311667 ÷ 87 
Let's see how many times 87 fits into 311667.

On to step 1:
87 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 87

On to step 2:
87 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 87

On to step 3:
The number 87 fits into 311 3 times, leaving a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 261 from 311 to get 50.
Include the next digit (6) from the dividend after 50, then repeat: 506 / 87

Going ahead to step 4:
The number 87 fits into 506 5 times, leaving a remainder of 71.
Write down 5 as next digit of the result. 
Result so far: 35.0
Deduct 435 from 506 and we're left with 71.
Append the next digit (6) from the dividend to 71 and continue with: 716 / 87

Step 5:
87 can be fit into 716 8 times, resulting in a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 358.0
If we take 696 away from 716, we end up with 20.
Include the next digit (7) from the dividend after 20, then repeat: 207 / 87

Going ahead to step 6:
The number 87 fits into 207 2 times, leaving a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 3582.0
If we take 174 away from 207, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
The number 87 fits into 330 3 times, leaving a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 3582.3
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.

Step 8:
690 divided by 87 is 7 with a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 3582.37
If we take 609 away from 690, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 9:
810 divided by 87 is 9 with a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 3582.379
Subtract 783 from 810 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 10:
270 divided by 87 is 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 3582.3793
If we take 261 away from 270, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 11:
When dividing 90 by 87, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 3582.37931
If we subtract 87 from 90, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
If we divide 30 by 87, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 3582.37931
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
87 goes into 300 3 times with a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 3582.3793103
If we take 261 away from 300, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 14:
390 divided by 87 is 4 with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 3582.37931034
The remainder is 42 after subtracting 348 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 3582.37931034, with a leftover of 4.2e-08.
