We're dividing 436813 by 45 
We're looking to find how many times 45 goes into 436813.

Step 1:
45 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 45

On to step 2:
If we divide 43 by 45, we get 0 and a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Fetch the next digit (6) from the dividend, attach it to 43 and continue: 436 / 45

On to step 3:
When dividing 436 by 45, we get 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 405 from 436 to get 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 45

Advancing to step 4:
The number 45 fits into 318 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
If we subtract 315 from 318, we get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 45

Step 5:
When dividing 31 by 45, we get 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 970.0
Subtracting 0 from 31 leaves us with 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 45

Let's proceed to step 6:
If we divide 313 by 45, we get 6 and a remainder of 43.
The next digit of our result is 6. 
Result so far: 9706.0
Subtract 270 from 313 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
45 goes into 430 9 times with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 9706.9
Subtracting 405 from 430 leaves us 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.

On to step 8:
The number 45 fits into 250 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 9706.95
Subtract 225 from 250 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.

Going ahead to step 9:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 9706.955
Subtracting 225 from 250 leaves us 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 9706.955 with a remainder of 0.0025.
