We look at the division of 215645 by 12 
We want to divide 215645 by 12.

Moving on to step 1:
When dividing 2 by 12, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 12

Advancing to step 2:
12 goes into 21 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 12 from 21, we get 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 12

Let's proceed to step 3:
12 can be fit into 95 7 times, resulting in a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 11 after subtracting 84 from 95.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 12

Advancing to step 4:
If we divide 116 by 12, we get 9 and a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 179.0
The remainder is 8 after subtracting 108 from 116.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 12

Going ahead to step 5:
If we divide 84 by 12, we get 7 and a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 1797.0
If we take 84 away from 84, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 12

Let's proceed to step 6:
12 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 17970.0
The remainder is 5 after subtracting 0 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
The number 12 fits into 50 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 17970.4
If we subtract 48 from 50, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
If we divide 20 by 12, we get 1 and a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 17970.41
The remainder is 8 after subtracting 12 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
If we divide 80 by 12, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 17970.416
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
When dividing 80 by 12, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 17970.4166
Deduct 72 from 80 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.

The quotient of the division is 17970.4166, and the remainder is 8e-05.
