615539 divided by 12 
We want to divide 615539 by 12.

Going ahead to step 1:
If we divide 6 by 12, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 12

Step 2:
12 goes into 61 5 times with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 1 after subtracting 60 from 61.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 12

Advancing to step 3:
The number 12 fits into 15 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we subtract 12 from 15, we get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 12

Let's proceed to step 4:
12 goes into 35 2 times with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 512.0
If we subtract 24 from 35, we get 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 12

Moving on to step 5:
113 divided by 12 is 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 5129.0
Deduct 108 from 113 and we're left with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 12

Let's proceed to step 6:
12 can be fit into 59 4 times, resulting in a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 51294.0
If we take 48 away from 59, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
12 can be fit into 110 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 51294.9
If we subtract 108 from 110, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 12 fits into 20 1 times, leaving a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 51294.91
Deduct 12 from 20 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
80 divided by 12 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 51294.916
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
12 goes into 80 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 51294.9166
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 51294.9166, with a leftover of 8e-05.
