We look at the division of 209628 by 86 
Let's see how many times 86 fits into 209628.

Step 1:
86 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 86

Moving on to step 2:
When dividing 20 by 86, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 86

Advancing to step 3:
86 goes into 209 2 times with a remainder of 37.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 172 away from 209, we end up with 37.
Bring next digit (6) of the dividend behind the 37 and repeat the process: 376 / 86

Advancing to step 4:
86 goes into 376 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Subtract 344 from 376 to get 32.
Fetch the next digit (2) from the dividend, attach it to 32 and continue: 322 / 86

Let's proceed to step 5:
The number 86 fits into 322 3 times, leaving a remainder of 64.
Record the quotient 3 as the next digit in the result. 
Result so far: 243.0
If we take 258 away from 322, we end up with 64.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 86

Step 6:
86 can be fit into 648 7 times, resulting in a remainder of 46.
Use 7 as the next digit of our solution. 
Result so far: 2437.0
The remainder is 46 after subtracting 602 from 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 7:
If we divide 460 by 86, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 2437.5
The remainder is 30 after subtracting 430 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
The number 86 fits into 300 3 times, leaving a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 2437.53
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
420 divided by 86 is 4 with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 2437.534
Subtracting 344 from 420 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
The number 86 fits into 760 8 times, leaving a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 2437.5348
Deduct 688 from 760 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 11:
720 divided by 86 is 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 2437.53488
The remainder is 32 after subtracting 688 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 2437.53488, with a leftover of 3.2e-05.
