102222 divided by 45 
We want to figure out the number of times 102222 can be divided by 45.

Step 1:
45 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 45

Advancing to step 2:
When dividing 10 by 45, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 45

Step 3:
45 can be fit into 102 2 times, resulting in a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 90 from 102 to get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 45

Advancing to step 4:
If we divide 122 by 45, we get 2 and a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 90 from 122, we get 32.
Bring next digit (2) of the dividend behind the 32 and repeat the process: 322 / 45

Moving on to step 5:
322 divided by 45 is 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 227.0
Subtract 315 from 322 to get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 45

On to step 6:
If we divide 72 by 45, we get 1 and a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 2271.0
Deduct 45 from 72 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
45 goes into 270 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 2271.6
Deduct 270 from 270 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
If we divide 0 by 45, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2271.6
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
The number 45 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2271.6
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 2271.6 with a remainder of 0.0.
