76186606 ÷ 12 
We want to divide 76186606 by 12.

On to step 1:
12 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 12

Moving on to step 2:
If we divide 76 by 12, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 72 from 76, we get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 12

Advancing to step 3:
41 divided by 12 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 63.0
If we take 36 away from 41, we end up with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 12

On to step 4:
When dividing 58 by 12, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 634.0
Deduct 48 from 58 and we're left with 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 12

Moving on to step 5:
The number 12 fits into 106 8 times, leaving a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 6348.0
Subtracting 96 from 106 leaves us with 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 12

Going ahead to step 6:
If we divide 106 by 12, we get 8 and a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 63488.0
Deduct 96 from 106 and we're left with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 12

On to step 7:
The number 12 fits into 100 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 634888.0
The remainder is 4 after subtracting 96 from 100.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 12

Step 8:
12 can be fit into 46 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 6348883.0
Deduct 36 from 46 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.

Let's proceed to step 9:
12 goes into 100 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 6348883.8
Subtract 96 from 100 to 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.

Let's proceed to step 10:
40 divided by 12 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 6348883.83
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 6348883.833
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.

Our division results in 6348883.833 with a remaining 0.0004.
