We're dividing 81456613 by 280 
We want to figure out the number of times 81456613 can be divided by 280.

Going ahead to step 1:
The number 280 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 280

Advancing to step 2:
280 goes into 81 0 times with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Bring next digit (4) of the dividend behind the 81 and repeat the process: 814 / 280

Step 3:
The number 280 fits into 814 2 times, leaving a remainder of 254.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 560 from 814 and we're left with 254.
Grab the next digit (5) from the dividend, add it to 254, then carry on: 2545 / 280

Let's proceed to step 4:
If we divide 2545 by 280, we get 9 and a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Deduct 2520 from 2545 and we're left with 25.
Append the next digit (6) from the dividend to 25 and continue with: 256 / 280

Let's proceed to step 5:
256 divided by 280 is 0 with a remainder of 256.
Write down 0 as next digit of the result. 
Result so far: 290.0
Subtracting 0 from 256 leaves us with 256.
Append the next digit (6) from the dividend to 256 and continue with: 2566 / 280

Step 6:
280 goes into 2566 9 times with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 2909.0
If we subtract 2520 from 2566, we get 46.
Grab the next digit (1) from the dividend, add it to 46, then carry on: 461 / 280

Going ahead to step 7:
If we divide 461 by 280, we get 1 and a remainder of 181.
Write down 1 as next digit of the result. 
Result so far: 29091.0
If we subtract 280 from 461, we get 181.
Take the next digit (3) from the dividend and append it to 181, then repeat: 1813 / 280

Advancing to step 8:
280 can be fit into 1813 6 times, resulting in a remainder of 133.
Use 6 as the next digit of our solution. 
Result so far: 290916.0
If we take 1680 away from 1813, we end up with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Moving on to step 9:
280 goes into 1330 4 times with a remainder of 210.
The next digit of our result is 4. 
Result so far: 290916.4
The remainder is 210 after subtracting 1120 from 1330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 10:
When dividing 2100 by 280, we get 7 with a remainder of 140.
Record the quotient 7 as the next digit in the result. 
Result so far: 290916.47
Subtracting 1960 from 2100 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 11:
280 goes into 1400 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 290916.475
Deduct 1400 from 1400 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
If we divide 0 by 280, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 290916.475
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
0 divided by 280 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 290916.475
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 290916.475 with a remaining 0.0.
