We look at the division of 21678512 by 180 
We want to divide 21678512 by 180.

Let's proceed to step 1:
When dividing 2 by 180, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 180

Step 2:
If we divide 21 by 180, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 180

Let's proceed to step 3:
180 goes into 216 1 times with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 180 from 216 and we're left with 36.
Bring next digit (7) of the dividend behind the 36 and repeat the process: 367 / 180

On to step 4:
367 divided by 180 is 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 360 from 367, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 180

Let's proceed to step 5:
180 can be fit into 78 0 times, resulting in a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
If we subtract 0 from 78, we get 78.
Take the next digit (5) from the dividend and append it to 78, then repeat: 785 / 180

On to step 6:
180 goes into 785 4 times with a remainder of 65.
The next digit of our result is 4. 
Result so far: 1204.0
The remainder is 65 after subtracting 720 from 785.
Bring next digit (1) of the dividend behind the 65 and repeat the process: 651 / 180

Let's proceed to step 7:
651 divided by 180 is 3 with a remainder of 111.
Write down 3 as next digit of the result. 
Result so far: 12043.0
The remainder is 111 after subtracting 540 from 651.
Fetch the next digit (2) from the dividend, attach it to 111 and continue: 1112 / 180

On to step 8:
180 goes into 1112 6 times with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 120436.0
Subtracting 1080 from 1112 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
320 divided by 180 is 1 with a remainder of 140.
Put 1 as the next digit of the answer. 
Result so far: 120436.1
Subtracting 180 from 320 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
The number 180 fits into 1400 7 times, leaving a remainder of 140.
The next digit of our result is 7. 
Result so far: 120436.17
Subtract 1260 from 1400 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 11:
1400 divided by 180 is 7 with a remainder of 140.
Write down 7 as next digit of the result. 
Result so far: 120436.177
The remainder is 140 after subtracting 1260 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The quotient of the division is 120436.177, and the remainder is 0.014.
