We look at the division of 643509 by 44 
We're looking to find how many times 44 goes into 643509.

Going ahead to step 1:
44 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 44

On to step 2:
When dividing 64 by 44, we get 1 with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 44 away from 64, we end up with 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 44

Let's proceed to step 3:
44 goes into 203 4 times with a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 176 from 203, we get 27.
Append the next digit (5) from the dividend to 27 and continue with: 275 / 44

Moving on to step 4:
44 goes into 275 6 times with a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 146.0
The remainder is 11 after subtracting 264 from 275.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 44

Advancing to step 5:
If we divide 110 by 44, we get 2 and a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 1462.0
If we take 88 away from 110, we end up with 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 44

On to step 6:
The number 44 fits into 229 5 times, leaving a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 14625.0
If we subtract 220 from 229, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
44 goes into 90 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 14625.2
Subtract 88 from 90 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
44 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 14625.2
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
44 can be fit into 200 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 14625.204
Subtract 176 from 200 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
44 can be fit into 240 5 times, resulting in a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 14625.2045
Deduct 220 from 240 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
200 divided by 44 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 14625.20454
Subtracting 176 from 200 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
When dividing 240 by 44, we get 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 14625.204545
If we subtract 220 from 240, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
When dividing 200 by 44, we get 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 14625.2045454
If we take 176 away from 200, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 14:
44 goes into 240 5 times with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 14625.20454545
Deduct 220 from 240 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 14625.20454545, with a leftover of 2e-08.
