Let's divide 3891629 by 666
Our goal is to divide 3891629 by 666.

Moving on to step 1:
When dividing 3 by 666, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 666

Going ahead to step 2:
When dividing 38 by 666, we get 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Take the next digit (9) from the dividend and append it to 38, then repeat: 389 / 666

Going ahead to step 3:
666 can be fit into 389 0 times, resulting in a remainder of 389.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 389, we end up with 389.
Append the next digit (1) from the dividend to 389 and continue with: 3891 / 666

Advancing to step 4:
When dividing 3891 by 666, we get 5 with a remainder of 561.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 3330 from 3891 and we're left with 561.
Include the next digit (6) from the dividend after 561, then repeat: 5616 / 666

On to step 5:
When dividing 5616 by 666, we get 8 with a remainder of 288.
Write down 8 as next digit of the result. 
Result so far: 58.0
If we take 5328 away from 5616, we end up with 288.
Bring next digit (2) of the dividend behind the 288 and repeat the process: 2882 / 666

Moving on to step 6:
666 goes into 2882 4 times with a remainder of 218.
Write down 4 as next digit of the result. 
Result so far: 584.0
Subtract 2664 from 2882 to get 218.
Append the next digit (9) from the dividend to 218 and continue with: 2189 / 666

Moving on to step 7:
The number 666 fits into 2189 3 times, leaving a remainder of 191.
Write down 3 as next digit of the result. 
Result so far: 5843.0
If we subtract 1998 from 2189, we get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Let's proceed to step 8:
When dividing 1910 by 666, we get 2 with a remainder of 578.
Record the quotient 2 as the next digit in the result. 
Result so far: 5843.2
If we subtract 1332 from 1910, we 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.

On to step 9:
If we divide 5780 by 666, we get 8 and a remainder of 452.
Write down 8 as next digit of the result. 
Result so far: 5843.28
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.

Step 10:
If we divide 4520 by 666, we get 6 and a remainder of 524.
The number 6 becomes the next digit in our result. 
Result so far: 5843.286
Subtracting 3996 from 4520 leaves us 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.

Advancing to step 11:
When dividing 5240 by 666, we get 7 with a remainder of 578.
The next digit of our result is 7. 
Result so far: 5843.2867
If we subtract 4662 from 5240, we 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 12:
If we divide 5780 by 666, we get 8 and a remainder of 452.
Write down 8 as next digit of the result. 
Result so far: 5843.28678
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.

Advancing to step 13:
666 can be fit into 4520 6 times, resulting in a remainder of 524.
The number 6 becomes the next digit in our result. 
Result so far: 5843.286786
Subtracting 3996 from 4520 leaves us 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.

Advancing to step 14:
If we divide 5240 by 666, we get 7 and a remainder of 578.
Use 7 as the next digit of our solution. 
Result so far: 5843.2867867
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.

Going ahead to step 15:
666 can be fit into 5780 8 times, resulting in a remainder of 452.
Record the quotient 8 as the next digit in the result. 
Result so far: 5843.28678678
Subtracting 5328 from 5780 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.

In conclusion, the division gives 5843.28678678 with a balance of 4.52e-07.
