We divide 81099930 by 66
We're looking to find how many times 66 goes into 81099930.

Step 1:
66 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 66

Let's proceed to step 2:
When dividing 81 by 66, we get 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 66 from 81 leaves us with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 66

Going ahead to step 3:
66 can be fit into 150 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 132 from 150 to get 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 66

Let's proceed to step 4:
If we divide 189 by 66, we get 2 and a remainder of 57.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
Subtract 132 from 189 to get 57.
Take the next digit (9) from the dividend and append it to 57, then repeat: 579 / 66

Advancing to step 5:
The number 66 fits into 579 8 times, leaving a remainder of 51.
Put 8 as the next digit of the answer. 
Result so far: 1228.0
The remainder is 51 after subtracting 528 from 579.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 66

Moving on to step 6:
If we divide 519 by 66, we get 7 and a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 12287.0
Deduct 462 from 519 and we're left with 57.
Take the next digit (3) from the dividend and append it to 57, then repeat: 573 / 66

On to step 7:
66 goes into 573 8 times with a remainder of 45.
Put 8 as the next digit of the answer. 
Result so far: 122878.0
Subtracting 528 from 573 leaves us with 45.
Fetch the next digit (0) from the dividend, attach it to 45 and continue: 450 / 66

Going ahead to step 8:
When dividing 450 by 66, we get 6 with a remainder of 54.
Write down 6 as next digit of the result. 
Result so far: 1228786.0
If we subtract 396 from 450, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 9:
When dividing 540 by 66, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 1228786.8
Subtract 528 from 540 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
If we divide 120 by 66, we get 1 and a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 1228786.81
Subtracting 66 from 120 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 11:
66 goes into 540 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 1228786.818
The remainder is 12 after subtracting 528 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
The number 66 fits into 120 1 times, leaving a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 1228786.8181
The remainder is 54 after subtracting 66 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 13:
If we divide 540 by 66, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 1228786.81818
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
66 goes into 120 1 times with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 1228786.818181
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 15:
66 can be fit into 540 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 1228786.8181818
Subtract 528 from 540 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 16:
66 can be fit into 120 1 times, resulting in a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 1228786.81818181
If we take 66 away from 120, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 1228786.81818181 and a remainder of 5.4e-08.
