521802 ÷ 86 
We want to divide 521802 by 86.

Going ahead to step 1:
If we divide 5 by 86, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 86

Let's proceed to step 2:
52 divided by 86 is 0 with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Take the next digit (1) from the dividend and append it to 52, then repeat: 521 / 86

Let's proceed to step 3:
The number 86 fits into 521 6 times, leaving a remainder of 5.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 516 from 521, we get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 86

On to step 4:
When dividing 58 by 86, we get 0 with a remainder of 58.
The next digit of our result is 0. 
Result so far: 60.0
Subtracting 0 from 58 leaves us with 58.
Fetch the next digit (0) from the dividend, attach it to 58 and continue: 580 / 86

On to step 5:
86 can be fit into 580 6 times, resulting in a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 606.0
Subtracting 516 from 580 leaves us with 64.
Take the next digit (2) from the dividend and append it to 64, then repeat: 642 / 86

Step 6:
If we divide 642 by 86, we get 7 and a remainder of 40.
The next digit of our result is 7. 
Result so far: 6067.0
The remainder is 40 after subtracting 602 from 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
86 can be fit into 400 4 times, resulting in a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 6067.4
If we subtract 344 from 400, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 8:
If we divide 560 by 86, we get 6 and a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 6067.46
If we subtract 516 from 560, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
If we divide 440 by 86, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 6067.465
Subtract 430 from 440 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
If we divide 100 by 86, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 6067.4651
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
86 can be fit into 140 1 times, resulting in a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 6067.46511
The remainder is 54 after subtracting 86 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 6067.46511 with a remainder of 5.4e-05.
