Let's divide 84129275 by 280
Our goal is to divide 84129275 by 280.

On to step 1:
8 divided by 280 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 280

Step 2:
280 goes into 84 0 times with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Include the next digit (1) from the dividend after 84, then repeat: 841 / 280

Step 3:
When dividing 841 by 280, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 840 from 841, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 280

Moving on to step 4:
If we divide 12 by 280, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtract 0 from 12 to get 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 280

Let's proceed to step 5:
When dividing 129 by 280, we get 0 with a remainder of 129.
The next digit of our result is 0. 
Result so far: 300.0
Subtracting 0 from 129 leaves us with 129.
Bring next digit (2) of the dividend behind the 129 and repeat the process: 1292 / 280

Let's proceed to step 6:
1292 divided by 280 is 4 with a remainder of 172.
The next digit of our result is 4. 
Result so far: 3004.0
If we take 1120 away from 1292, we end up with 172.
Append the next digit (7) from the dividend to 172 and continue with: 1727 / 280

On to step 7:
1727 divided by 280 is 6 with a remainder of 47.
Use 6 as the next digit of our solution. 
Result so far: 30046.0
Subtract 1680 from 1727 to get 47.
Grab the next digit (5) from the dividend, add it to 47, then carry on: 475 / 280

Moving on to step 8:
280 can be fit into 475 1 times, resulting in a remainder of 195.
Record the quotient 1 as the next digit in the result. 
Result so far: 300461.0
Subtracting 280 from 475 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Going ahead to step 9:
280 can be fit into 1950 6 times, resulting in a remainder of 270.
Write down 6 as next digit of the result. 
Result so far: 300461.6
If we take 1680 away from 1950, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 10:
280 goes into 2700 9 times with a remainder of 180.
Put 9 as the next digit of the answer. 
Result so far: 300461.69
If we subtract 2520 from 2700, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
The number 280 fits into 1800 6 times, leaving a remainder of 120.
Write down 6 as next digit of the result. 
Result so far: 300461.696
Subtract 1680 from 1800 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.

Moving on to step 12:
280 can be fit into 1200 4 times, resulting in a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 300461.6964
If we subtract 1120 from 1200, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
280 can be fit into 800 2 times, resulting in a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 300461.69642
Subtracting 560 from 800 leaves us 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.

Advancing to step 14:
2400 divided by 280 is 8 with a remainder of 160.
Record the quotient 8 as the next digit in the result. 
Result so far: 300461.696428
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.

Moving on to step 15:
1600 divided by 280 is 5 with a remainder of 200.
The next digit of our result is 5. 
Result so far: 300461.6964285
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.

Let's proceed to step 16:
280 can be fit into 2000 7 times, resulting in a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 300461.69642857
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.

The final result is 300461.69642857 with a remainder of 4e-08.
