12228878 ÷ 129 
We want to figure out the number of times 12228878 can be divided by 129.

Step 1:
If we divide 1 by 129, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 129

Going ahead to step 2:
If we divide 12 by 129, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 129

Let's proceed to step 3:
When dividing 122 by 129, we get 0 with a remainder of 122.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 122 and we're left with 122.
Fetch the next digit (2) from the dividend, attach it to 122 and continue: 1222 / 129

Let's proceed to step 4:
129 can be fit into 1222 9 times, resulting in a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 1161 from 1222 leaves us with 61.
Take the next digit (8) from the dividend and append it to 61, then repeat: 618 / 129

On to step 5:
618 divided by 129 is 4 with a remainder of 102.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
If we subtract 516 from 618, we get 102.
Append the next digit (8) from the dividend to 102 and continue with: 1028 / 129

Moving on to step 6:
129 goes into 1028 7 times with a remainder of 125.
Record the quotient 7 as the next digit in the result. 
Result so far: 947.0
Subtract 903 from 1028 to get 125.
Fetch the next digit (7) from the dividend, attach it to 125 and continue: 1257 / 129

On to step 7:
If we divide 1257 by 129, we get 9 and a remainder of 96.
Write down 9 as next digit of the result. 
Result so far: 9479.0
If we take 1161 away from 1257, we end up with 96.
Include the next digit (8) from the dividend after 96, then repeat: 968 / 129

On to step 8:
129 can be fit into 968 7 times, resulting in a remainder of 65.
Write down 7 as next digit of the result. 
Result so far: 94797.0
Subtract 903 from 968 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 9:
If we divide 650 by 129, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 94797.5
If we subtract 645 from 650, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
129 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 94797.5
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
When dividing 500 by 129, we get 3 with a remainder of 113.
Record the quotient 3 as the next digit in the result. 
Result so far: 94797.503
The remainder is 113 after subtracting 387 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Advancing to step 12:
1130 divided by 129 is 8 with a remainder of 98.
Record the quotient 8 as the next digit in the result. 
Result so far: 94797.5038
Subtract 1032 from 1130 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 13:
129 can be fit into 980 7 times, resulting in a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 94797.50387
If we subtract 903 from 980, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 14:
129 goes into 770 5 times with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 94797.503875
Subtracting 645 from 770 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 15:
129 goes into 1250 9 times with a remainder of 89.
The next digit of our result is 9. 
Result so far: 94797.5038759
If we subtract 1161 from 1250, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 16:
The number 129 fits into 890 6 times, leaving a remainder of 116.
The number 6 becomes the next digit in our result. 
Result so far: 94797.50387596
Subtracting 774 from 890 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

In conclusion, the division gives 94797.50387596 with a balance of 1.16e-07.
