Let's divide 8005664 by 66
We want to figure out the number of times 8005664 can be divided by 66.

On to step 1:
66 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 66

Going ahead to step 2:
80 divided by 66 is 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 66 from 80, we get 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 66

On to step 3:
When dividing 140 by 66, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 132 from 140 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 66

Let's proceed to step 4:
When dividing 85 by 66, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 121.0
Deduct 66 from 85 and we're left with 19.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 66

Advancing to step 5:
66 can be fit into 196 2 times, resulting in a remainder of 64.
The next digit of our result is 2. 
Result so far: 1212.0
Subtracting 132 from 196 leaves us with 64.
Grab the next digit (6) from the dividend, add it to 64, then carry on: 646 / 66

Moving on to step 6:
66 can be fit into 646 9 times, resulting in a remainder of 52.
Put 9 as the next digit of the answer. 
Result so far: 12129.0
Deduct 594 from 646 and we're left with 52.
Append the next digit (4) from the dividend to 52 and continue with: 524 / 66

Let's proceed to step 7:
66 goes into 524 7 times with a remainder of 62.
Write down 7 as next digit of the result. 
Result so far: 121297.0
If we subtract 462 from 524, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 8:
620 divided by 66 is 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 121297.9
Deduct 594 from 620 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
66 can be fit into 260 3 times, resulting in a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 121297.93
Subtracting 198 from 260 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
620 divided by 66 is 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 121297.939
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 11:
260 divided by 66 is 3 with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 121297.9393
Subtracting 198 from 260 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 12:
When dividing 620 by 66, we get 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 121297.93939
Deduct 594 from 620 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
260 divided by 66 is 3 with a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 121297.939393
If we take 198 away from 260, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 14:
66 goes into 620 9 times with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 121297.9393939
Subtract 594 from 620 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 15:
When dividing 260 by 66, we get 3 with a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 121297.93939393
If we subtract 198 from 260, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Our division results in 121297.93939393 with a remaining 6.2e-08.
