Let's divide 311207 by 87
Our goal is to divide 311207 by 87.

Advancing to step 1:
87 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 87

On to step 2:
When dividing 31 by 87, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 87

Step 3:
87 goes into 311 3 times with a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 261 from 311 to get 50.
Append the next digit (2) from the dividend to 50 and continue with: 502 / 87

Moving on to step 4:
The number 87 fits into 502 5 times, leaving a remainder of 67.
Write down 5 as next digit of the result. 
Result so far: 35.0
Deduct 435 from 502 and we're left with 67.
Include the next digit (0) from the dividend after 67, then repeat: 670 / 87

On to step 5:
87 goes into 670 7 times with a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 357.0
If we take 609 away from 670, we end up with 61.
Grab the next digit (7) from the dividend, add it to 61, then carry on: 617 / 87

On to step 6:
617 divided by 87 is 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 3577.0
Deduct 609 from 617 and we're left 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.

Step 7:
87 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 3577.0
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.

Step 8:
If we divide 800 by 87, we get 9 and a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 3577.09
Deduct 783 from 800 and we're left 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.

Moving on to step 9:
170 divided by 87 is 1 with a remainder of 83.
The number 1 becomes the next digit in our result. 
Result so far: 3577.091
Subtracting 87 from 170 leaves us 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.

On to step 10:
830 divided by 87 is 9 with a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 3577.0919
Deduct 783 from 830 and we're left 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.

Advancing to step 11:
87 goes into 470 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 3577.09195
If we take 435 away from 470, we end up 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.

On to step 12:
350 divided by 87 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 3577.091954
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.

On to step 13:
20 divided by 87 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 3577.091954
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
The number 87 fits into 200 2 times, leaving a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 3577.09195402
If we take 174 away from 200, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 3577.09195402 with a remainder of 2.6e-08.
