We look at the division of 988928 by 31 
We want to figure out the number of times 988928 can be divided by 31.

Step 1:
The number 31 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 31

On to step 2:
31 goes into 98 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 93 from 98 leaves us with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 31

Step 3:
58 divided by 31 is 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Deduct 31 from 58 and we're left with 27.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 31

Moving on to step 4:
The number 31 fits into 279 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 319.0
If we subtract 279 from 279, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 31

Going ahead to step 5:
31 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 3190.0
If we subtract 0 from 2, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 31

Moving on to step 6:
The number 31 fits into 28 0 times, leaving a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 31900.0
Deduct 0 from 28 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
The number 31 fits into 280 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 31900.9
The remainder is 1 after subtracting 279 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
The number 31 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 31900.9
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
If we divide 100 by 31, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 31900.903
Subtract 93 from 100 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
70 divided by 31 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 31900.9032
If we take 62 away from 70, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
80 divided by 31 is 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 31900.90322
Subtract 62 from 80 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 31900.90322 with a remaining 1.8e-05.
