We divide 66889668 by 816
We're looking to find how many times 816 goes into 66889668.

Going ahead to step 1:
816 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 816

Moving on to step 2:
The number 816 fits into 66 0 times, leaving a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Include the next digit (8) from the dividend after 66, then repeat: 668 / 816

Going ahead to step 3:
668 divided by 816 is 0 with a remainder of 668.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 668 to get 668.
Fetch the next digit (8) from the dividend, attach it to 668 and continue: 6688 / 816

Going ahead to step 4:
If we divide 6688 by 816, we get 8 and a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 160 after subtracting 6528 from 6688.
Grab the next digit (9) from the dividend, add it to 160, then carry on: 1609 / 816

Let's proceed to step 5:
The number 816 fits into 1609 1 times, leaving a remainder of 793.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
Deduct 816 from 1609 and we're left with 793.
Bring next digit (6) of the dividend behind the 793 and repeat the process: 7936 / 816

On to step 6:
If we divide 7936 by 816, we get 9 and a remainder of 592.
The number 9 becomes the next digit in our result. 
Result so far: 819.0
Subtract 7344 from 7936 to get 592.
Bring next digit (6) of the dividend behind the 592 and repeat the process: 5926 / 816

Step 7:
The number 816 fits into 5926 7 times, leaving a remainder of 214.
Record the quotient 7 as the next digit in the result. 
Result so far: 8197.0
Subtract 5712 from 5926 to get 214.
Include the next digit (8) from the dividend after 214, then repeat: 2148 / 816

On to step 8:
2148 divided by 816 is 2 with a remainder of 516.
The number 2 becomes the next digit in our result. 
Result so far: 81972.0
The remainder is 516 after subtracting 1632 from 2148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 9:
The number 816 fits into 5160 6 times, leaving a remainder of 264.
The next digit of our result is 6. 
Result so far: 81972.6
The remainder is 264 after subtracting 4896 from 5160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 10:
2640 divided by 816 is 3 with a remainder of 192.
The next digit of our result is 3. 
Result so far: 81972.63
If we take 2448 away from 2640, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 11:
If we divide 1920 by 816, we get 2 and a remainder of 288.
Put 2 as the next digit of the answer. 
Result so far: 81972.632
If we subtract 1632 from 1920, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 12:
When dividing 2880 by 816, we get 3 with a remainder of 432.
Write down 3 as next digit of the result. 
Result so far: 81972.6323
If we subtract 2448 from 2880, we get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Going ahead to step 13:
When dividing 4320 by 816, we get 5 with a remainder of 240.
The number 5 becomes the next digit in our result. 
Result so far: 81972.63235
Deduct 4080 from 4320 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 14:
If we divide 2400 by 816, we get 2 and a remainder of 768.
Use 2 as the next digit of our solution. 
Result so far: 81972.632352
Subtract 1632 from 2400 to get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Let's proceed to step 15:
If we divide 7680 by 816, we get 9 and a remainder of 336.
The number 9 becomes the next digit in our result. 
Result so far: 81972.6323529
Deduct 7344 from 7680 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 16:
When dividing 3360 by 816, we get 4 with a remainder of 96.
Record the quotient 4 as the next digit in the result. 
Result so far: 81972.63235294
Deduct 3264 from 3360 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

After the division, we end up with 81972.63235294 and a remainder of 9.6e-08.
