8158746 ÷ 280 
We want to figure out the number of times 8158746 can be divided by 280.

Going ahead to step 1:
8 divided by 280 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 280

Advancing to step 2:
When dividing 81 by 280, we get 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Bring next digit (5) of the dividend behind the 81 and repeat the process: 815 / 280

Let's proceed to step 3:
815 divided by 280 is 2 with a remainder of 255.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 560 from 815 to get 255.
Fetch the next digit (8) from the dividend, attach it to 255 and continue: 2558 / 280

Going ahead to step 4:
2558 divided by 280 is 9 with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 29.0
Subtracting 2520 from 2558 leaves us with 38.
Fetch the next digit (7) from the dividend, attach it to 38 and continue: 387 / 280

Step 5:
280 goes into 387 1 times with a remainder of 107.
Write down 1 as next digit of the result. 
Result so far: 291.0
If we subtract 280 from 387, we get 107.
Append the next digit (4) from the dividend to 107 and continue with: 1074 / 280

Let's proceed to step 6:
280 goes into 1074 3 times with a remainder of 234.
Record the quotient 3 as the next digit in the result. 
Result so far: 2913.0
The remainder is 234 after subtracting 840 from 1074.
Include the next digit (6) from the dividend after 234, then repeat: 2346 / 280

Moving on to step 7:
If we divide 2346 by 280, we get 8 and a remainder of 106.
Record the quotient 8 as the next digit in the result. 
Result so far: 29138.0
The remainder is 106 after subtracting 2240 from 2346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 8:
If we divide 1060 by 280, we get 3 and a remainder of 220.
Use 3 as the next digit of our solution. 
Result so far: 29138.3
If we take 840 away from 1060, 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.

Going ahead to step 9:
280 can be fit into 2200 7 times, resulting in a remainder of 240.
The next digit of our result is 7. 
Result so far: 29138.37
Deduct 1960 from 2200 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 10:
2400 divided by 280 is 8 with a remainder of 160.
Put 8 as the next digit of the answer. 
Result so far: 29138.378
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.

Advancing to step 11:
1600 divided by 280 is 5 with a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 29138.3785
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.

On to step 12:
When dividing 2000 by 280, we get 7 with a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 29138.37857
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.

Going ahead to step 13:
If we divide 400 by 280, we get 1 and a remainder of 120.
The number 1 becomes the next digit in our result. 
Result so far: 29138.378571
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.

Step 14:
If we divide 1200 by 280, we get 4 and a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 29138.3785714
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.

Going ahead to step 15:
280 can be fit into 800 2 times, resulting in a remainder of 240.
Record the quotient 2 as the next digit in the result. 
Result so far: 29138.37857142
Subtract 560 from 800 to 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 29138.37857142 and a remainder of 2.4e-07.
