86686109 ÷ 596 
Let's see how many times 596 fits into 86686109.

On to step 1:
The number 596 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 596

Step 2:
When dividing 86 by 596, we get 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Include the next digit (6) from the dividend after 86, then repeat: 866 / 596

Moving on to step 3:
596 can be fit into 866 1 times, resulting in a remainder of 270.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 596 from 866 leaves us with 270.
Bring next digit (8) of the dividend behind the 270 and repeat the process: 2708 / 596

Let's proceed to step 4:
The number 596 fits into 2708 4 times, leaving a remainder of 324.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 324 after subtracting 2384 from 2708.
Take the next digit (6) from the dividend and append it to 324, then repeat: 3246 / 596

Let's proceed to step 5:
The number 596 fits into 3246 5 times, leaving a remainder of 266.
The next digit of our result is 5. 
Result so far: 145.0
Deduct 2980 from 3246 and we're left with 266.
Fetch the next digit (1) from the dividend, attach it to 266 and continue: 2661 / 596

Advancing to step 6:
2661 divided by 596 is 4 with a remainder of 277.
The next digit of our result is 4. 
Result so far: 1454.0
Subtract 2384 from 2661 to get 277.
Take the next digit (0) from the dividend and append it to 277, then repeat: 2770 / 596

Let's proceed to step 7:
If we divide 2770 by 596, we get 4 and a remainder of 386.
Record the quotient 4 as the next digit in the result. 
Result so far: 14544.0
If we take 2384 away from 2770, we end up with 386.
Append the next digit (9) from the dividend to 386 and continue with: 3869 / 596

Going ahead to step 8:
The number 596 fits into 3869 6 times, leaving a remainder of 293.
Use 6 as the next digit of our solution. 
Result so far: 145446.0
Subtracting 3576 from 3869 leaves us with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Going ahead to step 9:
596 goes into 2930 4 times with a remainder of 546.
The next digit of our result is 4. 
Result so far: 145446.4
If we subtract 2384 from 2930, we get 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Step 10:
596 goes into 5460 9 times with a remainder of 96.
Record the quotient 9 as the next digit in the result. 
Result so far: 145446.49
If we subtract 5364 from 5460, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 11:
If we divide 960 by 596, we get 1 and a remainder of 364.
The next digit of our result is 1. 
Result so far: 145446.491
The remainder is 364 after subtracting 596 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Let's proceed to step 12:
3640 divided by 596 is 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 145446.4916
The remainder is 64 after subtracting 3576 from 3640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
The number 596 fits into 640 1 times, leaving a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 145446.49161
Subtract 596 from 640 to 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.

Let's proceed to step 14:
When dividing 440 by 596, we get 0 with a remainder of 440.
Use 0 as the next digit of our solution. 
Result so far: 145446.49161
Subtract 0 from 440 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 15:
4400 divided by 596 is 7 with a remainder of 228.
The number 7 becomes the next digit in our result. 
Result so far: 145446.4916107
If we subtract 4172 from 4400, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

On to step 16:
The number 596 fits into 2280 3 times, leaving a remainder of 492.
Use 3 as the next digit of our solution. 
Result so far: 145446.49161073
Subtract 1788 from 2280 to get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

The final outcome is 145446.49161073, with a leftover of 4.92e-07.
