Let's divide 45730857 by 280
We're looking to find how many times 280 goes into 45730857.

Moving on to step 1:
If we divide 4 by 280, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 280

Step 2:
280 goes into 45 0 times with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Append the next digit (7) from the dividend to 45 and continue with: 457 / 280

Let's proceed to step 3:
If we divide 457 by 280, we get 1 and a remainder of 177.
The next digit of our result is 1. 
Result so far: 1.0
If we take 280 away from 457, we end up with 177.
Grab the next digit (3) from the dividend, add it to 177, then carry on: 1773 / 280

Moving on to step 4:
If we divide 1773 by 280, we get 6 and a remainder of 93.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 1680 from 1773 leaves us with 93.
Grab the next digit (0) from the dividend, add it to 93, then carry on: 930 / 280

On to step 5:
280 can be fit into 930 3 times, resulting in a remainder of 90.
Record the quotient 3 as the next digit in the result. 
Result so far: 163.0
If we subtract 840 from 930, we get 90.
Grab the next digit (8) from the dividend, add it to 90, then carry on: 908 / 280

On to step 6:
908 divided by 280 is 3 with a remainder of 68.
Record the quotient 3 as the next digit in the result. 
Result so far: 1633.0
Subtract 840 from 908 to get 68.
Grab the next digit (5) from the dividend, add it to 68, then carry on: 685 / 280

Advancing to step 7:
If we divide 685 by 280, we get 2 and a remainder of 125.
The number 2 becomes the next digit in our result. 
Result so far: 16332.0
If we subtract 560 from 685, we get 125.
Include the next digit (7) from the dividend after 125, then repeat: 1257 / 280

Going ahead to step 8:
1257 divided by 280 is 4 with a remainder of 137.
The next digit of our result is 4. 
Result so far: 163324.0
If we subtract 1120 from 1257, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Going ahead to step 9:
1370 divided by 280 is 4 with a remainder of 250.
The next digit of our result is 4. 
Result so far: 163324.4
If we subtract 1120 from 1370, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 10:
280 can be fit into 2500 8 times, resulting in a remainder of 260.
The number 8 becomes the next digit in our result. 
Result so far: 163324.48
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.

Going ahead to step 11:
The number 280 fits into 2600 9 times, leaving a remainder of 80.
Write down 9 as next digit of the result. 
Result so far: 163324.489
Subtracting 2520 from 2600 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.

Advancing to step 12:
280 goes into 800 2 times with a remainder of 240.
Record the quotient 2 as the next digit in the result. 
Result so far: 163324.4892
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.

On to step 13:
The number 280 fits into 2400 8 times, leaving a remainder of 160.
Put 8 as the next digit of the answer. 
Result so far: 163324.48928
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:
1600 divided by 280 is 5 with a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 163324.489285
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.

Advancing to step 15:
If we divide 2000 by 280, we get 7 and a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 163324.4892857
Subtracting 1960 from 2000 leaves us 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.
The next digit of our result is 1. 
Result so far: 163324.48928571
If we subtract 280 from 400, we 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 result is 163324.48928571 with a remainder of 1.2e-07.
