61318586 divided by 12 
We're looking to find how many times 12 goes into 61318586.

Step 1:
When dividing 6 by 12, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 12

Let's proceed to step 2:
12 can be fit into 61 5 times, resulting in a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 60 away from 61, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 12

On to step 3:
12 goes into 13 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we take 12 away from 13, we end up with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 12

Moving on to step 4:
If we divide 11 by 12, we get 0 and a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 510.0
Deduct 0 from 11 and we're left with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 12

Going ahead to step 5:
The number 12 fits into 118 9 times, leaving a remainder of 10.
The next digit of our result is 9. 
Result so far: 5109.0
Subtract 108 from 118 to get 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 12

Advancing to step 6:
When dividing 105 by 12, we get 8 with a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 51098.0
Deduct 96 from 105 and we're left with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 12

Moving on to step 7:
12 can be fit into 98 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 510988.0
Subtracting 96 from 98 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 12

Going ahead to step 8:
When dividing 26 by 12, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 5109882.0
The remainder is 2 after subtracting 24 from 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
If we divide 20 by 12, we get 1 and a remainder of 8.
The next digit of our result is 1. 
Result so far: 5109882.1
If we take 12 away from 20, we end up 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.

On to step 10:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 5109882.16
If we take 72 away from 80, we end up 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 11:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 5109882.166
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.

The quotient of the division is 5109882.166, and the remainder is 0.0008.
