72957905 ÷ 553 
We want to figure out the number of times 72957905 can be divided by 553.

On to step 1:
When dividing 7 by 553, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 553

Going ahead to step 2:
553 goes into 72 0 times with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Bring next digit (9) of the dividend behind the 72 and repeat the process: 729 / 553

Moving on to step 3:
If we divide 729 by 553, we get 1 and a remainder of 176.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 553 from 729 and we're left with 176.
Include the next digit (5) from the dividend after 176, then repeat: 1765 / 553

Going ahead to step 4:
If we divide 1765 by 553, we get 3 and a remainder of 106.
The next digit of our result is 3. 
Result so far: 13.0
If we take 1659 away from 1765, we end up with 106.
Fetch the next digit (7) from the dividend, attach it to 106 and continue: 1067 / 553

Going ahead to step 5:
The number 553 fits into 1067 1 times, leaving a remainder of 514.
Use 1 as the next digit of our solution. 
Result so far: 131.0
If we take 553 away from 1067, we end up with 514.
Include the next digit (9) from the dividend after 514, then repeat: 5149 / 553

Going ahead to step 6:
If we divide 5149 by 553, we get 9 and a remainder of 172.
Put 9 as the next digit of the answer. 
Result so far: 1319.0
The remainder is 172 after subtracting 4977 from 5149.
Include the next digit (0) from the dividend after 172, then repeat: 1720 / 553

Advancing to step 7:
When dividing 1720 by 553, we get 3 with a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 13193.0
Subtracting 1659 from 1720 leaves us with 61.
Include the next digit (5) from the dividend after 61, then repeat: 615 / 553

On to step 8:
615 divided by 553 is 1 with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 131931.0
Subtract 553 from 615 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 9:
553 can be fit into 620 1 times, resulting in a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 131931.1
If we subtract 553 from 620, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 10:
If we divide 670 by 553, we get 1 and a remainder of 117.
The number 1 becomes the next digit in our result. 
Result so far: 131931.11
Deduct 553 from 670 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

The final result is 131931.11 with a remainder of 0.117.
