We divide 43641809 by 109
We want to figure out the number of times 43641809 can be divided by 109.

Moving on to step 1:
4 divided by 109 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 109

Step 2:
If we divide 43 by 109, we get 0 and a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 109

On to step 3:
The number 109 fits into 436 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 436 away from 436, we end up with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 109

On to step 4:
109 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 109

On to step 5:
109 can be fit into 41 0 times, resulting in a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 400.0
Deduct 0 from 41 and we're left with 41.
Take the next digit (8) from the dividend and append it to 41, then repeat: 418 / 109

Going ahead to step 6:
418 divided by 109 is 3 with a remainder of 91.
Put 3 as the next digit of the answer. 
Result so far: 4003.0
The remainder is 91 after subtracting 327 from 418.
Include the next digit (0) from the dividend after 91, then repeat: 910 / 109

Let's proceed to step 7:
If we divide 910 by 109, we get 8 and a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 40038.0
Subtract 872 from 910 to get 38.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 109

Step 8:
389 divided by 109 is 3 with a remainder of 62.
The next digit of our result is 3. 
Result so far: 400383.0
If we take 327 away from 389, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 9:
109 goes into 620 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 400383.5
The remainder is 75 after subtracting 545 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 10:
The number 109 fits into 750 6 times, leaving a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 400383.56
The remainder is 96 after subtracting 654 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 11:
109 can be fit into 960 8 times, resulting in a remainder of 88.
Put 8 as the next digit of the answer. 
Result so far: 400383.568
Deduct 872 from 960 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 12:
The number 109 fits into 880 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 400383.5688
If we take 872 away from 880, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 400383.5688 with a balance of 8e-05.
