We look at the division of 691357 by 45 
Our goal is to divide 691357 by 45.

Let's proceed to step 1:
The number 45 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 45

Moving on to step 2:
If we divide 69 by 45, we get 1 and a remainder of 24.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 45 from 69 to get 24.
Take the next digit (1) from the dividend and append it to 24, then repeat: 241 / 45

Let's proceed to step 3:
45 can be fit into 241 5 times, resulting in a remainder of 16.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 225 from 241 and we're left with 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 45

Step 4:
When dividing 163 by 45, we get 3 with a remainder of 28.
Use 3 as the next digit of our solution. 
Result so far: 153.0
If we take 135 away from 163, we end up with 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 45

Step 5:
45 goes into 285 6 times with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 1536.0
The remainder is 15 after subtracting 270 from 285.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 45

Moving on to step 6:
When dividing 157 by 45, we get 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 15363.0
Subtract 135 from 157 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
The number 45 fits into 220 4 times, leaving a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 15363.4
If we subtract 180 from 220, 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.

Moving on to step 8:
45 can be fit into 400 8 times, resulting in a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 15363.48
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.

Let's proceed to step 9:
45 can be fit into 400 8 times, resulting in a remainder of 40.
The next digit of our result is 8. 
Result so far: 15363.488
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.

The final result is 15363.488 with a remainder of 0.004.
