97855 ÷ 31 
Let's see how many times 31 fits into 97855.

Let's proceed to step 1:
31 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 31

Going ahead to step 2:
31 goes into 97 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 93 from 97, we get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 31

Advancing to step 3:
31 goes into 48 1 times with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Deduct 31 from 48 and we're left with 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 31

Going ahead to step 4:
The number 31 fits into 175 5 times, leaving a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 315.0
Subtract 155 from 175 to get 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 31

Advancing to step 5:
31 goes into 205 6 times with a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 3156.0
Deduct 186 from 205 and we're left with 19.
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 6:
31 can be fit into 190 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 3156.6
If we take 186 away from 190, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
40 divided by 31 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 3156.61
If we subtract 31 from 40, we get 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 8:
31 goes into 90 2 times with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 3156.612
The remainder is 28 after subtracting 62 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
31 can be fit into 280 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 3156.6129
The remainder is 1 after subtracting 279 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
10 divided by 31 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 3156.6129
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.

Step 11:
31 can be fit into 100 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 3156.612903
Deduct 93 from 100 and we're left 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.

Step 12:
The number 31 fits into 70 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 3156.6129032
If we take 62 away from 70, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
The number 31 fits into 80 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 3156.61290322
If we subtract 62 from 80, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 3156.61290322, with a leftover of 1.8e-08.
