Let's divide 31303 by 89
We want to divide 31303 by 89.

On to step 1:
When dividing 3 by 89, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 89

Moving on to step 2:
89 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Bring next digit (3) of the dividend behind the 31 and repeat the process: 313 / 89

Step 3:
The number 89 fits into 313 3 times, leaving a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 267 from 313 to get 46.
Append the next digit (0) from the dividend to 46 and continue with: 460 / 89

On to step 4:
89 can be fit into 460 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 35.0
If we subtract 445 from 460, we get 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 89

Let's proceed to step 5:
If we divide 153 by 89, we get 1 and a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 351.0
If we take 89 away from 153, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 6:
When dividing 640 by 89, we get 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 351.7
Deduct 623 from 640 and we're left 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.

Going ahead to step 7:
When dividing 170 by 89, we get 1 with a remainder of 81.
Put 1 as the next digit of the answer. 
Result so far: 351.71
Subtract 89 from 170 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 8:
89 can be fit into 810 9 times, resulting in a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 351.719
Deduct 801 from 810 and we're left 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.

Going ahead to step 9:
90 divided by 89 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 351.7191
If we subtract 89 from 90, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 10:
If we divide 10 by 89, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 351.7191
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
The number 89 fits into 100 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 351.719101
Subtracting 89 from 100 leaves us 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.

Moving on to step 12:
89 goes into 110 1 times with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 351.7191011
The remainder is 21 after subtracting 89 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The quotient of the division is 351.7191011, and the remainder is 2.1e-07.
