99712962 ÷ 280 
We want to figure out the number of times 99712962 can be divided by 280.

Let's proceed to step 1:
The number 280 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 280

Going ahead to step 2:
99 divided by 280 is 0 with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Include the next digit (7) from the dividend after 99, then repeat: 997 / 280

Step 3:
280 can be fit into 997 3 times, resulting in a remainder of 157.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 840 from 997 leaves us with 157.
Take the next digit (1) from the dividend and append it to 157, then repeat: 1571 / 280

Step 4:
When dividing 1571 by 280, we get 5 with a remainder of 171.
The next digit of our result is 5. 
Result so far: 35.0
The remainder is 171 after subtracting 1400 from 1571.
Include the next digit (2) from the dividend after 171, then repeat: 1712 / 280

Going ahead to step 5:
When dividing 1712 by 280, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 356.0
If we take 1680 away from 1712, we end up with 32.
Bring next digit (9) of the dividend behind the 32 and repeat the process: 329 / 280

Moving on to step 6:
280 goes into 329 1 times with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 3561.0
Deduct 280 from 329 and we're left with 49.
Bring next digit (6) of the dividend behind the 49 and repeat the process: 496 / 280

Going ahead to step 7:
If we divide 496 by 280, we get 1 and a remainder of 216.
The next digit of our result is 1. 
Result so far: 35611.0
Deduct 280 from 496 and we're left with 216.
Fetch the next digit (2) from the dividend, attach it to 216 and continue: 2162 / 280

Step 8:
When dividing 2162 by 280, we get 7 with a remainder of 202.
Write down 7 as next digit of the result. 
Result so far: 356117.0
Subtract 1960 from 2162 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 9:
280 goes into 2020 7 times with a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 356117.7
The remainder is 60 after subtracting 1960 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
When dividing 600 by 280, we get 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 356117.72
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
280 goes into 400 1 times with a remainder of 120.
Use 1 as the next digit of our solution. 
Result so far: 356117.721
If we take 280 away from 400, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 12:
280 can be fit into 1200 4 times, resulting in a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 356117.7214
If we take 1120 away from 1200, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
When dividing 800 by 280, we get 2 with a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 356117.72142
Deduct 560 from 800 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 14:
If we divide 2400 by 280, we get 8 and a remainder of 160.
Record the quotient 8 as the next digit in the result. 
Result so far: 356117.721428
Subtracting 2240 from 2400 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 15:
280 can be fit into 1600 5 times, resulting in a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 356117.7214285
If we subtract 1400 from 1600, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 16:
When dividing 2000 by 280, we get 7 with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 356117.72142857
Deduct 1960 from 2000 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 356117.72142857, and the remainder is 4e-08.
