We divide 45091258 by 129
We want to figure out the number of times 45091258 can be divided by 129.

Advancing to step 1:
The number 129 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 129

Let's proceed to step 2:
129 can be fit into 45 0 times, resulting in a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 129

Going ahead to step 3:
129 can be fit into 450 3 times, resulting in a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 387 from 450 and we're left with 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 129

Moving on to step 4:
If we divide 639 by 129, we get 4 and a remainder of 123.
Put 4 as the next digit of the answer. 
Result so far: 34.0
If we subtract 516 from 639, we get 123.
Include the next digit (1) from the dividend after 123, then repeat: 1231 / 129

On to step 5:
129 can be fit into 1231 9 times, resulting in a remainder of 70.
The number 9 becomes the next digit in our result. 
Result so far: 349.0
The remainder is 70 after subtracting 1161 from 1231.
Take the next digit (2) from the dividend and append it to 70, then repeat: 702 / 129

Advancing to step 6:
129 goes into 702 5 times with a remainder of 57.
Use 5 as the next digit of our solution. 
Result so far: 3495.0
If we subtract 645 from 702, we get 57.
Fetch the next digit (5) from the dividend, attach it to 57 and continue: 575 / 129

Let's proceed to step 7:
575 divided by 129 is 4 with a remainder of 59.
The next digit of our result is 4. 
Result so far: 34954.0
Subtracting 516 from 575 leaves us with 59.
Grab the next digit (8) from the dividend, add it to 59, then carry on: 598 / 129

Let's proceed to step 8:
129 can be fit into 598 4 times, resulting in a remainder of 82.
The number 4 becomes the next digit in our result. 
Result so far: 349544.0
The remainder is 82 after subtracting 516 from 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 9:
When dividing 820 by 129, we get 6 with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 349544.6
If we take 774 away from 820, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
129 can be fit into 460 3 times, resulting in a remainder of 73.
The next digit of our result is 3. 
Result so far: 349544.63
If we take 387 away from 460, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 11:
129 can be fit into 730 5 times, resulting in a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 349544.635
Deduct 645 from 730 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 12:
850 divided by 129 is 6 with a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 349544.6356
Subtracting 774 from 850 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 13:
129 goes into 760 5 times with a remainder of 115.
Write down 5 as next digit of the result. 
Result so far: 349544.63565
The remainder is 115 after subtracting 645 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 14:
129 can be fit into 1150 8 times, resulting in a remainder of 118.
Put 8 as the next digit of the answer. 
Result so far: 349544.635658
If we take 1032 away from 1150, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 15:
When dividing 1180 by 129, we get 9 with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 349544.6356589
Subtracting 1161 from 1180 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 16:
If we divide 190 by 129, we get 1 and a remainder of 61.
Write down 1 as next digit of the result. 
Result so far: 349544.63565891
Subtract 129 from 190 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Our division results in 349544.63565891 with a remaining 6.1e-08.
