225800 ÷ 12 
We're looking to find how many times 12 goes into 225800.

Going ahead to step 1:
If we divide 2 by 12, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 12

Going ahead to step 2:
12 goes into 22 1 times with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 10 after subtracting 12 from 22.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 12

Moving on to step 3:
12 can be fit into 105 8 times, resulting in a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 18.0
The remainder is 9 after subtracting 96 from 105.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 12

On to step 4:
12 can be fit into 98 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 188.0
The remainder is 2 after subtracting 96 from 98.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 12

Step 5:
12 goes into 20 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1881.0
Subtract 12 from 20 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 12

Advancing to step 6:
If we divide 80 by 12, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 18816.0
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
When dividing 80 by 12, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 18816.6
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
When dividing 80 by 12, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 18816.66
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 18816.66 with a balance of 0.008.
