of the result. 
Result so far: 185366.6
If we subtract 2604 from 2960, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 10:
When dividing 3560 by 434, we get 8 with a remainder of 88.
The number 8 becomes the next digit in our result. 
Result so far: 185366.68
The remainder is 88 after subtracting 3472 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 11:
If we divide 880 by 434, we get 2 and a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 185366.682
Subtract 868 from 880 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
434 goes into 120 0 times with a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 185366.682
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 13:
The number 434 fits into 1200 2 times, leaving a remainder of 332.
The number 2 becomes the next digit in our result. 
Result so far: 185366.68202
Subtract 868 from 1200 to get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 14:
3320 divided by 434 is 7 with a remainder of 282.
Write down 7 as next digit of the result. 
Result so far: 185366.682027
If we subtract 3038 from 3320, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 15:
The number 434 fits into 2820 6 times, leaving a remainder of 216.
The number 6 becomes the next digit in our result. 
Result so far: 185366.6820276
Subtract 2604 from 2820 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 16:
434 can be fit into 2160 4 times, resulting in a remainder of 424.
Use 4 as the next digit of our solution. 
Result so far: 185366.68202764
The remainder is 424 after subtracting 1736 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

The final result is 185366.68202764 with a remainder of 4.24e-07.
