Let's divide 29986 by 86
We're looking to find how many times 86 goes into 29986.

Let's proceed to step 1:
The number 86 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
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

Moving on to step 2:
86 can be fit into 29 0 times, resulting in a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 29 to get 29.
Take the next digit (9) from the dividend and append it to 29, then repeat: 299 / 86

On to step 3:
86 can be fit into 299 3 times, resulting in a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 258 from 299 and we're left with 41.
Take the next digit (8) from the dividend and append it to 41, then repeat: 418 / 86

Advancing to step 4:
When dividing 418 by 86, we get 4 with a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we take 344 away from 418, we end up with 74.
Fetch the next digit (6) from the dividend, attach it to 74 and continue: 746 / 86

Going ahead to step 5:
86 can be fit into 746 8 times, resulting in a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 348.0
Deduct 688 from 746 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 6:
580 divided by 86 is 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 348.6
Deduct 516 from 580 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 7:
The number 86 fits into 640 7 times, leaving a remainder of 38.
The next digit of our result is 7. 
Result so far: 348.67
If we subtract 602 from 640, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
If we divide 380 by 86, we get 4 and a remainder of 36.
The next digit of our result is 4. 
Result so far: 348.674
Deduct 344 from 380 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
When dividing 360 by 86, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 348.6744
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 348.6744, with a leftover of 0.00016.
