43135501 ÷ 998 
Let's see how many times 998 fits into 43135501.

Moving on to step 1:
998 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 998

Going ahead to step 2:
If we divide 43 by 998, we get 0 and a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 998

On to step 3:
The number 998 fits into 431 0 times, leaving a remainder of 431.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 431, we get 431.
Include the next digit (3) from the dividend after 431, then repeat: 4313 / 998

Step 4:
998 goes into 4313 4 times with a remainder of 321.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 3992 from 4313 and we're left with 321.
Append the next digit (5) from the dividend to 321 and continue with: 3215 / 998

Let's proceed to step 5:
If we divide 3215 by 998, we get 3 and a remainder of 221.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
The remainder is 221 after subtracting 2994 from 3215.
Append the next digit (5) from the dividend to 221 and continue with: 2215 / 998

Step 6:
The number 998 fits into 2215 2 times, leaving a remainder of 219.
Use 2 as the next digit of our solution. 
Result so far: 432.0
Subtract 1996 from 2215 to get 219.
Include the next digit (0) from the dividend after 219, then repeat: 2190 / 998

Going ahead to step 7:
2190 divided by 998 is 2 with a remainder of 194.
The number 2 becomes the next digit in our result. 
Result so far: 4322.0
The remainder is 194 after subtracting 1996 from 2190.
Bring next digit (1) of the dividend behind the 194 and repeat the process: 1941 / 998

Step 8:
1941 divided by 998 is 1 with a remainder of 943.
Write down 1 as next digit of the result. 
Result so far: 43221.0
Subtract 998 from 1941 to get 943.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9430, and continue the process.

Let's proceed to step 9:
The number 998 fits into 9430 9 times, leaving a remainder of 448.
The number 9 becomes the next digit in our result. 
Result so far: 43221.9
Subtract 8982 from 9430 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 10:
The number 998 fits into 4480 4 times, leaving a remainder of 488.
Use 4 as the next digit of our solution. 
Result so far: 43221.94
The remainder is 488 after subtracting 3992 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Step 11:
4880 divided by 998 is 4 with a remainder of 888.
The number 4 becomes the next digit in our result. 
Result so far: 43221.944
If we subtract 3992 from 4880, we get 888.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8880, and continue the process.

After the division, we end up with 43221.944 and a remainder of 0.0888.
