347889 ÷ 12 
Let's see how many times 12 fits into 347889.

Moving on to step 1:
When dividing 3 by 12, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 12

On to step 2:
When dividing 34 by 12, we get 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 24 from 34 and we're left with 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 12

Step 3:
12 goes into 107 8 times with a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we take 96 away from 107, we end up with 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 12

On to step 4:
118 divided by 12 is 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 289.0
If we subtract 108 from 118, we get 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 12

Step 5:
If we divide 108 by 12, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 2899.0
Subtract 108 from 108 to get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 12

Let's proceed to step 6:
12 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 28990.0
Deduct 0 from 9 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
If we divide 90 by 12, we get 7 and a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 28990.7
If we take 84 away from 90, we end up 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 8:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 28990.75
If we subtract 60 from 60, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 28990.75
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.

Advancing to step 10:
12 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 28990.75
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.

The final result is 28990.75 with a remainder of 0.0.
