395375 ÷ 86 
We want to figure out the number of times 395375 can be divided 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
Deduct 0 from 3 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 86

Going ahead to step 2:
When dividing 39 by 86, we get 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 86

Going ahead to step 3:
If we divide 395 by 86, we get 4 and a remainder of 51.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 344 away from 395, we end up with 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 86

Let's proceed to step 4:
If we divide 513 by 86, we get 5 and a remainder of 83.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we take 430 away from 513, we end up with 83.
Fetch the next digit (7) from the dividend, attach it to 83 and continue: 837 / 86

Moving on to step 5:
The number 86 fits into 837 9 times, leaving a remainder of 63.
The next digit of our result is 9. 
Result so far: 459.0
Deduct 774 from 837 and we're left with 63.
Append the next digit (5) from the dividend to 63 and continue with: 635 / 86

Going ahead to step 6:
86 goes into 635 7 times with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 4597.0
Subtract 602 from 635 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 7:
86 goes into 330 3 times with a remainder of 72.
Write down 3 as next digit of the result. 
Result so far: 4597.3
If we take 258 away from 330, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 8:
86 can be fit into 720 8 times, resulting in a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 4597.38
The remainder is 32 after subtracting 688 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
If we divide 320 by 86, we get 3 and a remainder of 62.
The next digit of our result is 3. 
Result so far: 4597.383
Subtracting 258 from 320 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
86 goes into 620 7 times with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 4597.3837
The remainder is 18 after subtracting 602 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
86 can be fit into 180 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 4597.38372
Deduct 172 from 180 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
If we divide 80 by 86, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 4597.38372
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
86 can be fit into 800 9 times, resulting in a remainder of 26.
The next digit of our result is 9. 
Result so far: 4597.3837209
Subtract 774 from 800 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
The number 86 fits into 260 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 4597.38372093
Subtracting 258 from 260 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 4597.38372093, with a leftover of 2e-09.
