We look at the division of 77890689 by 280 
Let's see how many times 280 fits into 77890689.

On to step 1:
The number 280 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 280

Advancing to step 2:
The number 280 fits into 77 0 times, leaving a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Append the next digit (8) from the dividend to 77 and continue with: 778 / 280

Step 3:
280 can be fit into 778 2 times, resulting in a remainder of 218.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 218 after subtracting 560 from 778.
Grab the next digit (9) from the dividend, add it to 218, then carry on: 2189 / 280

Going ahead to step 4:
280 can be fit into 2189 7 times, resulting in a remainder of 229.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtracting 1960 from 2189 leaves us with 229.
Fetch the next digit (0) from the dividend, attach it to 229 and continue: 2290 / 280

Advancing to step 5:
280 can be fit into 2290 8 times, resulting in a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 278.0
The remainder is 50 after subtracting 2240 from 2290.
Grab the next digit (6) from the dividend, add it to 50, then carry on: 506 / 280

Going ahead to step 6:
If we divide 506 by 280, we get 1 and a remainder of 226.
Write down 1 as next digit of the result. 
Result so far: 2781.0
The remainder is 226 after subtracting 280 from 506.
Include the next digit (8) from the dividend after 226, then repeat: 2268 / 280

Step 7:
The number 280 fits into 2268 8 times, leaving a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 27818.0
Subtracting 2240 from 2268 leaves us with 28.
Include the next digit (9) from the dividend after 28, then repeat: 289 / 280

On to step 8:
280 goes into 289 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 278181.0
If we subtract 280 from 289, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
280 can be fit into 90 0 times, resulting in a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 278181.0
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
280 goes into 900 3 times with a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 278181.03
The remainder is 60 after subtracting 840 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
If we divide 600 by 280, we get 2 and a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 278181.032
Deduct 560 from 600 and we're left 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 12:
400 divided by 280 is 1 with a remainder of 120.
The next digit of our result is 1. 
Result so far: 278181.0321
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.

Let's proceed to step 13:
When dividing 1200 by 280, we get 4 with a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 278181.03214
The remainder is 80 after subtracting 1120 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 14:
If we divide 800 by 280, we get 2 and a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 278181.032142
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.

Advancing to step 15:
When dividing 2400 by 280, we get 8 with a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 278181.0321428
Subtracting 2240 from 2400 leaves us 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.

Step 16:
The number 280 fits into 1600 5 times, leaving a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 278181.03214285
Deduct 1400 from 1600 and we're left 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.

After the division, we end up with 278181.03214285 and a remainder of 2e-07.
