Let's divide 42400500 by 998
Our goal is to divide 42400500 by 998.

Step 1:
If we divide 4 by 998, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 998

On to step 2:
When dividing 42 by 998, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Append the next digit (4) from the dividend to 42 and continue with: 424 / 998

Advancing to step 3:
If we divide 424 by 998, we get 0 and a remainder of 424.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 424 and we're left with 424.
Take the next digit (0) from the dividend and append it to 424, then repeat: 4240 / 998

Moving on to step 4:
4240 divided by 998 is 4 with a remainder of 248.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 248 after subtracting 3992 from 4240.
Grab the next digit (0) from the dividend, add it to 248, then carry on: 2480 / 998

Going ahead to step 5:
When dividing 2480 by 998, we get 2 with a remainder of 484.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
The remainder is 484 after subtracting 1996 from 2480.
Grab the next digit (5) from the dividend, add it to 484, then carry on: 4845 / 998

Advancing to step 6:
998 can be fit into 4845 4 times, resulting in a remainder of 853.
Record the quotient 4 as the next digit in the result. 
Result so far: 424.0
Subtract 3992 from 4845 to get 853.
Take the next digit (0) from the dividend and append it to 853, then repeat: 8530 / 998

Moving on to step 7:
When dividing 8530 by 998, we get 8 with a remainder of 546.
Put 8 as the next digit of the answer. 
Result so far: 4248.0
Deduct 7984 from 8530 and we're left with 546.
Append the next digit (0) from the dividend to 546 and continue with: 5460 / 998

Advancing to step 8:
998 goes into 5460 5 times with a remainder of 470.
Write down 5 as next digit of the result. 
Result so far: 42485.0
Subtract 4990 from 5460 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 9:
4700 divided by 998 is 4 with a remainder of 708.
Use 4 as the next digit of our solution. 
Result so far: 42485.4
The remainder is 708 after subtracting 3992 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Moving on to step 10:
If we divide 7080 by 998, we get 7 and a remainder of 94.
Write down 7 as next digit of the result. 
Result so far: 42485.47
The remainder is 94 after subtracting 6986 from 7080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 11:
The number 998 fits into 940 0 times, leaving a remainder of 940.
Use 0 as the next digit of our solution. 
Result so far: 42485.47
Subtract 0 from 940 to get 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

Advancing to step 12:
The number 998 fits into 9400 9 times, leaving a remainder of 418.
The next digit of our result is 9. 
Result so far: 42485.4709
Subtracting 8982 from 9400 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Let's proceed to step 13:
If we divide 4180 by 998, we get 4 and a remainder of 188.
The next digit of our result is 4. 
Result so far: 42485.47094
Deduct 3992 from 4180 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 14:
998 goes into 1880 1 times with a remainder of 882.
Record the quotient 1 as the next digit in the result. 
Result so far: 42485.470941
If we subtract 998 from 1880, we get 882.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8820, and continue the process.

Moving on to step 15:
998 can be fit into 8820 8 times, resulting in a remainder of 836.
Use 8 as the next digit of our solution. 
Result so far: 42485.4709418
The remainder is 836 after subtracting 7984 from 8820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

Moving on to step 16:
998 goes into 8360 8 times with a remainder of 376.
Put 8 as the next digit of the answer. 
Result so far: 42485.47094188
Deduct 7984 from 8360 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

In conclusion, the division gives 42485.47094188 with a balance of 3.76e-07.
