216901 divided by 86 
Our goal is to divide 216901 by 86.

On to step 1:
2 divided by 86 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 86

Let's proceed to step 2:
86 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 86

Advancing to step 3:
The number 86 fits into 216 2 times, leaving a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 172 away from 216, we end up with 44.
Append the next digit (9) from the dividend to 44 and continue with: 449 / 86

Let's proceed to step 4:
86 can be fit into 449 5 times, resulting in a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we take 430 away from 449, we end up with 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 86

Going ahead to step 5:
When dividing 190 by 86, we get 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 252.0
If we take 172 away from 190, we end up with 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 86

Going ahead to step 6:
181 divided by 86 is 2 with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 2522.0
Subtracting 172 from 181 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
90 divided by 86 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 2522.1
Deduct 86 from 90 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
If we divide 40 by 86, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 2522.1
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
86 can be fit into 400 4 times, resulting in a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 2522.104
The remainder is 56 after subtracting 344 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
560 divided by 86 is 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 2522.1046
If we take 516 away from 560, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
86 goes into 440 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 2522.10465
Subtracting 430 from 440 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
The number 86 fits into 100 1 times, leaving a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 2522.104651
If we subtract 86 from 100, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
If we divide 140 by 86, we get 1 and a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 2522.1046511
If we take 86 away from 140, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 2522.1046511 and a remainder of 5.4e-07.
