Let's divide 344557 by 86
Our goal is to divide 344557 by 86.

Going ahead 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
Subtracting 0 from 3 leaves us with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 86

Going ahead to step 2:
86 can be fit into 34 0 times, resulting in a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 86

Going ahead to step 3:
If we divide 344 by 86, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 344 from 344 to get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 86

Let's proceed to step 4:
When dividing 5 by 86, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 40.0
Subtract 0 from 5 to get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 86

Advancing to step 5:
55 divided by 86 is 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 400.0
Subtracting 0 from 55 leaves us with 55.
Grab the next digit (7) from the dividend, add it to 55, then carry on: 557 / 86

Let's proceed to step 6:
When dividing 557 by 86, we get 6 with a remainder of 41.
Put 6 as the next digit of the answer. 
Result so far: 4006.0
The remainder is 41 after subtracting 516 from 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
410 divided by 86 is 4 with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 4006.4
If we subtract 344 from 410, 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.

Moving on to step 8:
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: 4006.47
Deduct 602 from 660 and we're left 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.

Going ahead to step 9:
86 can be fit into 580 6 times, resulting in a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 4006.476
Subtract 516 from 580 to 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.

Step 10:
If we divide 640 by 86, we get 7 and a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 4006.4767
Subtracting 602 from 640 leaves us 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.

Advancing to step 11:
86 can be fit into 380 4 times, resulting in a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 4006.47674
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.

Going ahead to step 12:
360 divided by 86 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 4006.476744
Subtract 344 from 360 to 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 4006.476744 and a remainder of 1.6e-06.
