Let's divide 46400843 by 999
We're looking to find how many times 999 goes into 46400843.

Step 1:
If we divide 4 by 999, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 999

Let's proceed to step 2:
If we divide 46 by 999, we get 0 and a remainder of 46.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 46 leaves us with 46.
Append the next digit (4) from the dividend to 46 and continue with: 464 / 999

Advancing to step 3:
464 divided by 999 is 0 with a remainder of 464.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 464 and we're left with 464.
Fetch the next digit (0) from the dividend, attach it to 464 and continue: 4640 / 999

Moving on to step 4:
If we divide 4640 by 999, we get 4 and a remainder of 644.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 3996 from 4640 to get 644.
Take the next digit (0) from the dividend and append it to 644, then repeat: 6440 / 999

Going ahead to step 5:
When dividing 6440 by 999, we get 6 with a remainder of 446.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we subtract 5994 from 6440, we get 446.
Bring next digit (8) of the dividend behind the 446 and repeat the process: 4468 / 999

Advancing to step 6:
4468 divided by 999 is 4 with a remainder of 472.
Put 4 as the next digit of the answer. 
Result so far: 464.0
If we subtract 3996 from 4468, we get 472.
Include the next digit (4) from the dividend after 472, then repeat: 4724 / 999

Advancing to step 7:
999 goes into 4724 4 times with a remainder of 728.
Write down 4 as next digit of the result. 
Result so far: 4644.0
If we take 3996 away from 4724, we end up with 728.
Append the next digit (3) from the dividend to 728 and continue with: 7283 / 999

Going ahead to step 8:
The number 999 fits into 7283 7 times, leaving a remainder of 290.
Record the quotient 7 as the next digit in the result. 
Result so far: 46447.0
Subtracting 6993 from 7283 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 9:
When dividing 2900 by 999, we get 2 with a remainder of 902.
The number 2 becomes the next digit in our result. 
Result so far: 46447.2
If we take 1998 away from 2900, we end up with 902.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9020, and continue the process.

Moving on to step 10:
999 can be fit into 9020 9 times, resulting in a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 46447.29
The remainder is 29 after subtracting 8991 from 9020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 11:
When dividing 290 by 999, we get 0 with a remainder of 290.
Record the quotient 0 as the next digit in the result. 
Result so far: 46447.29
Subtracting 0 from 290 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 12:
If we divide 2900 by 999, we get 2 and a remainder of 902.
Write down 2 as next digit of the result. 
Result so far: 46447.2902
The remainder is 902 after subtracting 1998 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9020, and continue the process.

Let's proceed to step 13:
The number 999 fits into 9020 9 times, leaving a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 46447.29029
Deduct 8991 from 9020 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 14:
If we divide 290 by 999, we get 0 and a remainder of 290.
The number 0 becomes the next digit in our result. 
Result so far: 46447.29029
If we subtract 0 from 290, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 15:
When dividing 2900 by 999, we get 2 with a remainder of 902.
The next digit of our result is 2. 
Result so far: 46447.2902902
If we take 1998 away from 2900, we end up with 902.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9020, and continue the process.

On to step 16:
When dividing 9020 by 999, we get 9 with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 46447.29029029
If we subtract 8991 from 9020, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The quotient of the division is 46447.29029029, and the remainder is 2.9e-08.
