Let's divide 45871543 by 129
We want to divide 45871543 by 129.

Let's proceed to step 1:
If we divide 4 by 129, we get 0 and 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.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 129

Let's proceed to step 2:
129 goes into 45 0 times with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Bring next digit (8) of the dividend behind the 45 and repeat the process: 458 / 129

Step 3:
129 goes into 458 3 times with a remainder of 71.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 387 from 458, we get 71.
Take the next digit (7) from the dividend and append it to 71, then repeat: 717 / 129

On to step 4:
If we divide 717 by 129, we get 5 and a remainder of 72.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Subtract 645 from 717 to get 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 129

Moving on to step 5:
If we divide 721 by 129, we get 5 and a remainder of 76.
Use 5 as the next digit of our solution. 
Result so far: 355.0
If we take 645 away from 721, we end up with 76.
Bring next digit (5) of the dividend behind the 76 and repeat the process: 765 / 129

Let's proceed to step 6:
129 goes into 765 5 times with a remainder of 120.
The number 5 becomes the next digit in our result. 
Result so far: 3555.0
The remainder is 120 after subtracting 645 from 765.
Grab the next digit (4) from the dividend, add it to 120, then carry on: 1204 / 129

Step 7:
If we divide 1204 by 129, we get 9 and a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 35559.0
Deduct 1161 from 1204 and we're left with 43.
Grab the next digit (3) from the dividend, add it to 43, then carry on: 433 / 129

Step 8:
If we divide 433 by 129, we get 3 and a remainder of 46.
The next digit of our result is 3. 
Result so far: 355593.0
Subtracting 387 from 433 leaves us 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.

On to step 9:
When dividing 460 by 129, we get 3 with a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 355593.3
Subtract 387 from 460 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 10:
If we divide 730 by 129, we get 5 and a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 355593.35
If we subtract 645 from 730, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 11:
850 divided by 129 is 6 with a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 355593.356
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.

On to step 12:
129 can be fit into 760 5 times, resulting in a remainder of 115.
Use 5 as the next digit of our solution. 
Result so far: 355593.3565
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.

On to step 13:
When dividing 1150 by 129, we get 8 with a remainder of 118.
The next digit of our result is 8. 
Result so far: 355593.35658
Subtract 1032 from 1150 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 14:
When dividing 1180 by 129, we get 9 with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 355593.356589
If we subtract 1161 from 1180, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 15:
If we divide 190 by 129, we get 1 and a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 355593.3565891
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.

On to step 16:
129 can be fit into 610 4 times, resulting in a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 355593.35658914
The remainder is 94 after subtracting 516 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

In conclusion, the division gives 355593.35658914 with a balance of 9.4e-08.
