70413638 ÷ 280 
We want to divide 70413638 by 280.

Moving on to step 1:
If we divide 7 by 280, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 280

Let's proceed to step 2:
280 goes into 70 0 times with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Include the next digit (4) from the dividend after 70, then repeat: 704 / 280

Going ahead to step 3:
When dividing 704 by 280, we get 2 with a remainder of 144.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 560 from 704 to get 144.
Fetch the next digit (1) from the dividend, attach it to 144 and continue: 1441 / 280

Moving on to step 4:
1441 divided by 280 is 5 with a remainder of 41.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtracting 1400 from 1441 leaves us with 41.
Grab the next digit (3) from the dividend, add it to 41, then carry on: 413 / 280

Going ahead to step 5:
When dividing 413 by 280, we get 1 with a remainder of 133.
Write down 1 as next digit of the result. 
Result so far: 251.0
If we take 280 away from 413, we end up with 133.
Bring next digit (6) of the dividend behind the 133 and repeat the process: 1336 / 280

Advancing to step 6:
1336 divided by 280 is 4 with a remainder of 216.
Write down 4 as next digit of the result. 
Result so far: 2514.0
If we take 1120 away from 1336, we end up with 216.
Fetch the next digit (3) from the dividend, attach it to 216 and continue: 2163 / 280

Going ahead to step 7:
When dividing 2163 by 280, we get 7 with a remainder of 203.
The number 7 becomes the next digit in our result. 
Result so far: 25147.0
If we subtract 1960 from 2163, we get 203.
Grab the next digit (8) from the dividend, add it to 203, then carry on: 2038 / 280

Let's proceed to step 8:
280 goes into 2038 7 times with a remainder of 78.
The next digit of our result is 7. 
Result so far: 251477.0
If we subtract 1960 from 2038, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 9:
The number 280 fits into 780 2 times, leaving a remainder of 220.
Write down 2 as next digit of the result. 
Result so far: 251477.2
The remainder is 220 after subtracting 560 from 780.
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 10:
2200 divided by 280 is 7 with a remainder of 240.
Record the quotient 7 as the next digit in the result. 
Result so far: 251477.27
The remainder is 240 after subtracting 1960 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 11:
2400 divided by 280 is 8 with a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 251477.278
The remainder is 160 after subtracting 2240 from 2400.
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 12:
The number 280 fits into 1600 5 times, leaving a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 251477.2785
Deduct 1400 from 1600 and we're left 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 13:
The number 280 fits into 2000 7 times, leaving a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 251477.27857
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.

Moving on to step 14:
If we divide 400 by 280, we get 1 and a remainder of 120.
Use 1 as the next digit of our solution. 
Result so far: 251477.278571
Deduct 280 from 400 and we're left 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 15:
280 goes into 1200 4 times with a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 251477.2785714
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.

Step 16:
280 can be fit into 800 2 times, resulting in a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 251477.27857142
If we subtract 560 from 800, 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.

After the division, we end up with 251477.27857142 and a remainder of 2.4e-07.
