356519 divided by 86 
Let's see how many times 86 fits into 356519.

Going ahead to step 1:
If we divide 3 by 86, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 86

Moving on to step 2:
When dividing 35 by 86, we get 0 with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Grab the next digit (6) from the dividend, add it to 35, then carry on: 356 / 86

Let's proceed to step 3:
The number 86 fits into 356 4 times, leaving a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 344 from 356 and we're left with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 86

Moving on to step 4:
125 divided by 86 is 1 with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 41.0
Deduct 86 from 125 and we're left with 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 86

Moving on to step 5:
The number 86 fits into 391 4 times, leaving a remainder of 47.
The number 4 becomes the next digit in our result. 
Result so far: 414.0
The remainder is 47 after subtracting 344 from 391.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 86

Let's proceed to step 6:
When dividing 479 by 86, we get 5 with a remainder of 49.
Use 5 as the next digit of our solution. 
Result so far: 4145.0
Subtracting 430 from 479 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
The number 86 fits into 490 5 times, leaving a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 4145.5
If we take 430 away from 490, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
86 can be fit into 600 6 times, resulting in a remainder of 84.
The next digit of our result is 6. 
Result so far: 4145.56
The remainder is 84 after subtracting 516 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 9:
86 can be fit into 840 9 times, resulting in a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 4145.569
If we subtract 774 from 840, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 10:
The number 86 fits into 660 7 times, leaving a remainder of 58.
The next digit of our result is 7. 
Result so far: 4145.5697
If we take 602 away from 660, we end up 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.

Step 11:
If we divide 580 by 86, we get 6 and a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 4145.56976
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.

Moving on to step 12:
86 can be fit into 640 7 times, resulting in a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 4145.569767
If we take 602 away from 640, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 13:
380 divided by 86 is 4 with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 4145.5697674
Subtracting 344 from 380 leaves us 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.

On to step 14:
If we divide 360 by 86, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 4145.56976744
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 4145.56976744 and a remainder of 1.6e-08.
