21033620 divided by 180 
We're looking to find how many times 180 goes into 21033620.

Going ahead to step 1:
180 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 180

Going ahead to step 2:
180 goes into 21 0 times with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 180

Advancing to step 3:
180 can be fit into 210 1 times, resulting in a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 180 away from 210, we end up with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 180

On to step 4:
The number 180 fits into 303 1 times, leaving a remainder of 123.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 180 from 303 leaves us with 123.
Include the next digit (3) from the dividend after 123, then repeat: 1233 / 180

Moving on to step 5:
180 can be fit into 1233 6 times, resulting in a remainder of 153.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
If we subtract 1080 from 1233, we get 153.
Bring next digit (6) of the dividend behind the 153 and repeat the process: 1536 / 180

Advancing to step 6:
The number 180 fits into 1536 8 times, leaving a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 1168.0
The remainder is 96 after subtracting 1440 from 1536.
Append the next digit (2) from the dividend to 96 and continue with: 962 / 180

Let's proceed to step 7:
180 can be fit into 962 5 times, resulting in a remainder of 62.
The next digit of our result is 5. 
Result so far: 11685.0
If we take 900 away from 962, we end up with 62.
Include the next digit (0) from the dividend after 62, then repeat: 620 / 180

Step 8:
620 divided by 180 is 3 with a remainder of 80.
Record the quotient 3 as the next digit in the result. 
Result so far: 116853.0
If we take 540 away from 620, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 9:
180 can be fit into 800 4 times, resulting in a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 116853.4
Deduct 720 from 800 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
180 can be fit into 800 4 times, resulting in a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 116853.44
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 116853.44 and a remainder of 0.08.
