Let's divide 41392110 by 129
We want to figure out the number of times 41392110 can be divided by 129.

On to step 1:
When dividing 4 by 129, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 129

Moving on to step 2:
When dividing 41 by 129, we get 0 with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 41, we end up with 41.
Include the next digit (3) from the dividend after 41, then repeat: 413 / 129

Moving on to step 3:
The number 129 fits into 413 3 times, leaving a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 387 from 413 to get 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 129

Let's proceed to step 4:
The number 129 fits into 269 2 times, leaving a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
If we take 258 away from 269, we end up with 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 129

Step 5:
129 can be fit into 112 0 times, resulting in a remainder of 112.
Use 0 as the next digit of our solution. 
Result so far: 320.0
If we take 0 away from 112, we end up with 112.
Include the next digit (1) from the dividend after 112, then repeat: 1121 / 129

Let's proceed to step 6:
1121 divided by 129 is 8 with a remainder of 89.
Put 8 as the next digit of the answer. 
Result so far: 3208.0
Deduct 1032 from 1121 and we're left with 89.
Include the next digit (1) from the dividend after 89, then repeat: 891 / 129

Moving on to step 7:
129 can be fit into 891 6 times, resulting in a remainder of 117.
Use 6 as the next digit of our solution. 
Result so far: 32086.0
The remainder is 117 after subtracting 774 from 891.
Take the next digit (0) from the dividend and append it to 117, then repeat: 1170 / 129

On to step 8:
129 goes into 1170 9 times with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 320869.0
Subtracting 1161 from 1170 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
The number 129 fits into 90 0 times, leaving a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 320869.0
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
900 divided by 129 is 6 with a remainder of 126.
The next digit of our result is 6. 
Result so far: 320869.06
Deduct 774 from 900 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 11:
When dividing 1260 by 129, we get 9 with a remainder of 99.
Use 9 as the next digit of our solution. 
Result so far: 320869.069
Subtracting 1161 from 1260 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 12:
The number 129 fits into 990 7 times, leaving a remainder of 87.
The number 7 becomes the next digit in our result. 
Result so far: 320869.0697
Subtracting 903 from 990 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 13:
870 divided by 129 is 6 with a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 320869.06976
Subtracting 774 from 870 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 14:
129 can be fit into 960 7 times, resulting in a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 320869.069767
The remainder is 57 after subtracting 903 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 15:
570 divided by 129 is 4 with a remainder of 54.
The next digit of our result is 4. 
Result so far: 320869.0697674
Subtracting 516 from 570 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 16:
129 goes into 540 4 times with a remainder of 24.
The next digit of our result is 4. 
Result so far: 320869.06976744
The remainder is 24 after subtracting 516 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 320869.06976744 and a remainder of 2.4e-08.
