We look at the division of 20428541 by 998 
We're looking to find how many times 998 goes into 20428541.

Going ahead to step 1:
998 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 998

Going ahead to step 2:
20 divided by 998 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 998

Going ahead to step 3:
When dividing 204 by 998, we get 0 with a remainder of 204.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 204 and we're left with 204.
Fetch the next digit (2) from the dividend, attach it to 204 and continue: 2042 / 998

Step 4:
When dividing 2042 by 998, we get 2 with a remainder of 46.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1996 from 2042 to get 46.
Grab the next digit (8) from the dividend, add it to 46, then carry on: 468 / 998

Step 5:
468 divided by 998 is 0 with a remainder of 468.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
The remainder is 468 after subtracting 0 from 468.
Grab the next digit (5) from the dividend, add it to 468, then carry on: 4685 / 998

Moving on to step 6:
If we divide 4685 by 998, we get 4 and a remainder of 693.
Use 4 as the next digit of our solution. 
Result so far: 204.0
Subtracting 3992 from 4685 leaves us with 693.
Grab the next digit (4) from the dividend, add it to 693, then carry on: 6934 / 998

Moving on to step 7:
998 goes into 6934 6 times with a remainder of 946.
The next digit of our result is 6. 
Result so far: 2046.0
If we subtract 5988 from 6934, we get 946.
Include the next digit (1) from the dividend after 946, then repeat: 9461 / 998

Advancing to step 8:
998 goes into 9461 9 times with a remainder of 479.
The number 9 becomes the next digit in our result. 
Result so far: 20469.0
The remainder is 479 after subtracting 8982 from 9461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Moving on to step 9:
998 can be fit into 4790 4 times, resulting in a remainder of 798.
The number 4 becomes the next digit in our result. 
Result so far: 20469.4
Deduct 3992 from 4790 and we're left with 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Moving on to step 10:
998 goes into 7980 7 times with a remainder of 994.
Write down 7 as next digit of the result. 
Result so far: 20469.47
The remainder is 994 after subtracting 6986 from 7980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9940, and continue the process.

Step 11:
If we divide 9940 by 998, we get 9 and a remainder of 958.
The next digit of our result is 9. 
Result so far: 20469.479
The remainder is 958 after subtracting 8982 from 9940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9580, and continue the process.

Let's proceed to step 12:
998 can be fit into 9580 9 times, resulting in a remainder of 598.
Put 9 as the next digit of the answer. 
Result so far: 20469.4799
If we take 8982 away from 9580, we end up with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

The final outcome is 20469.4799, with a leftover of 0.00598.
