We divide 99351249 by 129
We want to figure out the number of times 99351249 can be divided by 129.

Let's proceed to step 1:
129 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 129

Let's proceed to step 2:
When dividing 99 by 129, we get 0 with a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Take the next digit (3) from the dividend and append it to 99, then repeat: 993 / 129

Moving on to step 3:
129 can be fit into 993 7 times, resulting in a remainder of 90.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 903 from 993, we get 90.
Append the next digit (5) from the dividend to 90 and continue with: 905 / 129

Going ahead to step 4:
When dividing 905 by 129, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Subtracting 903 from 905 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 129

Moving on to step 5:
129 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 770.0
If we subtract 0 from 21, we get 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 129

Step 6:
When dividing 212 by 129, we get 1 with a remainder of 83.
Put 1 as the next digit of the answer. 
Result so far: 7701.0
Deduct 129 from 212 and we're left with 83.
Bring next digit (4) of the dividend behind the 83 and repeat the process: 834 / 129

Step 7:
When dividing 834 by 129, we get 6 with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 77016.0
Deduct 774 from 834 and we're left with 60.
Take the next digit (9) from the dividend and append it to 60, then repeat: 609 / 129

Moving on to step 8:
The number 129 fits into 609 4 times, leaving a remainder of 93.
The number 4 becomes the next digit in our result. 
Result so far: 770164.0
If we take 516 away from 609, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 9:
129 goes into 930 7 times with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 770164.7
Deduct 903 from 930 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 10:
129 can be fit into 270 2 times, resulting in a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 770164.72
Subtracting 258 from 270 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
If we divide 120 by 129, we get 0 and a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 770164.72
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
1200 divided by 129 is 9 with a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 770164.7209
Deduct 1161 from 1200 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 13:
390 divided by 129 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 770164.72093
Deduct 387 from 390 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 14:
If we divide 30 by 129, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 770164.72093
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 15:
If we divide 300 by 129, we get 2 and a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 770164.7209302
Subtracting 258 from 300 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 16:
If we divide 420 by 129, we get 3 and a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 770164.72093023
Subtract 387 from 420 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final outcome is 770164.72093023, with a leftover of 3.3e-08.
