6440353 divided by 145 
Our goal is to divide 6440353 by 145.

Let's proceed to step 1:
145 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 145

Let's proceed to step 2:
145 goes into 64 0 times with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 145

Going ahead to step 3:
When dividing 644 by 145, we get 4 with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 580 from 644 leaves us with 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 145

Moving on to step 4:
640 divided by 145 is 4 with a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
The remainder is 60 after subtracting 580 from 640.
Bring next digit (3) of the dividend behind the 60 and repeat the process: 603 / 145

Advancing to step 5:
603 divided by 145 is 4 with a remainder of 23.
The next digit of our result is 4. 
Result so far: 444.0
Deduct 580 from 603 and we're left with 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 145

Let's proceed to step 6:
145 goes into 235 1 times with a remainder of 90.
The number 1 becomes the next digit in our result. 
Result so far: 4441.0
Subtract 145 from 235 to get 90.
Bring next digit (3) of the dividend behind the 90 and repeat the process: 903 / 145

Let's proceed to step 7:
If we divide 903 by 145, we get 6 and a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 44416.0
Deduct 870 from 903 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 8:
145 can be fit into 330 2 times, resulting in a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 44416.2
Subtracting 290 from 330 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
145 can be fit into 400 2 times, resulting in a remainder of 110.
The next digit of our result is 2. 
Result so far: 44416.22
Subtracting 290 from 400 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

After the division, we end up with 44416.22 and a remainder of 0.11.
