248661 ÷ 86 
Let's see how many times 86 fits into 248661.

Moving on to step 1:
When dividing 2 by 86, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 86

Let's proceed to step 2:
When dividing 24 by 86, we get 0 with a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 24, we get 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 86

Step 3:
The number 86 fits into 248 2 times, leaving a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 172 away from 248, we end up with 76.
Fetch the next digit (6) from the dividend, attach it to 76 and continue: 766 / 86

Let's proceed to step 4:
86 goes into 766 8 times with a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
The remainder is 78 after subtracting 688 from 766.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 86

Advancing to step 5:
If we divide 786 by 86, we get 9 and a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 289.0
If we take 774 away from 786, we end up with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 86

Moving on to step 6:
86 can be fit into 121 1 times, resulting in a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 2891.0
Subtracting 86 from 121 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 7:
The number 86 fits into 350 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 2891.4
The remainder is 6 after subtracting 344 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
86 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 2891.4
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
When dividing 600 by 86, we get 6 with a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 2891.406
Deduct 516 from 600 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 10:
The number 86 fits into 840 9 times, leaving a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 2891.4069
If we take 774 away from 840, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 11:
When dividing 660 by 86, we get 7 with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 2891.40697
Subtract 602 from 660 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 12:
86 can be fit into 580 6 times, resulting in a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 2891.406976
The remainder is 64 after subtracting 516 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 13:
86 goes into 640 7 times with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 2891.4069767
Subtracting 602 from 640 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 14:
86 can be fit into 380 4 times, resulting in a remainder of 36.
The next digit of our result is 4. 
Result so far: 2891.40697674
The remainder is 36 after subtracting 344 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 2891.40697674 with a remainder of 3.6e-08.
