We're dividing 59640178 by 859 
We want to figure out the number of times 59640178 can be divided by 859.

On to step 1:
859 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 859

On to step 2:
859 can be fit into 59 0 times, resulting in a remainder of 59.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 59 after subtracting 0 from 59.
Take the next digit (6) from the dividend and append it to 59, then repeat: 596 / 859

Let's proceed to step 3:
596 divided by 859 is 0 with a remainder of 596.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 596 to get 596.
Fetch the next digit (4) from the dividend, attach it to 596 and continue: 5964 / 859

Let's proceed to step 4:
If we divide 5964 by 859, we get 6 and a remainder of 810.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 810 after subtracting 5154 from 5964.
Include the next digit (0) from the dividend after 810, then repeat: 8100 / 859

Advancing to step 5:
859 can be fit into 8100 9 times, resulting in a remainder of 369.
Put 9 as the next digit of the answer. 
Result so far: 69.0
Subtract 7731 from 8100 to get 369.
Include the next digit (1) from the dividend after 369, then repeat: 3691 / 859

Step 6:
3691 divided by 859 is 4 with a remainder of 255.
Use 4 as the next digit of our solution. 
Result so far: 694.0
Subtracting 3436 from 3691 leaves us with 255.
Take the next digit (7) from the dividend and append it to 255, then repeat: 2557 / 859

Let's proceed to step 7:
2557 divided by 859 is 2 with a remainder of 839.
Record the quotient 2 as the next digit in the result. 
Result so far: 6942.0
Subtracting 1718 from 2557 leaves us with 839.
Fetch the next digit (8) from the dividend, attach it to 839 and continue: 8398 / 859

Going ahead to step 8:
When dividing 8398 by 859, we get 9 with a remainder of 667.
Write down 9 as next digit of the result. 
Result so far: 69429.0
The remainder is 667 after subtracting 7731 from 8398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

Moving on to step 9:
The number 859 fits into 6670 7 times, leaving a remainder of 657.
Put 7 as the next digit of the answer. 
Result so far: 69429.7
Deduct 6013 from 6670 and we're left with 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

On to step 10:
859 can be fit into 6570 7 times, resulting in a remainder of 557.
Write down 7 as next digit of the result. 
Result so far: 69429.77
The remainder is 557 after subtracting 6013 from 6570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

The final outcome is 69429.77, with a leftover of 0.557.
