We divide 12644486 by 129
We're looking to find how many times 129 goes into 12644486.

Let's proceed to step 1:
1 divided by 129 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 129

Going ahead to step 2:
129 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 129

Going ahead to step 3:
If we divide 126 by 129, we get 0 and a remainder of 126.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 126, we end up with 126.
Grab the next digit (4) from the dividend, add it to 126, then carry on: 1264 / 129

On to step 4:
1264 divided by 129 is 9 with a remainder of 103.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 103 after subtracting 1161 from 1264.
Bring next digit (4) of the dividend behind the 103 and repeat the process: 1034 / 129

Going ahead to step 5:
129 can be fit into 1034 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 98.0
Deduct 1032 from 1034 and we're left with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 129

Let's proceed to step 6:
129 goes into 24 0 times with a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 980.0
Deduct 0 from 24 and we're left with 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 129

On to step 7:
The number 129 fits into 248 1 times, leaving a remainder of 119.
Write down 1 as next digit of the result. 
Result so far: 9801.0
Subtract 129 from 248 to get 119.
Bring next digit (6) of the dividend behind the 119 and repeat the process: 1196 / 129

Step 8:
129 goes into 1196 9 times with a remainder of 35.
The next digit of our result is 9. 
Result so far: 98019.0
Subtracting 1161 from 1196 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
129 can be fit into 350 2 times, resulting in a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 98019.2
Subtracting 258 from 350 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 10:
920 divided by 129 is 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 98019.27
If we take 903 away from 920, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 11:
When dividing 170 by 129, we get 1 with a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 98019.271
Subtracting 129 from 170 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 12:
The number 129 fits into 410 3 times, leaving a remainder of 23.
The next digit of our result is 3. 
Result so far: 98019.2713
Deduct 387 from 410 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 13:
If we divide 230 by 129, we get 1 and a remainder of 101.
The number 1 becomes the next digit in our result. 
Result so far: 98019.27131
The remainder is 101 after subtracting 129 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Moving on to step 14:
129 can be fit into 1010 7 times, resulting in a remainder of 107.
Write down 7 as next digit of the result. 
Result so far: 98019.271317
Deduct 903 from 1010 and we're left with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 15:
When dividing 1070 by 129, we get 8 with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 98019.2713178
Subtracting 1032 from 1070 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 16:
When dividing 380 by 129, we get 2 with a remainder of 122.
The number 2 becomes the next digit in our result. 
Result so far: 98019.27131782
Deduct 258 from 380 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

The final outcome is 98019.27131782, with a leftover of 1.22e-07.
