Let's divide 873837 by 45
We want to divide 873837 by 45.

Advancing to step 1:
45 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 45

Let's proceed to step 2:
45 can be fit into 87 1 times, resulting in a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 45 away from 87, we end up with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 45

Step 3:
When dividing 423 by 45, we get 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 405 from 423 to get 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 45

Advancing to step 4:
When dividing 188 by 45, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 194.0
Subtract 180 from 188 to get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 45

On to step 5:
If we divide 83 by 45, we get 1 and a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 1941.0
Deduct 45 from 83 and we're left with 38.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 45

Let's proceed to step 6:
45 goes into 387 8 times with a remainder of 27.
The next digit of our result is 8. 
Result so far: 19418.0
Subtract 360 from 387 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
270 divided by 45 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 19418.6
The remainder is 0 after subtracting 270 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
If we divide 0 by 45, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 19418.6
If we take 0 away from 0, 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.

On to step 9:
The number 45 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 19418.6
Subtract 0 from 0 to 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.

The final result is 19418.6 with a remainder of 0.0.
