We're dividing 691445 by 45 
Let's see how many times 45 fits into 691445.

Moving on to step 1:
When dividing 6 by 45, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 45

Let's proceed to step 2:
69 divided by 45 is 1 with a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 45 from 69 leaves us with 24.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 45

Advancing to step 3:
45 can be fit into 241 5 times, resulting in a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 225 from 241 leaves us with 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 45

Advancing to step 4:
When dividing 164 by 45, we get 3 with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 153.0
Subtracting 135 from 164 leaves us with 29.
Fetch the next digit (4) from the dividend, attach it to 29 and continue: 294 / 45

Going ahead to step 5:
If we divide 294 by 45, we get 6 and a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 1536.0
Subtract 270 from 294 to get 24.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 45

On to step 6:
When dividing 245 by 45, we get 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 15365.0
If we take 225 away from 245, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
The number 45 fits into 200 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 15365.4
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
45 can be fit into 200 4 times, resulting in a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 15365.44
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 15365.44 with a remaining 0.02.
