46395001 ÷ 999 
Let's see how many times 999 fits into 46395001.

Moving on to step 1:
The number 999 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 999

Moving on to step 2:
999 can be fit into 46 0 times, resulting in a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 46, we get 46.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 999

Going ahead to step 3:
If we divide 463 by 999, we get 0 and a remainder of 463.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 463 after subtracting 0 from 463.
Include the next digit (9) from the dividend after 463, then repeat: 4639 / 999

Step 4:
If we divide 4639 by 999, we get 4 and a remainder of 643.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 3996 from 4639 leaves us with 643.
Bring next digit (5) of the dividend behind the 643 and repeat the process: 6435 / 999

Going ahead to step 5:
If we divide 6435 by 999, we get 6 and a remainder of 441.
Write down 6 as next digit of the result. 
Result so far: 46.0
The remainder is 441 after subtracting 5994 from 6435.
Grab the next digit (0) from the dividend, add it to 441, then carry on: 4410 / 999

Moving on to step 6:
4410 divided by 999 is 4 with a remainder of 414.
Use 4 as the next digit of our solution. 
Result so far: 464.0
Deduct 3996 from 4410 and we're left with 414.
Fetch the next digit (0) from the dividend, attach it to 414 and continue: 4140 / 999

Moving on to step 7:
When dividing 4140 by 999, we get 4 with a remainder of 144.
Record the quotient 4 as the next digit in the result. 
Result so far: 4644.0
If we take 3996 away from 4140, we end up with 144.
Take the next digit (1) from the dividend and append it to 144, then repeat: 1441 / 999

Moving on to step 8:
If we divide 1441 by 999, we get 1 and a remainder of 442.
Use 1 as the next digit of our solution. 
Result so far: 46441.0
Deduct 999 from 1441 and we're left with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Let's proceed to step 9:
When dividing 4420 by 999, we get 4 with a remainder of 424.
The number 4 becomes the next digit in our result. 
Result so far: 46441.4
Deduct 3996 from 4420 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 10:
999 can be fit into 4240 4 times, resulting in a remainder of 244.
The number 4 becomes the next digit in our result. 
Result so far: 46441.44
Deduct 3996 from 4240 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

The final result is 46441.44 with a remainder of 0.244.
