We're dividing 40988530 by 280 
We want to divide 40988530 by 280.

Going ahead 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
If we subtract 0 from 4, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 280

Advancing to step 2:
The number 280 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Bring next digit (9) of the dividend behind the 40 and repeat the process: 409 / 280

Going ahead to step 3:
409 divided by 280 is 1 with a remainder of 129.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 280 from 409 and we're left with 129.
Bring next digit (8) of the dividend behind the 129 and repeat the process: 1298 / 280

Moving on to step 4:
1298 divided by 280 is 4 with a remainder of 178.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 178 after subtracting 1120 from 1298.
Append the next digit (8) from the dividend to 178 and continue with: 1788 / 280

Advancing to step 5:
1788 divided by 280 is 6 with a remainder of 108.
Record the quotient 6 as the next digit in the result. 
Result so far: 146.0
Subtracting 1680 from 1788 leaves us with 108.
Include the next digit (5) from the dividend after 108, then repeat: 1085 / 280

On to step 6:
280 goes into 1085 3 times with a remainder of 245.
Use 3 as the next digit of our solution. 
Result so far: 1463.0
If we take 840 away from 1085, we end up with 245.
Append the next digit (3) from the dividend to 245 and continue with: 2453 / 280

Advancing to step 7:
If we divide 2453 by 280, we get 8 and a remainder of 213.
The next digit of our result is 8. 
Result so far: 14638.0
If we take 2240 away from 2453, we end up with 213.
Grab the next digit (0) from the dividend, add it to 213, then carry on: 2130 / 280

Advancing to step 8:
280 can be fit into 2130 7 times, resulting in a remainder of 170.
Record the quotient 7 as the next digit in the result. 
Result so far: 146387.0
The remainder is 170 after subtracting 1960 from 2130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 9:
If we divide 1700 by 280, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 146387.6
The remainder is 20 after subtracting 1680 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
200 divided by 280 is 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 146387.6
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 11:
When dividing 2000 by 280, we get 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 146387.607
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.

Step 12:
280 can be fit into 400 1 times, resulting in a remainder of 120.
Use 1 as the next digit of our solution. 
Result so far: 146387.6071
Subtracting 280 from 400 leaves us 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 13:
280 can be fit into 1200 4 times, resulting in a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 146387.60714
Subtract 1120 from 1200 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 14:
800 divided by 280 is 2 with a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 146387.607142
If we take 560 away from 800, we end up 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 15:
2400 divided by 280 is 8 with a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 146387.6071428
If we take 2240 away from 2400, we end up 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 16:
280 can be fit into 1600 5 times, resulting in a remainder of 200.
The next digit of our result is 5. 
Result so far: 146387.60714285
If we take 1400 away from 1600, we end up 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.

The final result is 146387.60714285 with a remainder of 2e-07.
