Let's divide 209887 by 86
We're looking to find how many times 86 goes into 209887.

On to step 1:
86 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 86

Let's proceed to step 2:
86 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 86

Going ahead to step 3:
The number 86 fits into 209 2 times, leaving a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 172 from 209 and we're left with 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 86

Step 4:
When dividing 378 by 86, we get 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 24.0
The remainder is 34 after subtracting 344 from 378.
Take the next digit (8) from the dividend and append it to 34, then repeat: 348 / 86

Going ahead to step 5:
348 divided by 86 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 244.0
If we take 344 away from 348, we end up with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 86

Let's proceed to step 6:
86 goes into 47 0 times with a remainder of 47.
Use 0 as the next digit of our solution. 
Result so far: 2440.0
If we subtract 0 from 47, we 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.

Step 7:
If we divide 470 by 86, we get 5 and a remainder of 40.
The next digit of our result is 5. 
Result so far: 2440.5
Subtract 430 from 470 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
The number 86 fits into 400 4 times, leaving a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 2440.54
Subtracting 344 from 400 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
560 divided by 86 is 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 2440.546
If we take 516 away from 560, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
If we divide 440 by 86, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 2440.5465
Subtracting 430 from 440 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
100 divided by 86 is 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 2440.54651
The remainder is 14 after subtracting 86 from 100.
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 12:
When dividing 140 by 86, we get 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 2440.546511
Subtracting 86 from 140 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 2440.546511, and the remainder is 5.4e-06.
