Let's divide 5531384 by 129
Our goal is to divide 5531384 by 129.

On to step 1:
129 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 129

Moving on to step 2:
If we divide 55 by 129, we get 0 and a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Fetch the next digit (3) from the dividend, attach it to 55 and continue: 553 / 129

Let's proceed to step 3:
129 goes into 553 4 times with a remainder of 37.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 516 from 553 leaves us with 37.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 129

Going ahead to step 4:
371 divided by 129 is 2 with a remainder of 113.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
The remainder is 113 after subtracting 258 from 371.
Fetch the next digit (3) from the dividend, attach it to 113 and continue: 1133 / 129

Moving on to step 5:
129 can be fit into 1133 8 times, resulting in a remainder of 101.
The next digit of our result is 8. 
Result so far: 428.0
Subtract 1032 from 1133 to get 101.
Fetch the next digit (8) from the dividend, attach it to 101 and continue: 1018 / 129

On to step 6:
The number 129 fits into 1018 7 times, leaving a remainder of 115.
The next digit of our result is 7. 
Result so far: 4287.0
If we take 903 away from 1018, we end up with 115.
Bring next digit (4) of the dividend behind the 115 and repeat the process: 1154 / 129

Moving on to step 7:
1154 divided by 129 is 8 with a remainder of 122.
Put 8 as the next digit of the answer. 
Result so far: 42878.0
The remainder is 122 after subtracting 1032 from 1154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 8:
1220 divided by 129 is 9 with a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 42878.9
If we subtract 1161 from 1220, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 9:
If we divide 590 by 129, we get 4 and a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 42878.94
Deduct 516 from 590 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 10:
If we divide 740 by 129, we get 5 and a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 42878.945
Deduct 645 from 740 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 11:
The number 129 fits into 950 7 times, leaving a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 42878.9457
The remainder is 47 after subtracting 903 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 12:
The number 129 fits into 470 3 times, leaving a remainder of 83.
Record the quotient 3 as the next digit in the result. 
Result so far: 42878.94573
Subtract 387 from 470 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 13:
129 can be fit into 830 6 times, resulting in a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 42878.945736
Subtract 774 from 830 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 14:
When dividing 560 by 129, we get 4 with a remainder of 44.
The next digit of our result is 4. 
Result so far: 42878.9457364
The remainder is 44 after subtracting 516 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 15:
The number 129 fits into 440 3 times, leaving a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 42878.94573643
The remainder is 53 after subtracting 387 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The final outcome is 42878.94573643, with a leftover of 5.3e-08.
