12900004 ÷ 325 
Our goal is to divide 12900004 by 325.

Moving on to step 1:
325 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 325

Advancing to step 2:
325 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 325

Advancing to step 3:
325 can be fit into 129 0 times, resulting in a remainder of 129.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 129 and we're left with 129.
Fetch the next digit (0) from the dividend, attach it to 129 and continue: 1290 / 325

Moving on to step 4:
When dividing 1290 by 325, we get 3 with a remainder of 315.
The next digit of our result is 3. 
Result so far: 3.0
If we take 975 away from 1290, we end up with 315.
Include the next digit (0) from the dividend after 315, then repeat: 3150 / 325

On to step 5:
3150 divided by 325 is 9 with a remainder of 225.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we subtract 2925 from 3150, we get 225.
Fetch the next digit (0) from the dividend, attach it to 225 and continue: 2250 / 325

Going ahead to step 6:
2250 divided by 325 is 6 with a remainder of 300.
Write down 6 as next digit of the result. 
Result so far: 396.0
Subtract 1950 from 2250 to get 300.
Grab the next digit (0) from the dividend, add it to 300, then carry on: 3000 / 325

Let's proceed to step 7:
325 can be fit into 3000 9 times, resulting in a remainder of 75.
Write down 9 as next digit of the result. 
Result so far: 3969.0
If we take 2925 away from 3000, we end up with 75.
Take the next digit (4) from the dividend and append it to 75, then repeat: 754 / 325

Let's proceed to step 8:
If we divide 754 by 325, we get 2 and a remainder of 104.
Record the quotient 2 as the next digit in the result. 
Result so far: 39692.0
Subtracting 650 from 754 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 9:
The number 325 fits into 1040 3 times, leaving a remainder of 65.
The number 3 becomes the next digit in our result. 
Result so far: 39692.3
Deduct 975 from 1040 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 10:
650 divided by 325 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 39692.32
Subtract 650 from 650 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
The number 325 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 39692.32
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
The number 325 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 39692.32
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 39692.32 and a remainder of 0.0.
