We divide 66478723 by 666
Let's see how many times 666 fits into 66478723.

Advancing to step 1:
666 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 666

Going ahead to step 2:
666 can be fit into 66 0 times, resulting in a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Append the next digit (4) from the dividend to 66 and continue with: 664 / 666

Moving on to step 3:
666 can be fit into 664 0 times, resulting in a remainder of 664.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 664 leaves us with 664.
Take the next digit (7) from the dividend and append it to 664, then repeat: 6647 / 666

Going ahead to step 4:
If we divide 6647 by 666, we get 9 and a remainder of 653.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 653 after subtracting 5994 from 6647.
Take the next digit (8) from the dividend and append it to 653, then repeat: 6538 / 666

Let's proceed to step 5:
666 goes into 6538 9 times with a remainder of 544.
The next digit of our result is 9. 
Result so far: 99.0
If we subtract 5994 from 6538, we get 544.
Include the next digit (7) from the dividend after 544, then repeat: 5447 / 666

Moving on to step 6:
666 can be fit into 5447 8 times, resulting in a remainder of 119.
Record the quotient 8 as the next digit in the result. 
Result so far: 998.0
Subtracting 5328 from 5447 leaves us with 119.
Bring next digit (2) of the dividend behind the 119 and repeat the process: 1192 / 666

Step 7:
666 goes into 1192 1 times with a remainder of 526.
Write down 1 as next digit of the result. 
Result so far: 9981.0
If we take 666 away from 1192, we end up with 526.
Include the next digit (3) from the dividend after 526, then repeat: 5263 / 666

Going ahead to step 8:
666 can be fit into 5263 7 times, resulting in a remainder of 601.
Put 7 as the next digit of the answer. 
Result so far: 99817.0
Deduct 4662 from 5263 and we're left with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Moving on to step 9:
666 goes into 6010 9 times with a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 99817.9
If we take 5994 away from 6010, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
160 divided by 666 is 0 with a remainder of 160.
The next digit of our result is 0. 
Result so far: 99817.9
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
The number 666 fits into 1600 2 times, leaving a remainder of 268.
Use 2 as the next digit of our solution. 
Result so far: 99817.902
Deduct 1332 from 1600 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 12:
When dividing 2680 by 666, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 99817.9024
If we subtract 2664 from 2680, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
When dividing 160 by 666, we get 0 with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 99817.9024
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 14:
1600 divided by 666 is 2 with a remainder of 268.
Record the quotient 2 as the next digit in the result. 
Result so far: 99817.902402
The remainder is 268 after subtracting 1332 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 15:
When dividing 2680 by 666, we get 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 99817.9024024
Deduct 2664 from 2680 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 16:
If we divide 160 by 666, we get 0 and a remainder of 160.
The next digit of our result is 0. 
Result so far: 99817.9024024
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

After the division, we end up with 99817.9024024 and a remainder of 1.6e-07.
