We're dividing 72989116 by 434 
We want to figure out the number of times 72989116 can be divided by 434.

On to step 1:
When dividing 7 by 434, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 434

Advancing to step 2:
If we divide 72 by 434, we get 0 and a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Bring next digit (9) of the dividend behind the 72 and repeat the process: 729 / 434

Let's proceed to step 3:
If we divide 729 by 434, we get 1 and a remainder of 295.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 295 after subtracting 434 from 729.
Include the next digit (8) from the dividend after 295, then repeat: 2958 / 434

Going ahead to step 4:
When dividing 2958 by 434, we get 6 with a remainder of 354.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 2604 from 2958 and we're left with 354.
Append the next digit (9) from the dividend to 354 and continue with: 3549 / 434

Going ahead to step 5:
If we divide 3549 by 434, we get 8 and a remainder of 77.
Put 8 as the next digit of the answer. 
Result so far: 168.0
If we subtract 3472 from 3549, we get 77.
Append the next digit (1) from the dividend to 77 and continue with: 771 / 434

Going ahead to step 6:
The number 434 fits into 771 1 times, leaving a remainder of 337.
The number 1 becomes the next digit in our result. 
Result so far: 1681.0
If we take 434 away from 771, we end up with 337.
Append the next digit (1) from the dividend to 337 and continue with: 3371 / 434

Let's proceed to step 7:
When dividing 3371 by 434, we get 7 with a remainder of 333.
The number 7 becomes the next digit in our result. 
Result so far: 16817.0
Subtract 3038 from 3371 to get 333.
Grab the next digit (6) from the dividend, add it to 333, then carry on: 3336 / 434

Step 8:
3336 divided by 434 is 7 with a remainder of 298.
Record the quotient 7 as the next digit in the result. 
Result so far: 168177.0
Subtracting 3038 from 3336 leaves us with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Advancing to step 9:
The number 434 fits into 2980 6 times, leaving a remainder of 376.
The number 6 becomes the next digit in our result. 
Result so far: 168177.6
Deduct 2604 from 2980 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 10:
434 goes into 3760 8 times with a remainder of 288.
The next digit of our result is 8. 
Result so far: 168177.68
Subtracting 3472 from 3760 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 11:
434 can be fit into 2880 6 times, resulting in a remainder of 276.
Write down 6 as next digit of the result. 
Result so far: 168177.686
The remainder is 276 after subtracting 2604 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 12:
2760 divided by 434 is 6 with a remainder of 156.
Put 6 as the next digit of the answer. 
Result so far: 168177.6866
Deduct 2604 from 2760 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

After the division, we end up with 168177.6866 and a remainder of 0.00156.
