Let's divide 843570 by 45
Our goal is to divide 843570 by 45.

Advancing to step 1:
45 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 45

Going ahead to step 2:
84 divided by 45 is 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 45 from 84 to get 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 45

Going ahead to step 3:
If we divide 393 by 45, we get 8 and a remainder of 33.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 360 from 393 and we're left with 33.
Bring next digit (5) of the dividend behind the 33 and repeat the process: 335 / 45

Going ahead to step 4:
45 goes into 335 7 times with a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 187.0
If we subtract 315 from 335, we get 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 45

Advancing to step 5:
45 can be fit into 207 4 times, resulting in a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 1874.0
Subtracting 180 from 207 leaves us with 27.
Fetch the next digit (0) from the dividend, attach it to 27 and continue: 270 / 45

Moving on to step 6:
The number 45 fits into 270 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 18746.0
If we take 270 away from 270, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
When dividing 0 by 45, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 18746.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
45 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18746.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 18746.0 with a remainder of 0.0.
