213599 divided by 87 
We want to divide 213599 by 87.

Moving on to step 1:
87 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 87

Going ahead to step 2:
The number 87 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 87

Moving on to step 3:
213 divided by 87 is 2 with a remainder of 39.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 174 from 213 and we're left with 39.
Append the next digit (5) from the dividend to 39 and continue with: 395 / 87

Step 4:
If we divide 395 by 87, we get 4 and a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we subtract 348 from 395, we get 47.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 87

Step 5:
87 goes into 479 5 times with a remainder of 44.
The next digit of our result is 5. 
Result so far: 245.0
Subtract 435 from 479 to get 44.
Bring next digit (9) of the dividend behind the 44 and repeat the process: 449 / 87

Advancing to step 6:
The number 87 fits into 449 5 times, leaving a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 2455.0
The remainder is 14 after subtracting 435 from 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
The number 87 fits into 140 1 times, leaving a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 2455.1
Deduct 87 from 140 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 8:
530 divided by 87 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 2455.16
If we take 522 away from 530, 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.

Moving on to step 9:
If we divide 80 by 87, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 2455.16
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.

Let's proceed to step 10:
87 goes into 800 9 times with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 2455.1609
If we take 783 away from 800, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 11:
If we divide 170 by 87, we get 1 and a remainder of 83.
The number 1 becomes the next digit in our result. 
Result so far: 2455.16091
Deduct 87 from 170 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 12:
When dividing 830 by 87, we get 9 with a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 2455.160919
Subtracting 783 from 830 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 13:
When dividing 470 by 87, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 2455.1609195
The remainder is 35 after subtracting 435 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 14:
If we divide 350 by 87, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 2455.16091954
If we subtract 348 from 350, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 2455.16091954 with a balance of 2e-09.
