Let's divide 15788665 by 280
Let's see how many times 280 fits into 15788665.

On to step 1:
The number 280 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 280

Step 2:
280 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 280

Let's proceed to step 3:
When dividing 157 by 280, we get 0 with a remainder of 157.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 157 after subtracting 0 from 157.
Grab the next digit (8) from the dividend, add it to 157, then carry on: 1578 / 280

Moving on to step 4:
280 can be fit into 1578 5 times, resulting in a remainder of 178.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 1400 away from 1578, we end up with 178.
Take the next digit (8) from the dividend and append it to 178, then repeat: 1788 / 280

Advancing to step 5:
280 goes into 1788 6 times with a remainder of 108.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
The remainder is 108 after subtracting 1680 from 1788.
Take the next digit (6) from the dividend and append it to 108, then repeat: 1086 / 280

Let's proceed to step 6:
If we divide 1086 by 280, we get 3 and a remainder of 246.
Record the quotient 3 as the next digit in the result. 
Result so far: 563.0
Subtracting 840 from 1086 leaves us with 246.
Take the next digit (6) from the dividend and append it to 246, then repeat: 2466 / 280

Step 7:
280 goes into 2466 8 times with a remainder of 226.
Write down 8 as next digit of the result. 
Result so far: 5638.0
If we subtract 2240 from 2466, we get 226.
Append the next digit (5) from the dividend to 226 and continue with: 2265 / 280

Moving on to step 8:
2265 divided by 280 is 8 with a remainder of 25.
The number 8 becomes the next digit in our result. 
Result so far: 56388.0
The remainder is 25 after subtracting 2240 from 2265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
250 divided by 280 is 0 with a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 56388.0
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 10:
The number 280 fits into 2500 8 times, leaving a remainder of 260.
Use 8 as the next digit of our solution. 
Result so far: 56388.08
Subtract 2240 from 2500 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 11:
2600 divided by 280 is 9 with a remainder of 80.
Write down 9 as next digit of the result. 
Result so far: 56388.089
Deduct 2520 from 2600 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.

Advancing to step 12:
280 can be fit into 800 2 times, resulting in a remainder of 240.
The number 2 becomes the next digit in our result. 
Result so far: 56388.0892
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.

Advancing to step 13:
The number 280 fits into 2400 8 times, leaving a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 56388.08928
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.

Moving on to step 14:
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: 56388.089285
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 15:
280 goes into 2000 7 times with a remainder of 40.
The next digit of our result is 7. 
Result so far: 56388.0892857
If we take 1960 away from 2000, we end up with 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 16:
If we divide 400 by 280, we get 1 and a remainder of 120.
Put 1 as the next digit of the answer. 
Result so far: 56388.08928571
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.

The final outcome is 56388.08928571, with a leftover of 1.2e-07.
