97211 ÷ 31 
Let's see how many times 31 fits into 97211.

Step 1:
9 divided by 31 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 31

Moving on to step 2:
The number 31 fits into 97 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 93 from 97 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 31

Moving on to step 3:
42 divided by 31 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 31 from 42 and we're left with 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 31

Let's proceed to step 4:
111 divided by 31 is 3 with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 313.0
If we subtract 93 from 111, we get 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 31

On to step 5:
31 goes into 181 5 times with a remainder of 26.
The number 5 becomes the next digit in our result. 
Result so far: 3135.0
Subtract 155 from 181 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 6:
31 goes into 260 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 3135.8
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.

Moving on to step 7:
31 can be fit into 120 3 times, resulting in a remainder of 27.
The next digit of our result is 3. 
Result so far: 3135.83
The remainder is 27 after subtracting 93 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 8:
31 goes into 270 8 times with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 3135.838
Subtracting 248 from 270 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
When dividing 220 by 31, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 3135.8387
If we subtract 217 from 220, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
30 divided by 31 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 3135.8387
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
If we divide 300 by 31, we get 9 and a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 3135.838709
The remainder is 21 after subtracting 279 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 12:
When dividing 210 by 31, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 3135.8387096
If we take 186 away from 210, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
If we divide 240 by 31, we get 7 and a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 3135.83870967
If we take 217 away from 240, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 3135.83870967, with a leftover of 2.3e-08.
