148422 divided by 12 
Let's see how many times 12 fits into 148422.

Moving on to step 1:
When dividing 1 by 12, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 12

Step 2:
12 goes into 14 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 12 from 14 and we're left with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 12

Step 3:
If we divide 28 by 12, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 24 from 28, we get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 12

Step 4:
12 goes into 44 3 times with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 123.0
If we subtract 36 from 44, we get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 12

Going ahead to step 5:
If we divide 82 by 12, we get 6 and a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 1236.0
The remainder is 10 after subtracting 72 from 82.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 12

Let's proceed to step 6:
12 can be fit into 102 8 times, resulting in a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 12368.0
Deduct 96 from 102 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
60 divided by 12 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 12368.5
Deduct 60 from 60 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.

Moving on to step 8:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12368.5
If we take 0 away from 0, we end up 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.

Moving on to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12368.5
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 12368.5 with a remainder of 0.0.
