We look at the division of 261721 by 87 
We want to divide 261721 by 87.

Moving on to step 1:
87 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 87

Let's proceed to step 2:
When dividing 26 by 87, we get 0 with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 87

On to step 3:
87 can be fit into 261 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 261 from 261 and we're left with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 87

Let's proceed to step 4:
The number 87 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 87

Let's proceed to step 5:
72 divided by 87 is 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 300.0
If we take 0 away from 72, we end up with 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 87

On to step 6:
87 can be fit into 721 8 times, resulting in a remainder of 25.
Record the quotient 8 as the next digit in the result. 
Result so far: 3008.0
Subtract 696 from 721 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
When dividing 250 by 87, we get 2 with a remainder of 76.
The next digit of our result is 2. 
Result so far: 3008.2
The remainder is 76 after subtracting 174 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 8:
87 goes into 760 8 times with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 3008.28
If we take 696 away from 760, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
If we divide 640 by 87, we get 7 and a remainder of 31.
The next digit of our result is 7. 
Result so far: 3008.287
Subtracting 609 from 640 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 10:
87 can be fit into 310 3 times, resulting in a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 3008.2873
Subtract 261 from 310 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 11:
87 can be fit into 490 5 times, resulting in a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 3008.28735
Deduct 435 from 490 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 12:
The number 87 fits into 550 6 times, leaving a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 3008.287356
Subtracting 522 from 550 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 13:
87 can be fit into 280 3 times, resulting in a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 3008.2873563
If we subtract 261 from 280, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 14:
87 can be fit into 190 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 3008.28735632
Subtracting 174 from 190 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 3008.28735632, with a leftover of 1.6e-08.
