We look at the division of 42428675 by 666 
Let's see how many times 666 fits into 42428675.

Let's proceed to step 1:
The number 666 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 666

Advancing to step 2:
When dividing 42 by 666, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 666

Moving on to step 3:
666 can be fit into 424 0 times, resulting in a remainder of 424.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 424 to get 424.
Append the next digit (2) from the dividend to 424 and continue with: 4242 / 666

Moving on to step 4:
666 can be fit into 4242 6 times, resulting in a remainder of 246.
The next digit of our result is 6. 
Result so far: 6.0
If we take 3996 away from 4242, we end up with 246.
Grab the next digit (8) from the dividend, add it to 246, then carry on: 2468 / 666

Let's proceed to step 5:
2468 divided by 666 is 3 with a remainder of 470.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Deduct 1998 from 2468 and we're left with 470.
Grab the next digit (6) from the dividend, add it to 470, then carry on: 4706 / 666

On to step 6:
The number 666 fits into 4706 7 times, leaving a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 637.0
If we take 4662 away from 4706, we end up with 44.
Include the next digit (7) from the dividend after 44, then repeat: 447 / 666

Going ahead to step 7:
666 can be fit into 447 0 times, resulting in a remainder of 447.
The number 0 becomes the next digit in our result. 
Result so far: 6370.0
If we subtract 0 from 447, we get 447.
Append the next digit (5) from the dividend to 447 and continue with: 4475 / 666

Going ahead to step 8:
When dividing 4475 by 666, we get 6 with a remainder of 479.
Record the quotient 6 as the next digit in the result. 
Result so far: 63706.0
Subtracting 3996 from 4475 leaves us with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

On to step 9:
666 can be fit into 4790 7 times, resulting in a remainder of 128.
The next digit of our result is 7. 
Result so far: 63706.7
If we take 4662 away from 4790, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 10:
1280 divided by 666 is 1 with a remainder of 614.
The next digit of our result is 1. 
Result so far: 63706.71
Subtracting 666 from 1280 leaves us with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Step 11:
When dividing 6140 by 666, we get 9 with a remainder of 146.
Record the quotient 9 as the next digit in the result. 
Result so far: 63706.719
Deduct 5994 from 6140 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 12:
666 can be fit into 1460 2 times, resulting in a remainder of 128.
Record the quotient 2 as the next digit in the result. 
Result so far: 63706.7192
Subtract 1332 from 1460 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 13:
666 can be fit into 1280 1 times, resulting in a remainder of 614.
The number 1 becomes the next digit in our result. 
Result so far: 63706.71921
The remainder is 614 after subtracting 666 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Step 14:
666 can be fit into 6140 9 times, resulting in a remainder of 146.
Put 9 as the next digit of the answer. 
Result so far: 63706.719219
Subtracting 5994 from 6140 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 15:
666 can be fit into 1460 2 times, resulting in a remainder of 128.
Record the quotient 2 as the next digit in the result. 
Result so far: 63706.7192192
If we take 1332 away from 1460, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 16:
If we divide 1280 by 666, we get 1 and a remainder of 614.
The next digit of our result is 1. 
Result so far: 63706.71921921
Subtracting 666 from 1280 leaves us with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

The final outcome is 63706.71921921, with a leftover of 6.14e-07.
