Let's divide 310287 by 89
We want to figure out the number of times 310287 can be divided by 89.

Step 1:
When dividing 3 by 89, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 89

Moving on to step 2:
When dividing 31 by 89, we get 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Include the next digit (0) from the dividend after 31, then repeat: 310 / 89

Step 3:
89 can be fit into 310 3 times, resulting in a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 43 after subtracting 267 from 310.
Append the next digit (2) from the dividend to 43 and continue with: 432 / 89

Let's proceed to step 4:
When dividing 432 by 89, we get 4 with a remainder of 76.
The next digit of our result is 4. 
Result so far: 34.0
If we subtract 356 from 432, we get 76.
Append the next digit (8) from the dividend to 76 and continue with: 768 / 89

Step 5:
The number 89 fits into 768 8 times, leaving a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 348.0
If we take 712 away from 768, we end up with 56.
Take the next digit (7) from the dividend and append it to 56, then repeat: 567 / 89

Going ahead to step 6:
When dividing 567 by 89, we get 6 with a remainder of 33.
Write down 6 as next digit of the result. 
Result so far: 3486.0
The remainder is 33 after subtracting 534 from 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
330 divided by 89 is 3 with a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 3486.3
If we subtract 267 from 330, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 8:
The number 89 fits into 630 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 3486.37
If we take 623 away from 630, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
If we divide 70 by 89, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 3486.37
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
89 goes into 700 7 times with a remainder of 77.
Put 7 as the next digit of the answer. 
Result so far: 3486.3707
Subtracting 623 from 700 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 11:
89 goes into 770 8 times with a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 3486.37078
If we subtract 712 from 770, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 12:
89 can be fit into 580 6 times, resulting in a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 3486.370786
Subtracting 534 from 580 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 13:
If we divide 460 by 89, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 3486.3707865
Subtracting 445 from 460 leaves us 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.

On to step 14:
The number 89 fits into 150 1 times, leaving a remainder of 61.
The next digit of our result is 1. 
Result so far: 3486.37078651
Deduct 89 from 150 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

After the division, we end up with 3486.37078651 and a remainder of 6.1e-08.
