3834901 ÷ 666 
Let's see how many times 666 fits into 3834901.

Moving on to step 1:
If we divide 3 by 666, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 666

Moving on to step 2:
666 can be fit into 38 0 times, resulting in a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Grab the next digit (3) from the dividend, add it to 38, then carry on: 383 / 666

Going ahead to step 3:
When dividing 383 by 666, we get 0 with a remainder of 383.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 383, we get 383.
Fetch the next digit (4) from the dividend, attach it to 383 and continue: 3834 / 666

Going ahead to step 4:
666 can be fit into 3834 5 times, resulting in a remainder of 504.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 3330 away from 3834, we end up with 504.
Take the next digit (9) from the dividend and append it to 504, then repeat: 5049 / 666

On to step 5:
When dividing 5049 by 666, we get 7 with a remainder of 387.
The next digit of our result is 7. 
Result so far: 57.0
Deduct 4662 from 5049 and we're left with 387.
Include the next digit (0) from the dividend after 387, then repeat: 3870 / 666

Step 6:
If we divide 3870 by 666, we get 5 and a remainder of 540.
Write down 5 as next digit of the result. 
Result so far: 575.0
Deduct 3330 from 3870 and we're left with 540.
Bring next digit (1) of the dividend behind the 540 and repeat the process: 5401 / 666

Step 7:
666 can be fit into 5401 8 times, resulting in a remainder of 73.
Use 8 as the next digit of our solution. 
Result so far: 5758.0
Deduct 5328 from 5401 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 8:
When dividing 730 by 666, we get 1 with a remainder of 64.
The number 1 becomes the next digit in our result. 
Result so far: 5758.1
Deduct 666 from 730 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
If we divide 640 by 666, we get 0 and a remainder of 640.
The number 0 becomes the next digit in our result. 
Result so far: 5758.1
Deduct 0 from 640 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 10:
6400 divided by 666 is 9 with a remainder of 406.
The next digit of our result is 9. 
Result so far: 5758.109
If we take 5994 away from 6400, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Let's proceed to step 11:
The number 666 fits into 4060 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 5758.1096
The remainder is 64 after subtracting 3996 from 4060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
The number 666 fits into 640 0 times, leaving a remainder of 640.
Write down 0 as next digit of the result. 
Result so far: 5758.1096
If we subtract 0 from 640, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 13:
666 goes into 6400 9 times with a remainder of 406.
Use 9 as the next digit of our solution. 
Result so far: 5758.109609
Deduct 5994 from 6400 and we're left with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Moving on to step 14:
666 goes into 4060 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 5758.1096096
If we take 3996 away from 4060, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 15:
The number 666 fits into 640 0 times, leaving a remainder of 640.
The next digit of our result is 0. 
Result so far: 5758.1096096
Deduct 0 from 640 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The quotient of the division is 5758.1096096, and the remainder is 6.4e-07.
