349986 divided by 86 
We want to figure out the number of times 349986 can be divided by 86.

Advancing to step 1:
3 divided by 86 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 86

Moving on to step 2:
86 can be fit into 34 0 times, resulting in a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Grab the next digit (9) from the dividend, add it to 34, then carry on: 349 / 86

Let's proceed to step 3:
86 goes into 349 4 times with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 344 from 349 to get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 86

Going ahead to step 4:
86 can be fit into 59 0 times, resulting in a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 40.0
The remainder is 59 after subtracting 0 from 59.
Bring next digit (8) of the dividend behind the 59 and repeat the process: 598 / 86

Let's proceed to step 5:
598 divided by 86 is 6 with a remainder of 82.
The next digit of our result is 6. 
Result so far: 406.0
If we take 516 away from 598, we end up with 82.
Take the next digit (6) from the dividend and append it to 82, then repeat: 826 / 86

Let's proceed to step 6:
86 goes into 826 9 times with a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 4069.0
If we take 774 away from 826, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 7:
When dividing 520 by 86, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 4069.6
If we subtract 516 from 520, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
When dividing 40 by 86, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 4069.6
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
When dividing 400 by 86, we get 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 4069.604
Subtract 344 from 400 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
When dividing 560 by 86, we get 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 4069.6046
The remainder is 44 after subtracting 516 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 11:
If we divide 440 by 86, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 4069.60465
Subtract 430 from 440 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
100 divided by 86 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 4069.604651
Deduct 86 from 100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
The number 86 fits into 140 1 times, leaving a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 4069.6046511
If we take 86 away from 140, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

In conclusion, the division gives 4069.6046511 with a balance of 5.4e-07.
