We divide 691456 by 45
We want to figure out the number of times 691456 can be divided by 45.

Advancing to step 1:
The number 45 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 45

Let's proceed to step 2:
69 divided by 45 is 1 with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 45 from 69, we get 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 45

Step 3:
If we divide 241 by 45, we get 5 and a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 16 after subtracting 225 from 241.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 45

Step 4:
45 can be fit into 164 3 times, resulting in a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 153.0
Subtract 135 from 164 to get 29.
Fetch the next digit (5) from the dividend, attach it to 29 and continue: 295 / 45

Going ahead to step 5:
295 divided by 45 is 6 with a remainder of 25.
Record the quotient 6 as the next digit in the result. 
Result so far: 1536.0
Subtracting 270 from 295 leaves us with 25.
Bring next digit (6) of the dividend behind the 25 and repeat the process: 256 / 45

Let's proceed to step 6:
45 can be fit into 256 5 times, resulting in a remainder of 31.
Put 5 as the next digit of the answer. 
Result so far: 15365.0
Subtract 225 from 256 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
310 divided by 45 is 6 with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 15365.6
If we subtract 270 from 310, we get 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 8:
When dividing 400 by 45, we get 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 15365.68
Subtracting 360 from 400 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.

Advancing to step 9:
If we divide 400 by 45, we get 8 and a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 15365.688
Deduct 360 from 400 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.

The final result is 15365.688 with a remainder of 0.004.
