18980728 ÷ 687 
We want to figure out the number of times 18980728 can be divided by 687.

On to step 1:
The number 687 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 687

Let's proceed to step 2:
If we divide 18 by 687, we get 0 and a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 687

On to step 3:
If we divide 189 by 687, we get 0 and a remainder of 189.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 189 after subtracting 0 from 189.
Include the next digit (8) from the dividend after 189, then repeat: 1898 / 687

Going ahead to step 4:
The number 687 fits into 1898 2 times, leaving a remainder of 524.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1374 away from 1898, we end up with 524.
Bring next digit (0) of the dividend behind the 524 and repeat the process: 5240 / 687

Going ahead to step 5:
The number 687 fits into 5240 7 times, leaving a remainder of 431.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtract 4809 from 5240 to get 431.
Include the next digit (7) from the dividend after 431, then repeat: 4317 / 687

Advancing to step 6:
4317 divided by 687 is 6 with a remainder of 195.
Write down 6 as next digit of the result. 
Result so far: 276.0
The remainder is 195 after subtracting 4122 from 4317.
Take the next digit (2) from the dividend and append it to 195, then repeat: 1952 / 687

On to step 7:
If we divide 1952 by 687, we get 2 and a remainder of 578.
Put 2 as the next digit of the answer. 
Result so far: 2762.0
Deduct 1374 from 1952 and we're left with 578.
Fetch the next digit (8) from the dividend, attach it to 578 and continue: 5788 / 687

Advancing to step 8:
When dividing 5788 by 687, we get 8 with a remainder of 292.
Put 8 as the next digit of the answer. 
Result so far: 27628.0
Deduct 5496 from 5788 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 9:
The number 687 fits into 2920 4 times, leaving a remainder of 172.
The next digit of our result is 4. 
Result so far: 27628.4
Deduct 2748 from 2920 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 10:
1720 divided by 687 is 2 with a remainder of 346.
Use 2 as the next digit of our solution. 
Result so far: 27628.42
Subtract 1374 from 1720 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

On to step 11:
687 goes into 3460 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 27628.425
If we take 3435 away from 3460, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 12:
If we divide 250 by 687, we get 0 and a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 27628.425
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 13:
If we divide 2500 by 687, we get 3 and a remainder of 439.
Write down 3 as next digit of the result. 
Result so far: 27628.42503
The remainder is 439 after subtracting 2061 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Advancing to step 14:
687 can be fit into 4390 6 times, resulting in a remainder of 268.
Write down 6 as next digit of the result. 
Result so far: 27628.425036
If we subtract 4122 from 4390, we get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 15:
If we divide 2680 by 687, we get 3 and a remainder of 619.
Put 3 as the next digit of the answer. 
Result so far: 27628.4250363
The remainder is 619 after subtracting 2061 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Going ahead to step 16:
687 goes into 6190 9 times with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 27628.42503639
If we take 6183 away from 6190, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 27628.42503639 with a remaining 7e-09.
