777521 ÷ 99 
We want to divide 777521 by 99.

Let's proceed to step 1:
When dividing 7 by 99, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 99

Moving on to step 2:
77 divided by 99 is 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Bring next digit (7) of the dividend behind the 77 and repeat the process: 777 / 99

On to step 3:
99 can be fit into 777 7 times, resulting in a remainder of 84.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 693 away from 777, we end up with 84.
Take the next digit (5) from the dividend and append it to 84, then repeat: 845 / 99

Going ahead to step 4:
99 can be fit into 845 8 times, resulting in a remainder of 53.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtracting 792 from 845 leaves us with 53.
Append the next digit (2) from the dividend to 53 and continue with: 532 / 99

Let's proceed to step 5:
If we divide 532 by 99, we get 5 and a remainder of 37.
Write down 5 as next digit of the result. 
Result so far: 785.0
If we subtract 495 from 532, we get 37.
Append the next digit (1) from the dividend to 37 and continue with: 371 / 99

Going ahead to step 6:
99 goes into 371 3 times with a remainder of 74.
Use 3 as the next digit of our solution. 
Result so far: 7853.0
If we subtract 297 from 371, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 7:
If we divide 740 by 99, we get 7 and a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 7853.7
Subtracting 693 from 740 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 8:
If we divide 470 by 99, we get 4 and a remainder of 74.
The next digit of our result is 4. 
Result so far: 7853.74
If we take 396 away from 470, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 9:
If we divide 740 by 99, we get 7 and a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 7853.747
Deduct 693 from 740 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 10:
If we divide 470 by 99, we get 4 and a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 7853.7474
Subtract 396 from 470 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 11:
If we divide 740 by 99, we get 7 and a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 7853.74747
Deduct 693 from 740 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 12:
If we divide 470 by 99, we get 4 and a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 7853.747474
If we take 396 away from 470, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 13:
740 divided by 99 is 7 with a remainder of 47.
The next digit of our result is 7. 
Result so far: 7853.7474747
Subtract 693 from 740 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 14:
470 divided by 99 is 4 with a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 7853.74747474
Subtracting 396 from 470 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

After the division, we end up with 7853.74747474 and a remainder of 7.4e-08.
