We're dividing 756390 by 99 
We're looking to find how many times 99 goes into 756390.

Step 1:
7 divided by 99 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 99

Let's proceed to step 2:
75 divided by 99 is 0 with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Append the next digit (6) from the dividend to 75 and continue with: 756 / 99

On to step 3:
756 divided by 99 is 7 with a remainder of 63.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 693 from 756, we get 63.
Grab the next digit (3) from the dividend, add it to 63, then carry on: 633 / 99

Going ahead to step 4:
If we divide 633 by 99, we get 6 and a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Deduct 594 from 633 and we're left with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 99

Let's proceed to step 5:
99 can be fit into 399 4 times, resulting in a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 764.0
If we take 396 away from 399, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 99

Going ahead to step 6:
If we divide 30 by 99, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 7640.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
When dividing 300 by 99, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 7640.3
The remainder is 3 after subtracting 297 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 8:
The number 99 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 7640.3
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
99 can be fit into 300 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 7640.303
Subtract 297 from 300 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
If we divide 30 by 99, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 7640.303
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
If we divide 300 by 99, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 7640.30303
Deduct 297 from 300 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 12:
When dividing 30 by 99, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 7640.30303
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
99 can be fit into 300 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 7640.3030303
If we take 297 away from 300, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 14:
99 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 7640.3030303
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 7640.3030303 with a remainder of 3e-08.
