221558 divided by 86 
We want to figure out the number of times 221558 can be divided by 86.

Advancing to step 1:
86 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 86

Let's proceed to step 2:
When dividing 22 by 86, we get 0 with a remainder of 22.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 86

Let's proceed to step 3:
The number 86 fits into 221 2 times, leaving a remainder of 49.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 172 from 221, we get 49.
Bring next digit (5) of the dividend behind the 49 and repeat the process: 495 / 86

Going ahead to step 4:
If we divide 495 by 86, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 25.0
If we take 430 away from 495, we end up with 65.
Take the next digit (5) from the dividend and append it to 65, then repeat: 655 / 86

On to step 5:
86 can be fit into 655 7 times, resulting in a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 257.0
If we subtract 602 from 655, we get 53.
Fetch the next digit (8) from the dividend, attach it to 53 and continue: 538 / 86

Advancing to step 6:
86 can be fit into 538 6 times, resulting in a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 2576.0
If we take 516 away from 538, we end up 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 7:
86 goes into 220 2 times with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 2576.2
Deduct 172 from 220 and we're left 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.

Advancing to step 8:
86 goes into 480 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 2576.25
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 9:
500 divided by 86 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 2576.255
The remainder is 70 after subtracting 430 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 2576.255 and a remainder of 0.007.
