We look at the division of 348305 by 86 
We want to divide 348305 by 86.

On to step 1:
When dividing 3 by 86, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 86

Let's proceed to step 2:
If we divide 34 by 86, we get 0 and a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Grab the next digit (8) from the dividend, add it to 34, then carry on: 348 / 86

Going ahead to step 3:
If we divide 348 by 86, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 344 away from 348, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 86

Let's proceed to step 4:
86 goes into 43 0 times with a remainder of 43.
The next digit of our result is 0. 
Result so far: 40.0
Subtract 0 from 43 to get 43.
Take the next digit (0) from the dividend and append it to 43, then repeat: 430 / 86

Step 5:
The number 86 fits into 430 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 405.0
If we subtract 430 from 430, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 86

Going ahead to step 6:
When dividing 5 by 86, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 4050.0
The remainder is 5 after subtracting 0 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
If we divide 50 by 86, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 4050.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
86 can be fit into 500 5 times, resulting in a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 4050.05
If we subtract 430 from 500, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
700 divided by 86 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 4050.058
Subtracting 688 from 700 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
120 divided by 86 is 1 with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 4050.0581
The remainder is 34 after subtracting 86 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 11:
340 divided by 86 is 3 with a remainder of 82.
Write down 3 as next digit of the result. 
Result so far: 4050.05813
Deduct 258 from 340 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 12:
86 can be fit into 820 9 times, resulting in a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 4050.058139
Subtracting 774 from 820 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 13:
If we divide 460 by 86, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 4050.0581395
If we take 430 away from 460, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
If we divide 300 by 86, we get 3 and a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 4050.05813953
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 4050.05813953 with a remainder of 4.2e-08.
