72573248 ÷ 434 
We want to figure out the number of times 72573248 can be divided by 434.

Let's proceed to step 1:
434 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 434

Let's proceed to step 2:
When dividing 72 by 434, we get 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Append the next digit (5) from the dividend to 72 and continue with: 725 / 434

Advancing to step 3:
434 goes into 725 1 times with a remainder of 291.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 434 from 725 to get 291.
Append the next digit (7) from the dividend to 291 and continue with: 2917 / 434

On to step 4:
434 goes into 2917 6 times with a remainder of 313.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we subtract 2604 from 2917, we get 313.
Grab the next digit (3) from the dividend, add it to 313, then carry on: 3133 / 434

Advancing to step 5:
3133 divided by 434 is 7 with a remainder of 95.
Put 7 as the next digit of the answer. 
Result so far: 167.0
If we take 3038 away from 3133, we end up with 95.
Take the next digit (2) from the dividend and append it to 95, then repeat: 952 / 434

On to step 6:
If we divide 952 by 434, we get 2 and a remainder of 84.
The number 2 becomes the next digit in our result. 
Result so far: 1672.0
The remainder is 84 after subtracting 868 from 952.
Append the next digit (4) from the dividend to 84 and continue with: 844 / 434

Moving on to step 7:
The number 434 fits into 844 1 times, leaving a remainder of 410.
Use 1 as the next digit of our solution. 
Result so far: 16721.0
If we take 434 away from 844, we end up with 410.
Grab the next digit (8) from the dividend, add it to 410, then carry on: 4108 / 434

Let's proceed to step 8:
The number 434 fits into 4108 9 times, leaving a remainder of 202.
Record the quotient 9 as the next digit in the result. 
Result so far: 167219.0
Subtracting 3906 from 4108 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 9:
434 goes into 2020 4 times with a remainder of 284.
Write down 4 as next digit of the result. 
Result so far: 167219.4
The remainder is 284 after subtracting 1736 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Advancing to step 10:
The number 434 fits into 2840 6 times, leaving a remainder of 236.
The number 6 becomes the next digit in our result. 
Result so far: 167219.46
If we take 2604 away from 2840, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 11:
When dividing 2360 by 434, we get 5 with a remainder of 190.
Put 5 as the next digit of the answer. 
Result so far: 167219.465
Deduct 2170 from 2360 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 12:
434 goes into 1900 4 times with a remainder of 164.
Use 4 as the next digit of our solution. 
Result so far: 167219.4654
Deduct 1736 from 1900 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 13:
The number 434 fits into 1640 3 times, leaving a remainder of 338.
Record the quotient 3 as the next digit in the result. 
Result so far: 167219.46543
The remainder is 338 after subtracting 1302 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Step 14:
The number 434 fits into 3380 7 times, leaving a remainder of 342.
Record the quotient 7 as the next digit in the result. 
Result so far: 167219.465437
Subtract 3038 from 3380 to get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

On to step 15:
The number 434 fits into 3420 7 times, leaving a remainder of 382.
The next digit of our result is 7. 
Result so far: 167219.4654377
If we subtract 3038 from 3420, we get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

After the division, we end up with 167219.4654377 and a remainder of 3.82e-06.
