We're dividing 2267609 by 644 
Let's see how many times 644 fits into 2267609.

Going ahead to step 1:
644 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 644

Advancing to step 2:
When dividing 22 by 644, we get 0 with a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Append the next digit (6) from the dividend to 22 and continue with: 226 / 644

Going ahead to step 3:
The number 644 fits into 226 0 times, leaving a remainder of 226.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 226 after subtracting 0 from 226.
Take the next digit (7) from the dividend and append it to 226, then repeat: 2267 / 644

Advancing to step 4:
2267 divided by 644 is 3 with a remainder of 335.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 1932 from 2267 to get 335.
Append the next digit (6) from the dividend to 335 and continue with: 3356 / 644

Step 5:
When dividing 3356 by 644, we get 5 with a remainder of 136.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Deduct 3220 from 3356 and we're left with 136.
Grab the next digit (0) from the dividend, add it to 136, then carry on: 1360 / 644

Moving on to step 6:
644 can be fit into 1360 2 times, resulting in a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 352.0
Subtract 1288 from 1360 to get 72.
Take the next digit (9) from the dividend and append it to 72, then repeat: 729 / 644

Advancing to step 7:
If we divide 729 by 644, we get 1 and a remainder of 85.
Record the quotient 1 as the next digit in the result. 
Result so far: 3521.0
Subtract 644 from 729 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 8:
When dividing 850 by 644, we get 1 with a remainder of 206.
Use 1 as the next digit of our solution. 
Result so far: 3521.1
If we take 644 away from 850, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 9:
644 can be fit into 2060 3 times, resulting in a remainder of 128.
The next digit of our result is 3. 
Result so far: 3521.13
The remainder is 128 after subtracting 1932 from 2060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 10:
If we divide 1280 by 644, we get 1 and a remainder of 636.
The number 1 becomes the next digit in our result. 
Result so far: 3521.131
If we take 644 away from 1280, we end up with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Moving on to step 11:
When dividing 6360 by 644, we get 9 with a remainder of 564.
Use 9 as the next digit of our solution. 
Result so far: 3521.1319
If we take 5796 away from 6360, we end up with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Step 12:
If we divide 5640 by 644, we get 8 and a remainder of 488.
The number 8 becomes the next digit in our result. 
Result so far: 3521.13198
Deduct 5152 from 5640 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Moving on to step 13:
644 can be fit into 4880 7 times, resulting in a remainder of 372.
Record the quotient 7 as the next digit in the result. 
Result so far: 3521.131987
If we subtract 4508 from 4880, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 14:
When dividing 3720 by 644, we get 5 with a remainder of 500.
Record the quotient 5 as the next digit in the result. 
Result so far: 3521.1319875
Subtracting 3220 from 3720 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 15:
644 goes into 5000 7 times with a remainder of 492.
Use 7 as the next digit of our solution. 
Result so far: 3521.13198757
The remainder is 492 after subtracting 4508 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Our division results in 3521.13198757 with a remaining 4.92e-07.
