We're dividing 3538522 by 45 
We're looking to find how many times 45 goes into 3538522.

Step 1:
45 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 45

Moving on to step 2:
If we divide 35 by 45, we get 0 and a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 45

Going ahead to step 3:
If we divide 353 by 45, we get 7 and a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 315 away from 353, we end up with 38.
Bring next digit (8) of the dividend behind the 38 and repeat the process: 388 / 45

On to step 4:
When dividing 388 by 45, we get 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtracting 360 from 388 leaves us with 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 45

Let's proceed to step 5:
When dividing 285 by 45, we get 6 with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 786.0
If we subtract 270 from 285, we get 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 45

Moving on to step 6:
152 divided by 45 is 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 7863.0
Subtract 135 from 152 to get 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 45

Moving on to step 7:
45 can be fit into 172 3 times, resulting in a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 78633.0
If we take 135 away from 172, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 8:
45 goes into 370 8 times with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 78633.8
If we take 360 away from 370, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
When dividing 100 by 45, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 78633.82
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
If we divide 100 by 45, we get 2 and a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 78633.822
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 78633.822 and a remainder of 0.001.
