349054 divided by 86 
We want to divide 349054 by 86.

Moving on to step 1:
If we divide 3 by 86, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 86

Going ahead to step 2:
86 can be fit into 34 0 times, resulting in a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Take the next digit (9) from the dividend and append it to 34, then repeat: 349 / 86

Going ahead to step 3:
349 divided by 86 is 4 with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 344 from 349 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 86

On to step 4:
86 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we take 0 away from 50, we end up with 50.
Append the next digit (5) from the dividend to 50 and continue with: 505 / 86

Step 5:
86 can be fit into 505 5 times, resulting in a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 405.0
Deduct 430 from 505 and we're left with 75.
Fetch the next digit (4) from the dividend, attach it to 75 and continue: 754 / 86

Going ahead to step 6:
86 can be fit into 754 8 times, resulting in a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 4058.0
Subtracting 688 from 754 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 7:
When dividing 660 by 86, we get 7 with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 4058.7
Subtracting 602 from 660 leaves us 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.

On to step 8:
86 goes into 580 6 times with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 4058.76
If we subtract 516 from 580, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
If we divide 640 by 86, we get 7 and a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 4058.767
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 10:
86 can be fit into 380 4 times, resulting in a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 4058.7674
The remainder is 36 after subtracting 344 from 380.
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 11:
If we divide 360 by 86, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 4058.76744
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 4058.76744, with a leftover of 1.6e-05.
