We're dividing 5866896 by 129 
Let's see how many times 129 fits into 5866896.

Advancing to step 1:
5 divided by 129 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 129

Moving on to step 2:
When dividing 58 by 129, we get 0 with a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 58 to get 58.
Append the next digit (6) from the dividend to 58 and continue with: 586 / 129

Going ahead to step 3:
129 goes into 586 4 times with a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 516 from 586 leaves us with 70.
Fetch the next digit (6) from the dividend, attach it to 70 and continue: 706 / 129

Advancing to step 4:
When dividing 706 by 129, we get 5 with a remainder of 61.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtract 645 from 706 to get 61.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 129

Step 5:
The number 129 fits into 618 4 times, leaving a remainder of 102.
Record the quotient 4 as the next digit in the result. 
Result so far: 454.0
The remainder is 102 after subtracting 516 from 618.
Fetch the next digit (9) from the dividend, attach it to 102 and continue: 1029 / 129

Let's proceed to step 6:
1029 divided by 129 is 7 with a remainder of 126.
Write down 7 as next digit of the result. 
Result so far: 4547.0
Deduct 903 from 1029 and we're left with 126.
Take the next digit (6) from the dividend and append it to 126, then repeat: 1266 / 129

Step 7:
If we divide 1266 by 129, we get 9 and a remainder of 105.
Record the quotient 9 as the next digit in the result. 
Result so far: 45479.0
If we take 1161 away from 1266, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 8:
1050 divided by 129 is 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 45479.8
Deduct 1032 from 1050 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
When dividing 180 by 129, we get 1 with a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 45479.81
Subtract 129 from 180 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 10:
129 can be fit into 510 3 times, resulting in a remainder of 123.
Put 3 as the next digit of the answer. 
Result so far: 45479.813
Deduct 387 from 510 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 11:
129 goes into 1230 9 times with a remainder of 69.
The next digit of our result is 9. 
Result so far: 45479.8139
Deduct 1161 from 1230 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 12:
129 can be fit into 690 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 45479.81395
If we take 645 away from 690, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 13:
450 divided by 129 is 3 with a remainder of 63.
The next digit of our result is 3. 
Result so far: 45479.813953
If we take 387 away from 450, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 14:
The number 129 fits into 630 4 times, leaving a remainder of 114.
The number 4 becomes the next digit in our result. 
Result so far: 45479.8139534
Deduct 516 from 630 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 15:
The number 129 fits into 1140 8 times, leaving a remainder of 108.
The number 8 becomes the next digit in our result. 
Result so far: 45479.81395348
If we take 1032 away from 1140, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Our division results in 45479.81395348 with a remaining 1.08e-07.
