76403357 ÷ 99 
We're looking to find how many times 99 goes into 76403357.

Advancing to step 1:
The number 99 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 99

Going ahead to step 2:
76 divided by 99 is 0 with a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Take the next digit (4) from the dividend and append it to 76, then repeat: 764 / 99

Moving on to step 3:
99 goes into 764 7 times with a remainder of 71.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 693 from 764 and we're left with 71.
Append the next digit (0) from the dividend to 71 and continue with: 710 / 99

Moving on to step 4:
The number 99 fits into 710 7 times, leaving a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
Subtract 693 from 710 to get 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 99

Step 5:
The number 99 fits into 173 1 times, leaving a remainder of 74.
The next digit of our result is 1. 
Result so far: 771.0
If we take 99 away from 173, we end up with 74.
Grab the next digit (3) from the dividend, add it to 74, then carry on: 743 / 99

Advancing to step 6:
743 divided by 99 is 7 with a remainder of 50.
The next digit of our result is 7. 
Result so far: 7717.0
If we take 693 away from 743, we end up with 50.
Take the next digit (5) from the dividend and append it to 50, then repeat: 505 / 99

Going ahead to step 7:
99 can be fit into 505 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 77175.0
If we subtract 495 from 505, we get 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 99

Moving on to step 8:
When dividing 107 by 99, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 771751.0
Subtract 99 from 107 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
If we divide 80 by 99, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 771751.0
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
99 goes into 800 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 771751.08
The remainder is 8 after subtracting 792 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
The number 99 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 771751.08
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
99 can be fit into 800 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 771751.0808
Deduct 792 from 800 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
99 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 771751.0808
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 14:
When dividing 800 by 99, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 771751.080808
Subtract 792 from 800 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 15:
The number 99 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 771751.080808
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 16:
When dividing 800 by 99, we get 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 771751.08080808
Subtracting 792 from 800 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 771751.08080808 with a balance of 8e-09.
