674388 divided by 99 
We're looking to find how many times 99 goes into 674388.

Going ahead to step 1:
When dividing 6 by 99, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 99

Step 2:
99 can be fit into 67 0 times, resulting in a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Take the next digit (4) from the dividend and append it to 67, then repeat: 674 / 99

Step 3:
The number 99 fits into 674 6 times, leaving a remainder of 80.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 80 after subtracting 594 from 674.
Bring next digit (3) of the dividend behind the 80 and repeat the process: 803 / 99

On to step 4:
The number 99 fits into 803 8 times, leaving a remainder of 11.
The next digit of our result is 8. 
Result so far: 68.0
Subtract 792 from 803 to get 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 99

Advancing to step 5:
118 divided by 99 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 681.0
Deduct 99 from 118 and we're left with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 99

Going ahead to step 6:
99 goes into 198 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 6812.0
Subtract 198 from 198 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.

Going ahead to step 7:
The number 99 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6812.0
Deduct 0 from 0 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.

Going ahead to step 8:
If we divide 0 by 99, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6812.0
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.

The final outcome is 6812.0, with a leftover of 0.0.
