We divide 42127657 by 666
Our goal is to divide 42127657 by 666.

Let's proceed to step 1:
The number 666 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 666

Going ahead to step 2:
42 divided by 666 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 666

Moving on to step 3:
If we divide 421 by 666, we get 0 and a remainder of 421.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 421 to get 421.
Bring next digit (2) of the dividend behind the 421 and repeat the process: 4212 / 666

Step 4:
4212 divided by 666 is 6 with a remainder of 216.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 3996 from 4212 to get 216.
Include the next digit (7) from the dividend after 216, then repeat: 2167 / 666

Step 5:
666 can be fit into 2167 3 times, resulting in a remainder of 169.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Deduct 1998 from 2167 and we're left with 169.
Append the next digit (6) from the dividend to 169 and continue with: 1696 / 666

Step 6:
The number 666 fits into 1696 2 times, leaving a remainder of 364.
Use 2 as the next digit of our solution. 
Result so far: 632.0
If we take 1332 away from 1696, we end up with 364.
Bring next digit (5) of the dividend behind the 364 and repeat the process: 3645 / 666

On to step 7:
When dividing 3645 by 666, we get 5 with a remainder of 315.
The next digit of our result is 5. 
Result so far: 6325.0
If we subtract 3330 from 3645, we get 315.
Fetch the next digit (7) from the dividend, attach it to 315 and continue: 3157 / 666

On to step 8:
3157 divided by 666 is 4 with a remainder of 493.
The number 4 becomes the next digit in our result. 
Result so far: 63254.0
The remainder is 493 after subtracting 2664 from 3157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Step 9:
If we divide 4930 by 666, we get 7 and a remainder of 268.
Record the quotient 7 as the next digit in the result. 
Result so far: 63254.7
Deduct 4662 from 4930 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 10:
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: 63254.74
The remainder is 16 after subtracting 2664 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
If we divide 160 by 666, we get 0 and a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 63254.74
Subtract 0 from 160 to 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.

Let's proceed to step 12:
1600 divided by 666 is 2 with a remainder of 268.
Write down 2 as next digit of the result. 
Result so far: 63254.7402
Subtract 1332 from 1600 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 13:
If we divide 2680 by 666, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 63254.74024
The remainder is 16 after subtracting 2664 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
160 divided by 666 is 0 with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 63254.74024
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.

Step 15:
666 can be fit into 1600 2 times, resulting in a remainder of 268.
Put 2 as the next digit of the answer. 
Result so far: 63254.7402402
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 16:
When dividing 2680 by 666, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 63254.74024024
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.

The final outcome is 63254.74024024, with a leftover of 1.6e-08.
