Let's divide 63889221 by 129
We want to divide 63889221 by 129.

On to step 1:
When dividing 6 by 129, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 129

Advancing to step 2:
The number 129 fits into 63 0 times, leaving a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Fetch the next digit (8) from the dividend, attach it to 63 and continue: 638 / 129

Going ahead to step 3:
129 can be fit into 638 4 times, resulting in a remainder of 122.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 516 from 638, we get 122.
Grab the next digit (8) from the dividend, add it to 122, then carry on: 1228 / 129

Moving on to step 4:
129 goes into 1228 9 times with a remainder of 67.
Use 9 as the next digit of our solution. 
Result so far: 49.0
If we take 1161 away from 1228, we end up with 67.
Include the next digit (9) from the dividend after 67, then repeat: 679 / 129

On to step 5:
129 goes into 679 5 times with a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 495.0
Deduct 645 from 679 and we're left with 34.
Fetch the next digit (2) from the dividend, attach it to 34 and continue: 342 / 129

Step 6:
The number 129 fits into 342 2 times, leaving a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 4952.0
Subtracting 258 from 342 leaves us with 84.
Append the next digit (2) from the dividend to 84 and continue with: 842 / 129

On to step 7:
842 divided by 129 is 6 with a remainder of 68.
Write down 6 as next digit of the result. 
Result so far: 49526.0
If we subtract 774 from 842, we get 68.
Grab the next digit (1) from the dividend, add it to 68, then carry on: 681 / 129

Let's proceed to step 8:
If we divide 681 by 129, we get 5 and a remainder of 36.
The number 5 becomes the next digit in our result. 
Result so far: 495265.0
If we take 645 away from 681, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
If we divide 360 by 129, we get 2 and a remainder of 102.
Put 2 as the next digit of the answer. 
Result so far: 495265.2
Deduct 258 from 360 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 10:
129 goes into 1020 7 times with a remainder of 117.
Use 7 as the next digit of our solution. 
Result so far: 495265.27
Deduct 903 from 1020 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Going ahead to step 11:
The number 129 fits into 1170 9 times, leaving a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 495265.279
Subtract 1161 from 1170 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 12:
129 goes into 90 0 times with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 495265.279
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 13:
When dividing 900 by 129, we get 6 with a remainder of 126.
Record the quotient 6 as the next digit in the result. 
Result so far: 495265.27906
Subtracting 774 from 900 leaves us 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.

Moving on to step 14:
If we divide 1260 by 129, we get 9 and a remainder of 99.
The next digit of our result is 9. 
Result so far: 495265.279069
Deduct 1161 from 1260 and we're left 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.

Step 15:
129 goes into 990 7 times with a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 495265.2790697
The remainder is 87 after subtracting 903 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 16:
If we divide 870 by 129, we get 6 and a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 495265.27906976
If we take 774 away from 870, we end up 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.

In conclusion, the division gives 495265.27906976 with a balance of 9.6e-08.
