We divide 971386 by 31
We want to divide 971386 by 31.

Step 1:
31 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 31

Step 2:
31 can be fit into 97 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 93 from 97 and we're left with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 31

Step 3:
41 divided by 31 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtract 31 from 41 to get 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 31

Advancing to step 4:
31 goes into 103 3 times with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 313.0
If we take 93 away from 103, we end up with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 31

Step 5:
When dividing 108 by 31, we get 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 3133.0
The remainder is 15 after subtracting 93 from 108.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 31

Moving on to step 6:
The number 31 fits into 156 5 times, leaving a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 31335.0
If we subtract 155 from 156, 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.

Let's proceed to step 7:
31 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 31335.0
If we subtract 0 from 10, we 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 8:
If we divide 100 by 31, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 31335.03
Subtracting 93 from 100 leaves us 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.

Going ahead to step 9:
The number 31 fits into 70 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 31335.032
If we subtract 62 from 70, we get 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 10:
80 divided by 31 is 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 31335.0322
Subtracting 62 from 80 leaves us with 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 result is 31335.0322 with a remainder of 0.00018.
