78372579 ÷ 100 
We want to figure out the number of times 78372579 can be divided by 100.

Advancing to step 1:
When dividing 7 by 100, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 100

Advancing to step 2:
The number 100 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Take the next digit (3) from the dividend and append it to 78, then repeat: 783 / 100

On to step 3:
100 goes into 783 7 times with a remainder of 83.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 83 after subtracting 700 from 783.
Include the next digit (7) from the dividend after 83, then repeat: 837 / 100

Step 4:
837 divided by 100 is 8 with a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Subtracting 800 from 837 leaves us with 37.
Append the next digit (2) from the dividend to 37 and continue with: 372 / 100

Moving on to step 5:
When dividing 372 by 100, we get 3 with a remainder of 72.
Use 3 as the next digit of our solution. 
Result so far: 783.0
Deduct 300 from 372 and we're left with 72.
Grab the next digit (5) from the dividend, add it to 72, then carry on: 725 / 100

Moving on to step 6:
100 goes into 725 7 times with a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 7837.0
Subtract 700 from 725 to get 25.
Include the next digit (7) from the dividend after 25, then repeat: 257 / 100

Step 7:
The number 100 fits into 257 2 times, leaving a remainder of 57.
Write down 2 as next digit of the result. 
Result so far: 78372.0
Subtracting 200 from 257 leaves us with 57.
Append the next digit (9) from the dividend to 57 and continue with: 579 / 100

Step 8:
100 goes into 579 5 times with a remainder of 79.
Put 5 as the next digit of the answer. 
Result so far: 783725.0
Subtracting 500 from 579 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 9:
100 goes into 790 7 times with a remainder of 90.
Put 7 as the next digit of the answer. 
Result so far: 783725.7
If we subtract 700 from 790, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
100 goes into 900 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 783725.79
The remainder is 0 after subtracting 900 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
The number 100 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 783725.79
Subtracting 0 from 0 leaves us 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.

On to step 12:
If we divide 0 by 100, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 783725.79
Subtracting 0 from 0 leaves us 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.

The quotient of the division is 783725.79, and the remainder is 0.0.
