86140548 divided by 522 
Our goal is to divide 86140548 by 522.

On to step 1:
If we divide 8 by 522, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 522

Going ahead to step 2:
522 can be fit into 86 0 times, resulting in a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Append the next digit (1) from the dividend to 86 and continue with: 861 / 522

Going ahead to step 3:
If we divide 861 by 522, we get 1 and a remainder of 339.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 522 from 861, we get 339.
Take the next digit (4) from the dividend and append it to 339, then repeat: 3394 / 522

Moving on to step 4:
3394 divided by 522 is 6 with a remainder of 262.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 3132 from 3394, we get 262.
Grab the next digit (0) from the dividend, add it to 262, then carry on: 2620 / 522

On to step 5:
If we divide 2620 by 522, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 165.0
Subtract 2610 from 2620 to get 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 522

Going ahead to step 6:
If we divide 105 by 522, we get 0 and a remainder of 105.
Write down 0 as next digit of the result. 
Result so far: 1650.0
The remainder is 105 after subtracting 0 from 105.
Include the next digit (4) from the dividend after 105, then repeat: 1054 / 522

Step 7:
522 goes into 1054 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 16502.0
The remainder is 10 after subtracting 1044 from 1054.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 522

Let's proceed to step 8:
If we divide 108 by 522, we get 0 and a remainder of 108.
The number 0 becomes the next digit in our result. 
Result so far: 165020.0
Deduct 0 from 108 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 9:
522 goes into 1080 2 times with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 165020.2
The remainder is 36 after subtracting 1044 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
If we divide 360 by 522, we get 0 and a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 165020.2
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 11:
If we divide 3600 by 522, we get 6 and a remainder of 468.
The next digit of our result is 6. 
Result so far: 165020.206
Deduct 3132 from 3600 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Going ahead to step 12:
If we divide 4680 by 522, we get 8 and a remainder of 504.
The next digit of our result is 8. 
Result so far: 165020.2068
Subtract 4176 from 4680 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Going ahead to step 13:
522 can be fit into 5040 9 times, resulting in a remainder of 342.
The next digit of our result is 9. 
Result so far: 165020.20689
Subtract 4698 from 5040 to get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Let's proceed to step 14:
3420 divided by 522 is 6 with a remainder of 288.
Record the quotient 6 as the next digit in the result. 
Result so far: 165020.206896
Subtracting 3132 from 3420 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 15:
2880 divided by 522 is 5 with a remainder of 270.
Put 5 as the next digit of the answer. 
Result so far: 165020.2068965
Deduct 2610 from 2880 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 16:
When dividing 2700 by 522, we get 5 with a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 165020.20689655
The remainder is 90 after subtracting 2610 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final result is 165020.20689655 with a remainder of 9e-08.
