44373689 ÷ 129 
Our goal is to divide 44373689 by 129.

Let's proceed to step 1:
The number 129 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 129

Advancing to step 2:
129 goes into 44 0 times with a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 44, we end up with 44.
Grab the next digit (3) from the dividend, add it to 44, then carry on: 443 / 129

Moving on to step 3:
129 goes into 443 3 times with a remainder of 56.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 387 from 443, we get 56.
Include the next digit (7) from the dividend after 56, then repeat: 567 / 129

Step 4:
129 goes into 567 4 times with a remainder of 51.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
The remainder is 51 after subtracting 516 from 567.
Take the next digit (3) from the dividend and append it to 51, then repeat: 513 / 129

Let's proceed to step 5:
129 can be fit into 513 3 times, resulting in a remainder of 126.
The next digit of our result is 3. 
Result so far: 343.0
Subtract 387 from 513 to get 126.
Grab the next digit (6) from the dividend, add it to 126, then carry on: 1266 / 129

Step 6:
When dividing 1266 by 129, we get 9 with a remainder of 105.
Record the quotient 9 as the next digit in the result. 
Result so far: 3439.0
If we take 1161 away from 1266, we end up with 105.
Fetch the next digit (8) from the dividend, attach it to 105 and continue: 1058 / 129

Going ahead to step 7:
When dividing 1058 by 129, we get 8 with a remainder of 26.
The next digit of our result is 8. 
Result so far: 34398.0
If we take 1032 away from 1058, we end up with 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 129

Moving on to step 8:
129 goes into 269 2 times with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 343982.0
Deduct 258 from 269 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
110 divided by 129 is 0 with a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 343982.0
Subtracting 0 from 110 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.

Moving on to step 10:
When dividing 1100 by 129, we get 8 with a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 343982.08
If we take 1032 away from 1100, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 11:
If we divide 680 by 129, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 343982.085
Subtracting 645 from 680 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 12:
129 goes into 350 2 times with a remainder of 92.
Put 2 as the next digit of the answer. 
Result so far: 343982.0852
Deduct 258 from 350 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 13:
129 can be fit into 920 7 times, resulting in a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 343982.08527
The remainder is 17 after subtracting 903 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 14:
129 goes into 170 1 times with a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 343982.085271
If we subtract 129 from 170, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 15:
410 divided by 129 is 3 with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 343982.0852713
Deduct 387 from 410 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 16:
If we divide 230 by 129, we get 1 and a remainder of 101.
The number 1 becomes the next digit in our result. 
Result so far: 343982.08527131
If we subtract 129 from 230, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Our division results in 343982.08527131 with a remaining 1.01e-07.
