73872054 ÷ 280 
We want to figure out the number of times 73872054 can be divided by 280.

Let's proceed to step 1:
280 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 280

Step 2:
73 divided by 280 is 0 with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Include the next digit (8) from the dividend after 73, then repeat: 738 / 280

On to step 3:
The number 280 fits into 738 2 times, leaving a remainder of 178.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 178 after subtracting 560 from 738.
Grab the next digit (7) from the dividend, add it to 178, then carry on: 1787 / 280

Advancing to step 4:
If we divide 1787 by 280, we get 6 and a remainder of 107.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we subtract 1680 from 1787, we get 107.
Grab the next digit (2) from the dividend, add it to 107, then carry on: 1072 / 280

Advancing to step 5:
When dividing 1072 by 280, we get 3 with a remainder of 232.
Use 3 as the next digit of our solution. 
Result so far: 263.0
Subtract 840 from 1072 to get 232.
Grab the next digit (0) from the dividend, add it to 232, then carry on: 2320 / 280

On to step 6:
2320 divided by 280 is 8 with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 2638.0
If we take 2240 away from 2320, we end up with 80.
Take the next digit (5) from the dividend and append it to 80, then repeat: 805 / 280

Advancing to step 7:
280 can be fit into 805 2 times, resulting in a remainder of 245.
Put 2 as the next digit of the answer. 
Result so far: 26382.0
If we subtract 560 from 805, we get 245.
Bring next digit (4) of the dividend behind the 245 and repeat the process: 2454 / 280

Step 8:
280 can be fit into 2454 8 times, resulting in a remainder of 214.
Use 8 as the next digit of our solution. 
Result so far: 263828.0
Subtracting 2240 from 2454 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 9:
When dividing 2140 by 280, we get 7 with a remainder of 180.
Use 7 as the next digit of our solution. 
Result so far: 263828.7
Subtracting 1960 from 2140 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 10:
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: 263828.76
If we take 1680 away from 1800, we end up 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.

Step 11:
1200 divided by 280 is 4 with a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 263828.764
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.

Let's proceed to step 12:
280 goes into 800 2 times with a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 263828.7642
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.

Moving on to step 13:
If we divide 2400 by 280, we get 8 and a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 263828.76428
If we subtract 2240 from 2400, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
280 can be fit into 1600 5 times, resulting in a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 263828.764285
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.

Going ahead to step 15:
If we divide 2000 by 280, we get 7 and a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 263828.7642857
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.

Let's proceed to step 16:
280 can be fit into 400 1 times, resulting in a remainder of 120.
Write down 1 as next digit of the result. 
Result so far: 263828.76428571
If we take 280 away from 400, we end up 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.

The final result is 263828.76428571 with a remainder of 1.2e-07.
