We're dividing 59085869 by 864 
Let's see how many times 864 fits into 59085869.

Advancing to step 1:
When dividing 5 by 864, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 864

Step 2:
59 divided by 864 is 0 with a remainder of 59.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 59 and we're left with 59.
Append the next digit (0) from the dividend to 59 and continue with: 590 / 864

Going ahead to step 3:
If we divide 590 by 864, we get 0 and a remainder of 590.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 590 to get 590.
Append the next digit (8) from the dividend to 590 and continue with: 5908 / 864

Step 4:
864 can be fit into 5908 6 times, resulting in a remainder of 724.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 5184 from 5908 to get 724.
Include the next digit (5) from the dividend after 724, then repeat: 7245 / 864

Advancing to step 5:
864 goes into 7245 8 times with a remainder of 333.
Put 8 as the next digit of the answer. 
Result so far: 68.0
If we subtract 6912 from 7245, we get 333.
Include the next digit (8) from the dividend after 333, then repeat: 3338 / 864

On to step 6:
864 goes into 3338 3 times with a remainder of 746.
Use 3 as the next digit of our solution. 
Result so far: 683.0
If we take 2592 away from 3338, we end up with 746.
Grab the next digit (6) from the dividend, add it to 746, then carry on: 7466 / 864

On to step 7:
If we divide 7466 by 864, we get 8 and a remainder of 554.
The next digit of our result is 8. 
Result so far: 6838.0
Subtracting 6912 from 7466 leaves us with 554.
Take the next digit (9) from the dividend and append it to 554, then repeat: 5549 / 864

Moving on to step 8:
If we divide 5549 by 864, we get 6 and a remainder of 365.
The number 6 becomes the next digit in our result. 
Result so far: 68386.0
If we subtract 5184 from 5549, we get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

On to step 9:
864 can be fit into 3650 4 times, resulting in a remainder of 194.
Write down 4 as next digit of the result. 
Result so far: 68386.4
The remainder is 194 after subtracting 3456 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 10:
864 can be fit into 1940 2 times, resulting in a remainder of 212.
Use 2 as the next digit of our solution. 
Result so far: 68386.42
Subtracting 1728 from 1940 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 11:
The number 864 fits into 2120 2 times, leaving a remainder of 392.
Put 2 as the next digit of the answer. 
Result so far: 68386.422
Subtract 1728 from 2120 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

The final outcome is 68386.422, with a leftover of 0.0392.
