Let's divide 40434853 by 999
Let's see how many times 999 fits into 40434853.

Step 1:
If we divide 4 by 999, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 999

Let's proceed to step 2:
999 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Bring next digit (4) of the dividend behind the 40 and repeat the process: 404 / 999

Going ahead to step 3:
999 goes into 404 0 times with a remainder of 404.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 404 and we're left with 404.
Grab the next digit (3) from the dividend, add it to 404, then carry on: 4043 / 999

Advancing to step 4:
4043 divided by 999 is 4 with a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 3996 from 4043 leaves us with 47.
Bring next digit (4) of the dividend behind the 47 and repeat the process: 474 / 999

Moving on to step 5:
The number 999 fits into 474 0 times, leaving a remainder of 474.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Deduct 0 from 474 and we're left with 474.
Bring next digit (8) of the dividend behind the 474 and repeat the process: 4748 / 999

Going ahead to step 6:
If we divide 4748 by 999, we get 4 and a remainder of 752.
Use 4 as the next digit of our solution. 
Result so far: 404.0
Deduct 3996 from 4748 and we're left with 752.
Append the next digit (5) from the dividend to 752 and continue with: 7525 / 999

Going ahead to step 7:
7525 divided by 999 is 7 with a remainder of 532.
Use 7 as the next digit of our solution. 
Result so far: 4047.0
Subtracting 6993 from 7525 leaves us with 532.
Fetch the next digit (3) from the dividend, attach it to 532 and continue: 5323 / 999

On to step 8:
When dividing 5323 by 999, we get 5 with a remainder of 328.
Put 5 as the next digit of the answer. 
Result so far: 40475.0
The remainder is 328 after subtracting 4995 from 5323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 9:
999 goes into 3280 3 times with a remainder of 283.
Record the quotient 3 as the next digit in the result. 
Result so far: 40475.3
The remainder is 283 after subtracting 2997 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Moving on to step 10:
The number 999 fits into 2830 2 times, leaving a remainder of 832.
Use 2 as the next digit of our solution. 
Result so far: 40475.32
Deduct 1998 from 2830 and we're left with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Moving on to step 11:
8320 divided by 999 is 8 with a remainder of 328.
The next digit of our result is 8. 
Result so far: 40475.328
If we subtract 7992 from 8320, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 12:
If we divide 3280 by 999, we get 3 and a remainder of 283.
Record the quotient 3 as the next digit in the result. 
Result so far: 40475.3283
Subtracting 2997 from 3280 leaves us with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Going ahead to step 13:
When dividing 2830 by 999, we get 2 with a remainder of 832.
The number 2 becomes the next digit in our result. 
Result so far: 40475.32832
Deduct 1998 from 2830 and we're left with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Moving on to step 14:
The number 999 fits into 8320 8 times, leaving a remainder of 328.
The next digit of our result is 8. 
Result so far: 40475.328328
If we subtract 7992 from 8320, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 15:
When dividing 3280 by 999, we get 3 with a remainder of 283.
The number 3 becomes the next digit in our result. 
Result so far: 40475.3283283
If we take 2997 away from 3280, we end up with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

On to step 16:
2830 divided by 999 is 2 with a remainder of 832.
Write down 2 as next digit of the result. 
Result so far: 40475.32832832
Deduct 1998 from 2830 and we're left with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

The quotient of the division is 40475.32832832, and the remainder is 8.32e-07.
