We look at the division of 18621755 by 998 
Let's see how many times 998 fits into 18621755.

Step 1:
1 divided by 998 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 998

Advancing to step 2:
When dividing 18 by 998, we get 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 998

Step 3:
998 can be fit into 186 0 times, resulting in a remainder of 186.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 186, we get 186.
Fetch the next digit (2) from the dividend, attach it to 186 and continue: 1862 / 998

Advancing to step 4:
1862 divided by 998 is 1 with a remainder of 864.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 998 from 1862 to get 864.
Fetch the next digit (1) from the dividend, attach it to 864 and continue: 8641 / 998

Let's proceed to step 5:
If we divide 8641 by 998, we get 8 and a remainder of 657.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 7984 from 8641 leaves us with 657.
Append the next digit (7) from the dividend to 657 and continue with: 6577 / 998

Advancing to step 6:
When dividing 6577 by 998, we get 6 with a remainder of 589.
Record the quotient 6 as the next digit in the result. 
Result so far: 186.0
Deduct 5988 from 6577 and we're left with 589.
Include the next digit (5) from the dividend after 589, then repeat: 5895 / 998

On to step 7:
If we divide 5895 by 998, we get 5 and a remainder of 905.
Write down 5 as next digit of the result. 
Result so far: 1865.0
If we take 4990 away from 5895, we end up with 905.
Fetch the next digit (5) from the dividend, attach it to 905 and continue: 9055 / 998

Advancing to step 8:
When dividing 9055 by 998, we get 9 with a remainder of 73.
Write down 9 as next digit of the result. 
Result so far: 18659.0
The remainder is 73 after subtracting 8982 from 9055.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 9:
When dividing 730 by 998, we get 0 with a remainder of 730.
Record the quotient 0 as the next digit in the result. 
Result so far: 18659.0
Subtract 0 from 730 to get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Let's proceed to step 10:
998 can be fit into 7300 7 times, resulting in a remainder of 314.
Write down 7 as next digit of the result. 
Result so far: 18659.07
If we subtract 6986 from 7300, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Advancing to step 11:
When dividing 3140 by 998, we get 3 with a remainder of 146.
Record the quotient 3 as the next digit in the result. 
Result so far: 18659.073
The remainder is 146 after subtracting 2994 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 12:
1460 divided by 998 is 1 with a remainder of 462.
Use 1 as the next digit of our solution. 
Result so far: 18659.0731
Subtracting 998 from 1460 leaves us with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Let's proceed to step 13:
998 can be fit into 4620 4 times, resulting in a remainder of 628.
Put 4 as the next digit of the answer. 
Result so far: 18659.07314
The remainder is 628 after subtracting 3992 from 4620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Let's proceed to step 14:
When dividing 6280 by 998, we get 6 with a remainder of 292.
The next digit of our result is 6. 
Result so far: 18659.073146
Subtract 5988 from 6280 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 15:
2920 divided by 998 is 2 with a remainder of 924.
Write down 2 as next digit of the result. 
Result so far: 18659.0731462
Subtract 1996 from 2920 to get 924.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9240, and continue the process.

Let's proceed to step 16:
When dividing 9240 by 998, we get 9 with a remainder of 258.
The next digit of our result is 9. 
Result so far: 18659.07314629
Subtracting 8982 from 9240 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

After the division, we end up with 18659.07314629 and a remainder of 2.58e-07.
