We divide 369453 by 45
We want to figure out the number of times 369453 can be divided by 45.

Advancing to step 1:
45 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 45

Going ahead to step 2:
45 can be fit into 36 0 times, resulting in a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 36 to get 36.
Bring next digit (9) of the dividend behind the 36 and repeat the process: 369 / 45

Step 3:
When dividing 369 by 45, we get 8 with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 360 from 369 to get 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 45

Let's proceed to step 4:
The number 45 fits into 94 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 82.0
If we subtract 90 from 94, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 45

Moving on to step 5:
45 divided by 45 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 821.0
Subtract 45 from 45 to get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 45

Let's proceed to step 6:
45 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 8210.0
If we take 0 away from 3, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
45 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 8210.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
If we divide 300 by 45, we get 6 and a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 8210.06
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
When dividing 300 by 45, we get 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 8210.066
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 8210.066, with a leftover of 0.003.
