We look at the division of 595807 by 12 
We're looking to find how many times 12 goes into 595807.

On to step 1:
The number 12 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 12

On to step 2:
If we divide 59 by 12, we get 4 and a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 48 away from 59, we end up with 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 12

Going ahead to step 3:
12 can be fit into 115 9 times, resulting in a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we take 108 away from 115, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 12

Advancing to step 4:
The number 12 fits into 78 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 496.0
If we subtract 72 from 78, we get 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 12

Moving on to step 5:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 4965.0
If we take 60 away from 60, we end up with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 12

On to step 6:
If we divide 7 by 12, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 49650.0
If we subtract 0 from 7, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
If we divide 70 by 12, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 49650.5
Deduct 60 from 70 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 12 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 49650.58
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
The number 12 fits into 40 3 times, leaving a remainder of 4.
The next digit of our result is 3. 
Result so far: 49650.583
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
If we divide 40 by 12, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 49650.5833
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 49650.5833, with a leftover of 4e-05.
