We look at the division of 221982 by 45 
We want to divide 221982 by 45.

Moving on to step 1:
2 divided by 45 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 45

On to step 2:
22 divided by 45 is 0 with a remainder of 22.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 45

Going ahead to step 3:
45 can be fit into 221 4 times, resulting in a remainder of 41.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 180 away from 221, we end up with 41.
Append the next digit (9) from the dividend to 41 and continue with: 419 / 45

On to step 4:
When dividing 419 by 45, we get 9 with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 49.0
The remainder is 14 after subtracting 405 from 419.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 45

Advancing to step 5:
The number 45 fits into 148 3 times, leaving a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 493.0
If we take 135 away from 148, we end up with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 45

Step 6:
132 divided by 45 is 2 with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 4932.0
The remainder is 42 after subtracting 90 from 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
When dividing 420 by 45, we get 9 with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 4932.9
Subtract 405 from 420 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
45 goes into 150 3 times with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 4932.93
If we subtract 135 from 150, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
The number 45 fits into 150 3 times, leaving a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 4932.933
Subtract 135 from 150 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 4932.933 and a remainder of 0.0015.
