We look at the division of 99712249 by 829 
Let's see how many times 829 fits into 99712249.

Step 1:
If we divide 9 by 829, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 829

Advancing to step 2:
When dividing 99 by 829, we get 0 with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Append the next digit (7) from the dividend to 99 and continue with: 997 / 829

On to step 3:
829 goes into 997 1 times with a remainder of 168.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 829 from 997 to get 168.
Bring next digit (1) of the dividend behind the 168 and repeat the process: 1681 / 829

Going ahead to step 4:
When dividing 1681 by 829, we get 2 with a remainder of 23.
The next digit of our result is 2. 
Result so far: 12.0
If we take 1658 away from 1681, we end up with 23.
Grab the next digit (2) from the dividend, add it to 23, then carry on: 232 / 829

On to step 5:
829 can be fit into 232 0 times, resulting in a remainder of 232.
Use 0 as the next digit of our solution. 
Result so far: 120.0
Deduct 0 from 232 and we're left with 232.
Take the next digit (2) from the dividend and append it to 232, then repeat: 2322 / 829

Moving on to step 6:
When dividing 2322 by 829, we get 2 with a remainder of 664.
Use 2 as the next digit of our solution. 
Result so far: 1202.0
Subtract 1658 from 2322 to get 664.
Fetch the next digit (4) from the dividend, attach it to 664 and continue: 6644 / 829

Step 7:
829 goes into 6644 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 12028.0
If we subtract 6632 from 6644, we get 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 829

Let's proceed to step 8:
129 divided by 829 is 0 with a remainder of 129.
Put 0 as the next digit of the answer. 
Result so far: 120280.0
Deduct 0 from 129 and we're left with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Let's proceed to step 9:
829 goes into 1290 1 times with a remainder of 461.
The next digit of our result is 1. 
Result so far: 120280.1
Deduct 829 from 1290 and we're left with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Advancing to step 10:
The number 829 fits into 4610 5 times, leaving a remainder of 465.
Record the quotient 5 as the next digit in the result. 
Result so far: 120280.15
Subtracting 4145 from 4610 leaves us with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Going ahead to step 11:
829 can be fit into 4650 5 times, resulting in a remainder of 505.
Put 5 as the next digit of the answer. 
Result so far: 120280.155
If we take 4145 away from 4650, we end up with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

The quotient of the division is 120280.155, and the remainder is 0.0505.
