Let's divide 16408694 by 666
Let's see how many times 666 fits into 16408694.

Going ahead to step 1:
When dividing 1 by 666, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 666

Going ahead to step 2:
666 goes into 16 0 times with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 666

Moving on to step 3:
666 can be fit into 164 0 times, resulting in a remainder of 164.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 164 leaves us with 164.
Fetch the next digit (0) from the dividend, attach it to 164 and continue: 1640 / 666

Step 4:
666 can be fit into 1640 2 times, resulting in a remainder of 308.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1332 from 1640, we get 308.
Fetch the next digit (8) from the dividend, attach it to 308 and continue: 3088 / 666

Let's proceed to step 5:
666 goes into 3088 4 times with a remainder of 424.
The next digit of our result is 4. 
Result so far: 24.0
If we subtract 2664 from 3088, we get 424.
Take the next digit (6) from the dividend and append it to 424, then repeat: 4246 / 666

Step 6:
666 can be fit into 4246 6 times, resulting in a remainder of 250.
Use 6 as the next digit of our solution. 
Result so far: 246.0
If we take 3996 away from 4246, we end up with 250.
Fetch the next digit (9) from the dividend, attach it to 250 and continue: 2509 / 666

Moving on to step 7:
666 goes into 2509 3 times with a remainder of 511.
The number 3 becomes the next digit in our result. 
Result so far: 2463.0
Subtracting 1998 from 2509 leaves us with 511.
Grab the next digit (4) from the dividend, add it to 511, then carry on: 5114 / 666

Going ahead to step 8:
If we divide 5114 by 666, we get 7 and a remainder of 452.
The number 7 becomes the next digit in our result. 
Result so far: 24637.0
Subtracting 4662 from 5114 leaves us with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Going ahead to step 9:
666 can be fit into 4520 6 times, resulting in a remainder of 524.
Write down 6 as next digit of the result. 
Result so far: 24637.6
The remainder is 524 after subtracting 3996 from 4520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Advancing to step 10:
If we divide 5240 by 666, we get 7 and a remainder of 578.
Put 7 as the next digit of the answer. 
Result so far: 24637.67
Subtract 4662 from 5240 to get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Step 11:
The number 666 fits into 5780 8 times, leaving a remainder of 452.
The next digit of our result is 8. 
Result so far: 24637.678
If we subtract 5328 from 5780, we get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Step 12:
If we divide 4520 by 666, we get 6 and a remainder of 524.
The next digit of our result is 6. 
Result so far: 24637.6786
If we subtract 3996 from 4520, we get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Advancing to step 13:
666 goes into 5240 7 times with a remainder of 578.
The next digit of our result is 7. 
Result so far: 24637.67867
Deduct 4662 from 5240 and we're left with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Advancing to step 14:
666 goes into 5780 8 times with a remainder of 452.
The number 8 becomes the next digit in our result. 
Result so far: 24637.678678
Subtract 5328 from 5780 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Let's proceed to step 15:
666 can be fit into 4520 6 times, resulting in a remainder of 524.
Put 6 as the next digit of the answer. 
Result so far: 24637.6786786
If we take 3996 away from 4520, we end up with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Going ahead to step 16:
The number 666 fits into 5240 7 times, leaving a remainder of 578.
Write down 7 as next digit of the result. 
Result so far: 24637.67867867
Subtracting 4662 from 5240 leaves us with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Our division results in 24637.67867867 with a remaining 5.78e-07.
