We're dividing 215634 by 86 
Our goal is to divide 215634 by 86.

Moving on to step 1:
86 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 86

Let's proceed to step 2:
86 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 86

On to step 3:
When dividing 215 by 86, we get 2 with a remainder of 43.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 172 from 215 to get 43.
Append the next digit (6) from the dividend to 43 and continue with: 436 / 86

Moving on to step 4:
The number 86 fits into 436 5 times, leaving a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 25.0
The remainder is 6 after subtracting 430 from 436.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 86

On to step 5:
The number 86 fits into 63 0 times, leaving a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 250.0
If we subtract 0 from 63, we get 63.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 86

Step 6:
634 divided by 86 is 7 with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 2507.0
Deduct 602 from 634 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 7:
86 can be fit into 320 3 times, resulting in a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 2507.3
Subtracting 258 from 320 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 8:
If we divide 620 by 86, we get 7 and a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 2507.37
The remainder is 18 after subtracting 602 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
If we divide 180 by 86, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 2507.372
If we take 172 away from 180, 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.

On to step 10:
80 divided by 86 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 2507.372
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 11:
800 divided by 86 is 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 2507.37209
Subtract 774 from 800 to 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.

Going ahead to step 12:
86 goes into 260 3 times with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 2507.372093
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.

Step 13:
When dividing 20 by 86, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2507.372093
Subtracting 0 from 20 leaves us with 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 14:
200 divided by 86 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 2507.37209302
Subtract 172 from 200 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 2507.37209302 with a remainder of 2.8e-08.
