99038231 ÷ 998 
Let's see how many times 998 fits into 99038231.

Going ahead to step 1:
If we divide 9 by 998, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 998

Going ahead to step 2:
When dividing 99 by 998, we get 0 with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Fetch the next digit (0) from the dividend, attach it to 99 and continue: 990 / 998

Going ahead to step 3:
If we divide 990 by 998, we get 0 and a remainder of 990.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 990 leaves us with 990.
Include the next digit (3) from the dividend after 990, then repeat: 9903 / 998

On to step 4:
If we divide 9903 by 998, we get 9 and a remainder of 921.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 8982 from 9903 to get 921.
Include the next digit (8) from the dividend after 921, then repeat: 9218 / 998

Let's proceed to step 5:
The number 998 fits into 9218 9 times, leaving a remainder of 236.
Write down 9 as next digit of the result. 
Result so far: 99.0
Subtract 8982 from 9218 to get 236.
Append the next digit (2) from the dividend to 236 and continue with: 2362 / 998

Advancing to step 6:
When dividing 2362 by 998, we get 2 with a remainder of 366.
Put 2 as the next digit of the answer. 
Result so far: 992.0
Subtracting 1996 from 2362 leaves us with 366.
Include the next digit (3) from the dividend after 366, then repeat: 3663 / 998

Advancing to step 7:
When dividing 3663 by 998, we get 3 with a remainder of 669.
Put 3 as the next digit of the answer. 
Result so far: 9923.0
Deduct 2994 from 3663 and we're left with 669.
Bring next digit (1) of the dividend behind the 669 and repeat the process: 6691 / 998

On to step 8:
If we divide 6691 by 998, we get 6 and a remainder of 703.
The number 6 becomes the next digit in our result. 
Result so far: 99236.0
The remainder is 703 after subtracting 5988 from 6691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

Going ahead to step 9:
If we divide 7030 by 998, we get 7 and a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 99236.7
Deduct 6986 from 7030 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
998 can be fit into 440 0 times, resulting in a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 99236.7
If we subtract 0 from 440, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 11:
998 goes into 4400 4 times with a remainder of 408.
Write down 4 as next digit of the result. 
Result so far: 99236.704
Subtracting 3992 from 4400 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 12:
The number 998 fits into 4080 4 times, leaving a remainder of 88.
Record the quotient 4 as the next digit in the result. 
Result so far: 99236.7044
If we take 3992 away from 4080, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The quotient of the division is 99236.7044, and the remainder is 0.00088.
