115591 divided by 31 
We want to figure out the number of times 115591 can be divided by 31.

Step 1:
1 divided by 31 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 31

Step 2:
The number 31 fits into 11 0 times, leaving a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 31

Step 3:
If we divide 115 by 31, we get 3 and a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 93 from 115 and we're left with 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 31

Moving on to step 4:
31 can be fit into 225 7 times, resulting in a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtract 217 from 225 to get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 31

Let's proceed to step 5:
When dividing 89 by 31, we get 2 with a remainder of 27.
Record the quotient 2 as the next digit in the result. 
Result so far: 372.0
Deduct 62 from 89 and we're left with 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 31

Going ahead to step 6:
When dividing 271 by 31, we get 8 with a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 3728.0
The remainder is 23 after subtracting 248 from 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
31 goes into 230 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 3728.7
Deduct 217 from 230 and we're left 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.

Let's proceed to step 8:
When dividing 130 by 31, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 3728.74
If we subtract 124 from 130, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
31 can be fit into 60 1 times, resulting in a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 3728.741
Subtract 31 from 60 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 10:
The number 31 fits into 290 9 times, leaving a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 3728.7419
If we subtract 279 from 290, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 11:
31 can be fit into 110 3 times, resulting in a remainder of 17.
The next digit of our result is 3. 
Result so far: 3728.74193
If we subtract 93 from 110, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 12:
31 goes into 170 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 3728.741935
Subtracting 155 from 170 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
When dividing 150 by 31, we get 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 3728.7419354
If we subtract 124 from 150, we 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.

Moving on to step 14:
The number 31 fits into 260 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 3728.74193548
If we subtract 248 from 260, we 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.

In conclusion, the division gives 3728.74193548 with a balance of 1.2e-08.
