121271 divided by 87 
We want to figure out the number of times 121271 can be divided by 87.

Step 1:
The number 87 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 87

Step 2:
12 divided by 87 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 87

Advancing to step 3:
87 goes into 121 1 times with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 34 after subtracting 87 from 121.
Fetch the next digit (2) from the dividend, attach it to 34 and continue: 342 / 87

Moving on to step 4:
342 divided by 87 is 3 with a remainder of 81.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 81 after subtracting 261 from 342.
Take the next digit (7) from the dividend and append it to 81, then repeat: 817 / 87

Let's proceed to step 5:
87 can be fit into 817 9 times, resulting in a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 139.0
The remainder is 34 after subtracting 783 from 817.
Take the next digit (1) from the dividend and append it to 34, then repeat: 341 / 87

Advancing to step 6:
341 divided by 87 is 3 with a remainder of 80.
Record the quotient 3 as the next digit in the result. 
Result so far: 1393.0
The remainder is 80 after subtracting 261 from 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 7:
87 can be fit into 800 9 times, resulting in a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 1393.9
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 8:
87 can be fit into 170 1 times, resulting in a remainder of 83.
Write down 1 as next digit of the result. 
Result so far: 1393.91
If we subtract 87 from 170, we 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.

Going ahead to step 9:
The number 87 fits into 830 9 times, leaving a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 1393.919
Subtract 783 from 830 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 10:
87 can be fit into 470 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 1393.9195
Subtract 435 from 470 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 11:
The number 87 fits into 350 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 1393.91954
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.

On to step 12:
20 divided by 87 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 1393.91954
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
If we divide 200 by 87, we get 2 and a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 1393.9195402
The remainder is 26 after subtracting 174 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 14:
When dividing 260 by 87, we get 2 with a remainder of 86.
Use 2 as the next digit of our solution. 
Result so far: 1393.91954022
If we subtract 174 from 260, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

After the division, we end up with 1393.91954022 and a remainder of 8.6e-08.
