98340558 ÷ 999 
We're looking to find how many times 999 goes into 98340558.

Let's proceed to step 1:
999 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 999

Step 2:
98 divided by 999 is 0 with a remainder of 98.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 98, we end up with 98.
Fetch the next digit (3) from the dividend, attach it to 98 and continue: 983 / 999

Let's proceed to step 3:
The number 999 fits into 983 0 times, leaving a remainder of 983.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 983 leaves us with 983.
Bring next digit (4) of the dividend behind the 983 and repeat the process: 9834 / 999

On to step 4:
When dividing 9834 by 999, we get 9 with a remainder of 843.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 8991 from 9834 leaves us with 843.
Bring next digit (0) of the dividend behind the 843 and repeat the process: 8430 / 999

Moving on to step 5:
8430 divided by 999 is 8 with a remainder of 438.
Put 8 as the next digit of the answer. 
Result so far: 98.0
Subtracting 7992 from 8430 leaves us with 438.
Grab the next digit (5) from the dividend, add it to 438, then carry on: 4385 / 999

Let's proceed to step 6:
When dividing 4385 by 999, we get 4 with a remainder of 389.
The next digit of our result is 4. 
Result so far: 984.0
If we subtract 3996 from 4385, we get 389.
Include the next digit (5) from the dividend after 389, then repeat: 3895 / 999

Advancing to step 7:
999 can be fit into 3895 3 times, resulting in a remainder of 898.
Use 3 as the next digit of our solution. 
Result so far: 9843.0
The remainder is 898 after subtracting 2997 from 3895.
Append the next digit (8) from the dividend to 898 and continue with: 8988 / 999

Let's proceed to step 8:
8988 divided by 999 is 8 with a remainder of 996.
Use 8 as the next digit of our solution. 
Result so far: 98438.0
If we subtract 7992 from 8988, we get 996.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9960, and continue the process.

Going ahead to step 9:
If we divide 9960 by 999, we get 9 and a remainder of 969.
The number 9 becomes the next digit in our result. 
Result so far: 98438.9
The remainder is 969 after subtracting 8991 from 9960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9690, and continue the process.

On to step 10:
When dividing 9690 by 999, we get 9 with a remainder of 699.
The next digit of our result is 9. 
Result so far: 98438.99
Subtract 8991 from 9690 to get 699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Our division results in 98438.99 with a remaining 0.699.
