908187 ÷ 31 
Our goal is to divide 908187 by 31.

On to step 1:
9 divided by 31 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 31

Advancing to step 2:
When dividing 90 by 31, we get 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 28 after subtracting 62 from 90.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 31

Advancing to step 3:
31 goes into 288 9 times with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
The remainder is 9 after subtracting 279 from 288.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 31

On to step 4:
If we divide 91 by 31, we get 2 and a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 292.0
Subtracting 62 from 91 leaves us with 29.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 31

Moving on to step 5:
The number 31 fits into 298 9 times, leaving a remainder of 19.
The next digit of our result is 9. 
Result so far: 2929.0
Subtracting 279 from 298 leaves us with 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 31

Step 6:
31 can be fit into 197 6 times, resulting in a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 29296.0
Deduct 186 from 197 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
The number 31 fits into 110 3 times, leaving a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 29296.3
If we take 93 away from 110, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
The number 31 fits into 170 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 29296.35
Deduct 155 from 170 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
31 goes into 150 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 29296.354
Deduct 124 from 150 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 10:
The number 31 fits into 260 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 29296.3548
Subtract 248 from 260 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
31 can be fit into 120 3 times, resulting in a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 29296.35483
Subtracting 93 from 120 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 12:
31 goes into 270 8 times with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 29296.354838
If we subtract 248 from 270, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 13:
31 goes into 220 7 times with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 29296.3548387
Subtracting 217 from 220 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
31 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 29296.3548387
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 29296.3548387 and a remainder of 3e-08.
