We're dividing 77588517 by 100 
Let's see how many times 100 fits into 77588517.

Moving on to step 1:
When dividing 7 by 100, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 100

Going ahead to step 2:
The number 100 fits into 77 0 times, leaving a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (5) from the dividend, add it to 77, then carry on: 775 / 100

Moving on to step 3:
The number 100 fits into 775 7 times, leaving a remainder of 75.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 700 from 775 leaves us with 75.
Include the next digit (8) from the dividend after 75, then repeat: 758 / 100

Advancing to step 4:
758 divided by 100 is 7 with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 77.0
Subtracting 700 from 758 leaves us with 58.
Append the next digit (8) from the dividend to 58 and continue with: 588 / 100

On to step 5:
588 divided by 100 is 5 with a remainder of 88.
The next digit of our result is 5. 
Result so far: 775.0
Subtract 500 from 588 to get 88.
Fetch the next digit (5) from the dividend, attach it to 88 and continue: 885 / 100

Step 6:
When dividing 885 by 100, we get 8 with a remainder of 85.
The number 8 becomes the next digit in our result. 
Result so far: 7758.0
If we take 800 away from 885, we end up with 85.
Append the next digit (1) from the dividend to 85 and continue with: 851 / 100

Step 7:
When dividing 851 by 100, we get 8 with a remainder of 51.
Use 8 as the next digit of our solution. 
Result so far: 77588.0
If we subtract 800 from 851, we get 51.
Take the next digit (7) from the dividend and append it to 51, then repeat: 517 / 100

Advancing to step 8:
517 divided by 100 is 5 with a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 775885.0
Deduct 500 from 517 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
When dividing 170 by 100, we get 1 with a remainder of 70.
Put 1 as the next digit of the answer. 
Result so far: 775885.1
Deduct 100 from 170 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
When dividing 700 by 100, we get 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 775885.17
Deduct 700 from 700 and we're left 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.

Advancing to step 11:
0 divided by 100 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 775885.17
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.

Advancing to step 12:
When dividing 0 by 100, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 775885.17
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 775885.17 and a remainder of 0.0.
