We're dividing 30997 by 86 
We want to figure out the number of times 30997 can be divided by 86.

On to step 1:
3 divided by 86 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 86

Step 2:
30 divided by 86 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 86

Step 3:
86 can be fit into 309 3 times, resulting in a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 258 from 309 and we're left with 51.
Take the next digit (9) from the dividend and append it to 51, then repeat: 519 / 86

Advancing to step 4:
519 divided by 86 is 6 with a remainder of 3.
The next digit of our result is 6. 
Result so far: 36.0
Deduct 516 from 519 and we're left with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 86

Advancing to step 5:
86 can be fit into 37 0 times, resulting in a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 360.0
Subtracting 0 from 37 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 6:
The number 86 fits into 370 4 times, leaving a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 360.4
Deduct 344 from 370 and we're left with 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 7:
86 can be fit into 260 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 360.43
Subtracting 258 from 260 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
The number 86 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 360.43
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
When dividing 200 by 86, we get 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 360.4302
Subtracting 172 from 200 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
280 divided by 86 is 3 with a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 360.43023
Subtracting 258 from 280 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.

Going ahead to step 11:
86 can be fit into 220 2 times, resulting in a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 360.430232
Subtracting 172 from 220 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
480 divided by 86 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 360.4302325
Subtracting 430 from 480 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
When dividing 500 by 86, we get 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 360.43023255
Subtract 430 from 500 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 360.43023255 with a balance of 7e-08.
