We're dividing 221429 by 87 
We want to figure out the number of times 221429 can be divided by 87.

On to step 1:
The number 87 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 87

Advancing to step 2:
If we divide 22 by 87, we get 0 and a remainder of 22.
Write down 0 as next digit of the result. 
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 / 87

Moving on to step 3:
The number 87 fits into 221 2 times, leaving a remainder of 47.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 174 from 221 to get 47.
Take the next digit (4) from the dividend and append it to 47, then repeat: 474 / 87

On to step 4:
474 divided by 87 is 5 with a remainder of 39.
The next digit of our result is 5. 
Result so far: 25.0
If we subtract 435 from 474, we get 39.
Append the next digit (2) from the dividend to 39 and continue with: 392 / 87

Advancing to step 5:
The number 87 fits into 392 4 times, leaving a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 254.0
If we subtract 348 from 392, we get 44.
Bring next digit (9) of the dividend behind the 44 and repeat the process: 449 / 87

Step 6:
If we divide 449 by 87, we get 5 and a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 2545.0
Subtracting 435 from 449 leaves us with 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 7:
87 can be fit into 140 1 times, resulting in a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 2545.1
If we take 87 away from 140, we end up 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.

Let's proceed to step 8:
87 can be fit into 530 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 2545.16
Subtracting 522 from 530 leaves us 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.

Going ahead to step 9:
87 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 2545.16
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.

On to step 10:
If we divide 800 by 87, we get 9 and a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 2545.1609
Subtracting 783 from 800 leaves us 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.

Step 11:
The number 87 fits into 170 1 times, leaving a remainder of 83.
The number 1 becomes the next digit in our result. 
Result so far: 2545.16091
Subtract 87 from 170 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 12:
87 can be fit into 830 9 times, resulting in a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 2545.160919
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.

Moving on to step 13:
87 goes into 470 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 2545.1609195
Subtracting 435 from 470 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.

Advancing to step 14:
350 divided by 87 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 2545.16091954
The remainder is 2 after subtracting 348 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 2545.16091954 with a remainder of 2e-09.
