We're dividing 30433987 by 999 
We want to divide 30433987 by 999.

Going ahead to step 1:
999 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 999

Advancing to step 2:
999 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 999

Going ahead to step 3:
304 divided by 999 is 0 with a remainder of 304.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 304 leaves us with 304.
Include the next digit (3) from the dividend after 304, then repeat: 3043 / 999

Let's proceed to step 4:
3043 divided by 999 is 3 with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 2997 from 3043 to get 46.
Fetch the next digit (3) from the dividend, attach it to 46 and continue: 463 / 999

Moving on to step 5:
463 divided by 999 is 0 with a remainder of 463.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
The remainder is 463 after subtracting 0 from 463.
Take the next digit (9) from the dividend and append it to 463, then repeat: 4639 / 999

On to step 6:
999 goes into 4639 4 times with a remainder of 643.
The number 4 becomes the next digit in our result. 
Result so far: 304.0
Subtract 3996 from 4639 to get 643.
Fetch the next digit (8) from the dividend, attach it to 643 and continue: 6438 / 999

On to step 7:
The number 999 fits into 6438 6 times, leaving a remainder of 444.
Put 6 as the next digit of the answer. 
Result so far: 3046.0
If we subtract 5994 from 6438, we get 444.
Take the next digit (7) from the dividend and append it to 444, then repeat: 4447 / 999

On to step 8:
999 can be fit into 4447 4 times, resulting in a remainder of 451.
Record the quotient 4 as the next digit in the result. 
Result so far: 30464.0
The remainder is 451 after subtracting 3996 from 4447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Let's proceed to step 9:
The number 999 fits into 4510 4 times, leaving a remainder of 514.
Write down 4 as next digit of the result. 
Result so far: 30464.4
If we subtract 3996 from 4510, we get 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Moving on to step 10:
999 can be fit into 5140 5 times, resulting in a remainder of 145.
The next digit of our result is 5. 
Result so far: 30464.45
Subtract 4995 from 5140 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 11:
999 can be fit into 1450 1 times, resulting in a remainder of 451.
Use 1 as the next digit of our solution. 
Result so far: 30464.451
If we take 999 away from 1450, we end up with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Going ahead to step 12:
999 can be fit into 4510 4 times, resulting in a remainder of 514.
Put 4 as the next digit of the answer. 
Result so far: 30464.4514
Deduct 3996 from 4510 and we're left with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Going ahead to step 13:
The number 999 fits into 5140 5 times, leaving a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 30464.45145
Subtracting 4995 from 5140 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 14:
The number 999 fits into 1450 1 times, leaving a remainder of 451.
The number 1 becomes the next digit in our result. 
Result so far: 30464.451451
Deduct 999 from 1450 and we're left with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Going ahead to step 15:
If we divide 4510 by 999, we get 4 and a remainder of 514.
Use 4 as the next digit of our solution. 
Result so far: 30464.4514514
If we subtract 3996 from 4510, we get 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Moving on to step 16:
5140 divided by 999 is 5 with a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 30464.45145145
Deduct 4995 from 5140 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The final outcome is 30464.45145145, with a leftover of 1.45e-07.
