988331 ÷ 31 
We want to figure out the number of times 988331 can be divided by 31.

Let's proceed to step 1:
The number 31 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 31

Advancing to step 2:
98 divided by 31 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 93 away from 98, we end up with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 31

Going ahead to step 3:
58 divided by 31 is 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtracting 31 from 58 leaves us with 27.
Append the next digit (3) from the dividend to 27 and continue with: 273 / 31

Going ahead to step 4:
273 divided by 31 is 8 with a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 318.0
If we subtract 248 from 273, we get 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 31

Moving on to step 5:
31 goes into 253 8 times with a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 3188.0
Subtracting 248 from 253 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 31

Step 6:
31 goes into 51 1 times with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 31881.0
If we subtract 31 from 51, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
200 divided by 31 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 31881.6
Subtract 186 from 200 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
The number 31 fits into 140 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 31881.64
The remainder is 16 after subtracting 124 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
If we divide 160 by 31, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 31881.645
If we subtract 155 from 160, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
If we divide 50 by 31, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 31881.6451
The remainder is 19 after subtracting 31 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 11:
If we divide 190 by 31, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 31881.64516
Subtract 186 from 190 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
When dividing 40 by 31, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 31881.645161
Subtracting 31 from 40 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
When dividing 90 by 31, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 31881.6451612
Deduct 62 from 90 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 14:
The number 31 fits into 280 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 31881.64516129
If we take 279 away from 280, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 31881.64516129 and a remainder of 1e-09.
