91658 ÷ 31 
Let's see how many times 31 fits into 91658.

Moving on to step 1:
31 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 31

Moving on to step 2:
91 divided by 31 is 2 with a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 62 away from 91, we end up with 29.
Append the next digit (6) from the dividend to 29 and continue with: 296 / 31

Going ahead to step 3:
31 goes into 296 9 times with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we subtract 279 from 296, we get 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 31

Going ahead to step 4:
If we divide 175 by 31, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 295.0
If we subtract 155 from 175, we get 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 31

On to step 5:
208 divided by 31 is 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 2956.0
If we subtract 186 from 208, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 6:
When dividing 220 by 31, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 2956.7
Deduct 217 from 220 and we're left with 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 7:
When dividing 30 by 31, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 2956.7
Subtract 0 from 30 to 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.

Going ahead to step 8:
300 divided by 31 is 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 2956.709
If we subtract 279 from 300, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
When dividing 210 by 31, we get 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 2956.7096
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.

Moving on to step 10:
31 goes into 240 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 2956.70967
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.

Step 11:
The number 31 fits into 230 7 times, leaving a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 2956.709677
If we take 217 away from 230, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 2956.709677 and a remainder of 1.3e-06.
