We look at the division of 29670 by 86 
Let's see how many times 86 fits into 29670.

Going ahead to step 1:
The number 86 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 86

Step 2:
86 goes into 29 0 times with a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Take the next digit (6) from the dividend and append it to 29, then repeat: 296 / 86

On to step 3:
296 divided by 86 is 3 with a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 258 from 296 leaves us with 38.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 86

Step 4:
86 goes into 387 4 times with a remainder of 43.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we subtract 344 from 387, we get 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 86

Let's proceed to step 5:
When dividing 430 by 86, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 345.0
Deduct 430 from 430 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.

Step 6:
The number 86 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 345.0
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.

Moving on to step 7:
If we divide 0 by 86, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 345.0
Subtract 0 from 0 to 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.

In conclusion, the division gives 345.0 with a balance of 0.0.
