Let's divide 690712 by 45
Our goal is to divide 690712 by 45.

Step 1:
When dividing 6 by 45, we get 0 with 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

Moving on to step 2:
When dividing 69 by 45, we get 1 with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 45 from 69 leaves us with 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 45

Let's proceed to step 3:
When dividing 240 by 45, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 225 from 240 and we're left with 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 45

Moving on to step 4:
45 can be fit into 157 3 times, resulting in a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 153.0
The remainder is 22 after subtracting 135 from 157.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 45

Step 5:
221 divided by 45 is 4 with a remainder of 41.
The number 4 becomes the next digit in our result. 
Result so far: 1534.0
The remainder is 41 after subtracting 180 from 221.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 45

Going ahead to step 6:
45 goes into 412 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 15349.0
Deduct 405 from 412 and we're left 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.

Step 7:
When dividing 70 by 45, we get 1 with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 15349.1
Subtract 45 from 70 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
45 goes into 250 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 15349.15
If we take 225 away from 250, 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.

Going ahead to step 9:
If we divide 250 by 45, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 15349.155
If we take 225 away from 250, 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.

The final result is 15349.155 with a remainder of 0.0025.
