45369785 ÷ 45 
Let's see how many times 45 fits into 45369785.

Advancing to step 1:
45 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 45

Step 2:
45 goes into 45 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we take 45 away from 45, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 45

Moving on to step 3:
When dividing 3 by 45, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 3, we end up with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 45

Advancing to step 4:
The number 45 fits into 36 0 times, leaving a remainder of 36.
The next digit of our result is 0. 
Result so far: 100.0
If we subtract 0 from 36, we get 36.
Grab the next digit (9) from the dividend, add it to 36, then carry on: 369 / 45

Moving on to step 5:
45 can be fit into 369 8 times, resulting in a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 1008.0
If we subtract 360 from 369, we get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 45

Advancing to step 6:
45 can be fit into 97 2 times, resulting in a remainder of 7.
The next digit of our result is 2. 
Result so far: 10082.0
If we take 90 away from 97, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 45

Let's proceed to step 7:
If we divide 78 by 45, we get 1 and a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 100821.0
If we subtract 45 from 78, we get 33.
Take the next digit (5) from the dividend and append it to 33, then repeat: 335 / 45

Moving on to step 8:
335 divided by 45 is 7 with a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 1008217.0
If we subtract 315 from 335, we 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.

Let's proceed to step 9:
45 can be fit into 200 4 times, resulting in a remainder of 20.
The next digit of our result is 4. 
Result so far: 1008217.4
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 10:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 1008217.44
Deduct 180 from 200 and we're left 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.

In conclusion, the division gives 1008217.44 with a balance of 0.02.
