We're dividing 21921630 by 180 
We want to divide 21921630 by 180.

Advancing to step 1:
180 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 180

Moving on to step 2:
180 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 180

Going ahead to step 3:
When dividing 219 by 180, we get 1 with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 180 from 219, we get 39.
Bring next digit (2) of the dividend behind the 39 and repeat the process: 392 / 180

Moving on to step 4:
392 divided by 180 is 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 360 from 392 leaves us with 32.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 180

Advancing to step 5:
321 divided by 180 is 1 with a remainder of 141.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
The remainder is 141 after subtracting 180 from 321.
Append the next digit (6) from the dividend to 141 and continue with: 1416 / 180

Advancing to step 6:
1416 divided by 180 is 7 with a remainder of 156.
Write down 7 as next digit of the result. 
Result so far: 1217.0
The remainder is 156 after subtracting 1260 from 1416.
Bring next digit (3) of the dividend behind the 156 and repeat the process: 1563 / 180

Going ahead to step 7:
1563 divided by 180 is 8 with a remainder of 123.
Write down 8 as next digit of the result. 
Result so far: 12178.0
The remainder is 123 after subtracting 1440 from 1563.
Bring next digit (0) of the dividend behind the 123 and repeat the process: 1230 / 180

Let's proceed to step 8:
180 can be fit into 1230 6 times, resulting in a remainder of 150.
Use 6 as the next digit of our solution. 
Result so far: 121786.0
If we subtract 1080 from 1230, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 9:
180 can be fit into 1500 8 times, resulting in a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 121786.8
Subtracting 1440 from 1500 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
If we divide 600 by 180, we get 3 and a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 121786.83
If we take 540 away from 600, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
When dividing 600 by 180, we get 3 with a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 121786.833
Subtracting 540 from 600 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 121786.833, and the remainder is 0.006.
