Let's divide 39290726 by 280
Let's see how many times 280 fits into 39290726.

Step 1:
If we divide 3 by 280, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 280

Going ahead to step 2:
39 divided by 280 is 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Include the next digit (2) from the dividend after 39, then repeat: 392 / 280

Moving on to step 3:
If we divide 392 by 280, we get 1 and a remainder of 112.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 280 from 392 leaves us with 112.
Grab the next digit (9) from the dividend, add it to 112, then carry on: 1129 / 280

Going ahead to step 4:
The number 280 fits into 1129 4 times, leaving a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 9 after subtracting 1120 from 1129.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 280

Moving on to step 5:
When dividing 90 by 280, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 140.0
The remainder is 90 after subtracting 0 from 90.
Take the next digit (7) from the dividend and append it to 90, then repeat: 907 / 280

Step 6:
If we divide 907 by 280, we get 3 and a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 1403.0
If we take 840 away from 907, we end up with 67.
Fetch the next digit (2) from the dividend, attach it to 67 and continue: 672 / 280

Advancing to step 7:
672 divided by 280 is 2 with a remainder of 112.
The next digit of our result is 2. 
Result so far: 14032.0
If we subtract 560 from 672, we get 112.
Take the next digit (6) from the dividend and append it to 112, then repeat: 1126 / 280

Moving on to step 8:
280 can be fit into 1126 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 140324.0
If we take 1120 away from 1126, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
The number 280 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 140324.0
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
If we divide 600 by 280, we get 2 and a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 140324.02
Subtract 560 from 600 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.

Going ahead to step 11:
280 goes into 400 1 times with a remainder of 120.
Put 1 as the next digit of the answer. 
Result so far: 140324.021
Subtract 280 from 400 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.

Let's proceed to step 12:
280 goes into 1200 4 times with a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 140324.0214
Deduct 1120 from 1200 and we're left 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.

Let's proceed to step 13:
280 can be fit into 800 2 times, resulting in a remainder of 240.
Use 2 as the next digit of our solution. 
Result so far: 140324.02142
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.

On 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: 140324.021428
Deduct 2240 from 2400 and we're left 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.

Going ahead to step 15:
When dividing 1600 by 280, we get 5 with a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 140324.0214285
The remainder is 200 after subtracting 1400 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 16:
280 goes into 2000 7 times with a remainder of 40.
The next digit of our result is 7. 
Result so far: 140324.02142857
If we subtract 1960 from 2000, we 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.

Our division results in 140324.02142857 with a remaining 4e-08.
