289512 ÷ 87 
We want to figure out the number of times 289512 can be divided by 87.

Let's proceed to step 1:
87 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 87

Moving on to step 2:
When dividing 28 by 87, we get 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Fetch the next digit (9) from the dividend, attach it to 28 and continue: 289 / 87

On to step 3:
The number 87 fits into 289 3 times, leaving a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 261 away from 289, we end up with 28.
Fetch the next digit (5) from the dividend, attach it to 28 and continue: 285 / 87

On to step 4:
The number 87 fits into 285 3 times, leaving a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtracting 261 from 285 leaves us with 24.
Bring next digit (1) of the dividend behind the 24 and repeat the process: 241 / 87

Step 5:
241 divided by 87 is 2 with a remainder of 67.
Write down 2 as next digit of the result. 
Result so far: 332.0
If we take 174 away from 241, we end up with 67.
Fetch the next digit (2) from the dividend, attach it to 67 and continue: 672 / 87

Step 6:
The number 87 fits into 672 7 times, leaving a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 3327.0
If we take 609 away from 672, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 7:
The number 87 fits into 630 7 times, leaving a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 3327.7
If we take 609 away from 630, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 8:
The number 87 fits into 210 2 times, leaving a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 3327.72
The remainder is 36 after subtracting 174 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
360 divided by 87 is 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 3327.724
If we take 348 away from 360, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
87 goes into 120 1 times with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 3327.7241
If we subtract 87 from 120, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 11:
The number 87 fits into 330 3 times, leaving a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 3327.72413
Deduct 261 from 330 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 12:
The number 87 fits into 690 7 times, leaving a remainder of 81.
Use 7 as the next digit of our solution. 
Result so far: 3327.724137
The remainder is 81 after subtracting 609 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 13:
When dividing 810 by 87, we get 9 with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 3327.7241379
If we take 783 away from 810, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 14:
87 can be fit into 270 3 times, resulting in a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3327.72413793
If we subtract 261 from 270, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 3327.72413793, with a leftover of 9e-09.
