We divide 96643391 by 280
We want to figure out the number of times 96643391 can be divided by 280.

Advancing to step 1:
When dividing 9 by 280, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 280

Advancing to step 2:
If we divide 96 by 280, we get 0 and a remainder of 96.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 96, we end up with 96.
Append the next digit (6) from the dividend to 96 and continue with: 966 / 280

Moving on to step 3:
When dividing 966 by 280, we get 3 with a remainder of 126.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 840 from 966 to get 126.
Take the next digit (4) from the dividend and append it to 126, then repeat: 1264 / 280

Moving on to step 4:
280 goes into 1264 4 times with a remainder of 144.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Deduct 1120 from 1264 and we're left with 144.
Append the next digit (3) from the dividend to 144 and continue with: 1443 / 280

Let's proceed to step 5:
The number 280 fits into 1443 5 times, leaving a remainder of 43.
Use 5 as the next digit of our solution. 
Result so far: 345.0
If we take 1400 away from 1443, we end up with 43.
Include the next digit (3) from the dividend after 43, then repeat: 433 / 280

Advancing to step 6:
280 goes into 433 1 times with a remainder of 153.
The number 1 becomes the next digit in our result. 
Result so far: 3451.0
If we take 280 away from 433, we end up with 153.
Bring next digit (9) of the dividend behind the 153 and repeat the process: 1539 / 280

Advancing to step 7:
When dividing 1539 by 280, we get 5 with a remainder of 139.
Write down 5 as next digit of the result. 
Result so far: 34515.0
Deduct 1400 from 1539 and we're left with 139.
Bring next digit (1) of the dividend behind the 139 and repeat the process: 1391 / 280

On to step 8:
280 can be fit into 1391 4 times, resulting in a remainder of 271.
Use 4 as the next digit of our solution. 
Result so far: 345154.0
If we subtract 1120 from 1391, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Moving on to step 9:
280 goes into 2710 9 times with a remainder of 190.
The number 9 becomes the next digit in our result. 
Result so far: 345154.9
The remainder is 190 after subtracting 2520 from 2710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 10:
280 can be fit into 1900 6 times, resulting in a remainder of 220.
The number 6 becomes the next digit in our result. 
Result so far: 345154.96
If we take 1680 away from 1900, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 11:
If we divide 2200 by 280, we get 7 and a remainder of 240.
Put 7 as the next digit of the answer. 
Result so far: 345154.967
If we subtract 1960 from 2200, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 12:
When dividing 2400 by 280, we get 8 with a remainder of 160.
Put 8 as the next digit of the answer. 
Result so far: 345154.9678
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:
280 goes into 1600 5 times with a remainder of 200.
The next digit of our result is 5. 
Result so far: 345154.96785
Subtract 1400 from 1600 to 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.

Step 14:
280 goes into 2000 7 times with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 345154.967857
Subtract 1960 from 2000 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 15:
280 can be fit into 400 1 times, resulting in a remainder of 120.
Use 1 as the next digit of our solution. 
Result so far: 345154.9678571
If we subtract 280 from 400, we 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 16:
The number 280 fits into 1200 4 times, leaving a remainder of 80.
The next digit of our result is 4. 
Result so far: 345154.96785714
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.

After the division, we end up with 345154.96785714 and a remainder of 8e-08.
