137888 ÷ 12 
Our goal is to divide 137888 by 12.

Step 1:
12 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 12

On to step 2:
13 divided by 12 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 1 after subtracting 12 from 13.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 12

Step 3:
17 divided by 12 is 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 5 after subtracting 12 from 17.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 12

Going ahead to step 4:
12 can be fit into 58 4 times, resulting in a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 114.0
If we take 48 away from 58, we end up with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 12

Advancing to step 5:
12 can be fit into 108 9 times, resulting in a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 1149.0
If we subtract 108 from 108, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 12

Going ahead to step 6:
8 divided by 12 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 11490.0
If we take 0 away from 8, we end up 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.

Step 7:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 11490.6
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
When dividing 80 by 12, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 11490.66
If we take 72 away from 80, we end up 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.

In conclusion, the division gives 11490.66 with a balance of 0.008.
