Let's divide 2025411 by 645
Our goal is to divide 2025411 by 645.

Advancing to step 1:
When dividing 2 by 645, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 645

Advancing to step 2:
20 divided by 645 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 645

Going ahead to step 3:
The number 645 fits into 202 0 times, leaving a remainder of 202.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 202 leaves us with 202.
Bring next digit (5) of the dividend behind the 202 and repeat the process: 2025 / 645

Let's proceed to step 4:
2025 divided by 645 is 3 with a remainder of 90.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 1935 away from 2025, we end up with 90.
Include the next digit (4) from the dividend after 90, then repeat: 904 / 645

On to step 5:
645 can be fit into 904 1 times, resulting in a remainder of 259.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtracting 645 from 904 leaves us with 259.
Bring next digit (1) of the dividend behind the 259 and repeat the process: 2591 / 645

Step 6:
2591 divided by 645 is 4 with a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 314.0
Subtract 2580 from 2591 to get 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 645

On to step 7:
645 goes into 111 0 times with a remainder of 111.
The number 0 becomes the next digit in our result. 
Result so far: 3140.0
Deduct 0 from 111 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 8:
The number 645 fits into 1110 1 times, leaving a remainder of 465.
The number 1 becomes the next digit in our result. 
Result so far: 3140.1
If we subtract 645 from 1110, we get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Advancing to step 9:
645 goes into 4650 7 times with a remainder of 135.
The number 7 becomes the next digit in our result. 
Result so far: 3140.17
The remainder is 135 after subtracting 4515 from 4650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 10:
645 goes into 1350 2 times with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 3140.172
Deduct 1290 from 1350 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
645 can be fit into 600 0 times, resulting in a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 3140.172
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 12:
When dividing 6000 by 645, we get 9 with a remainder of 195.
Use 9 as the next digit of our solution. 
Result so far: 3140.17209
The remainder is 195 after subtracting 5805 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Advancing to step 13:
The number 645 fits into 1950 3 times, leaving a remainder of 15.
The next digit of our result is 3. 
Result so far: 3140.172093
Deduct 1935 from 1950 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
645 goes into 150 0 times with a remainder of 150.
The next digit of our result is 0. 
Result so far: 3140.172093
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 15:
645 can be fit into 1500 2 times, resulting in a remainder of 210.
The next digit of our result is 2. 
Result so far: 3140.17209302
Deduct 1290 from 1500 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final result is 3140.17209302 with a remainder of 2.1e-07.
