98798152 ÷ 280 
Our goal is to divide 98798152 by 280.

Step 1:
The number 280 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 280

On to step 2:
The number 280 fits into 98 0 times, leaving a remainder of 98.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Grab the next digit (7) from the dividend, add it to 98, then carry on: 987 / 280

On to step 3:
280 can be fit into 987 3 times, resulting in a remainder of 147.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 147 after subtracting 840 from 987.
Take the next digit (9) from the dividend and append it to 147, then repeat: 1479 / 280

Step 4:
The number 280 fits into 1479 5 times, leaving a remainder of 79.
Write down 5 as next digit of the result. 
Result so far: 35.0
Deduct 1400 from 1479 and we're left with 79.
Bring next digit (8) of the dividend behind the 79 and repeat the process: 798 / 280

Advancing to step 5:
798 divided by 280 is 2 with a remainder of 238.
Record the quotient 2 as the next digit in the result. 
Result so far: 352.0
If we subtract 560 from 798, we get 238.
Take the next digit (1) from the dividend and append it to 238, then repeat: 2381 / 280

Moving on to step 6:
When dividing 2381 by 280, we get 8 with a remainder of 141.
Put 8 as the next digit of the answer. 
Result so far: 3528.0
Subtracting 2240 from 2381 leaves us with 141.
Take the next digit (5) from the dividend and append it to 141, then repeat: 1415 / 280

Going ahead to step 7:
When dividing 1415 by 280, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 35285.0
If we subtract 1400 from 1415, we get 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 280

Going ahead to step 8:
When dividing 152 by 280, we get 0 with a remainder of 152.
Write down 0 as next digit of the result. 
Result so far: 352850.0
Deduct 0 from 152 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 9:
1520 divided by 280 is 5 with a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 352850.5
Subtracting 1400 from 1520 leaves us 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.

Step 10:
280 goes into 1200 4 times with a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 352850.54
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.

On to step 11:
If we divide 800 by 280, we get 2 and a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 352850.542
The remainder is 240 after subtracting 560 from 800.
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 12:
280 can be fit into 2400 8 times, resulting in a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 352850.5428
Subtract 2240 from 2400 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 13:
1600 divided by 280 is 5 with a remainder of 200.
The next digit of our result is 5. 
Result so far: 352850.54285
Subtracting 1400 from 1600 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 14:
280 goes into 2000 7 times with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 352850.542857
The remainder is 40 after subtracting 1960 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 15:
The number 280 fits into 400 1 times, leaving a remainder of 120.
Write down 1 as next digit of the result. 
Result so far: 352850.5428571
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.

Going ahead to step 16:
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: 352850.54285714
Subtracting 1120 from 1200 leaves us 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.

The final result is 352850.54285714 with a remainder of 8e-08.
