15288918 ÷ 998 
We want to divide 15288918 by 998.

Moving on to step 1:
1 divided by 998 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 998

Advancing to step 2:
If we divide 15 by 998, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 998

Going ahead to step 3:
If we divide 152 by 998, we get 0 and a remainder of 152.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 152 to get 152.
Take the next digit (8) from the dividend and append it to 152, then repeat: 1528 / 998

Step 4:
If we divide 1528 by 998, we get 1 and a remainder of 530.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 998 from 1528 and we're left with 530.
Bring next digit (8) of the dividend behind the 530 and repeat the process: 5308 / 998

Let's proceed to step 5:
If we divide 5308 by 998, we get 5 and a remainder of 318.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 4990 from 5308 and we're left with 318.
Bring next digit (9) of the dividend behind the 318 and repeat the process: 3189 / 998

Going ahead to step 6:
998 can be fit into 3189 3 times, resulting in a remainder of 195.
Record the quotient 3 as the next digit in the result. 
Result so far: 153.0
The remainder is 195 after subtracting 2994 from 3189.
Fetch the next digit (1) from the dividend, attach it to 195 and continue: 1951 / 998

Moving on to step 7:
The number 998 fits into 1951 1 times, leaving a remainder of 953.
Use 1 as the next digit of our solution. 
Result so far: 1531.0
Deduct 998 from 1951 and we're left with 953.
Grab the next digit (8) from the dividend, add it to 953, then carry on: 9538 / 998

Advancing to step 8:
998 can be fit into 9538 9 times, resulting in a remainder of 556.
The next digit of our result is 9. 
Result so far: 15319.0
If we take 8982 away from 9538, we end up with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Moving on to step 9:
998 goes into 5560 5 times with a remainder of 570.
Put 5 as the next digit of the answer. 
Result so far: 15319.5
The remainder is 570 after subtracting 4990 from 5560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 10:
If we divide 5700 by 998, we get 5 and a remainder of 710.
The number 5 becomes the next digit in our result. 
Result so far: 15319.55
Subtracting 4990 from 5700 leaves us with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

After the division, we end up with 15319.55 and a remainder of 0.71.
