657399 ÷ 99 
We're looking to find how many times 99 goes into 657399.

Going ahead to step 1:
6 divided by 99 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 99

Moving on to step 2:
If we divide 65 by 99, we get 0 and a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 65 after subtracting 0 from 65.
Append the next digit (7) from the dividend to 65 and continue with: 657 / 99

Advancing to step 3:
The number 99 fits into 657 6 times, leaving a remainder of 63.
The next digit of our result is 6. 
Result so far: 6.0
If we take 594 away from 657, we end up with 63.
Grab the next digit (3) from the dividend, add it to 63, then carry on: 633 / 99

Step 4:
99 goes into 633 6 times with a remainder of 39.
Write down 6 as next digit of the result. 
Result so far: 66.0
If we subtract 594 from 633, we get 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 99

Going ahead to step 5:
99 can be fit into 399 4 times, resulting in a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 664.0
Deduct 396 from 399 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 99

Going ahead to step 6:
99 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 6640.0
The remainder is 39 after subtracting 0 from 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 7:
390 divided by 99 is 3 with a remainder of 93.
The next digit of our result is 3. 
Result so far: 6640.3
Deduct 297 from 390 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 8:
When dividing 930 by 99, we get 9 with a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 6640.39
If we take 891 away from 930, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 9:
When dividing 390 by 99, we get 3 with a remainder of 93.
The next digit of our result is 3. 
Result so far: 6640.393
Subtract 297 from 390 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 10:
When dividing 930 by 99, we get 9 with a remainder of 39.
The next digit of our result is 9. 
Result so far: 6640.3939
If we subtract 891 from 930, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 11:
When dividing 390 by 99, we get 3 with a remainder of 93.
Use 3 as the next digit of our solution. 
Result so far: 6640.39393
Subtract 297 from 390 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Going ahead to step 12:
If we divide 930 by 99, we get 9 and a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 6640.393939
Subtract 891 from 930 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 13:
99 goes into 390 3 times with a remainder of 93.
The next digit of our result is 3. 
Result so far: 6640.3939393
Subtracting 297 from 390 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 14:
99 goes into 930 9 times with a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 6640.39393939
Subtracting 891 from 930 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 6640.39393939, and the remainder is 3.9e-08.
