We look at the division of 689103 by 1 
Let's see how many times 1 fits into 689103.

Let's proceed to step 1:
6 divided by 1 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 6 from 6 leaves us with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

On to step 2:
1 goes into 8 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
If we subtract 8 from 8, we get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Let's proceed to step 3:
When dividing 9 by 1, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 689.0
The remainder is 0 after subtracting 9 from 9.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Moving on to step 4:
When dividing 1 by 1, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 6891.0
The remainder is 0 after subtracting 1 from 1.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Moving on to step 5:
1 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 68910.0
Subtracting 0 from 0 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Moving on to step 6:
The number 1 fits into 3 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 689103.0
Deduct 3 from 3 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.

Step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 689103.0
Subtracting 0 from 0 leaves us 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.

On to step 8:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 689103.0
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.

After the division, we end up with 689103.0 and a remainder of 0.0.
