886456 ÷ 45 
Our goal is to divide 886456 by 45.

Going ahead to step 1:
The number 45 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 45

Step 2:
The number 45 fits into 88 1 times, leaving a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 45 from 88 to get 43.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 45

Advancing to step 3:
45 goes into 436 9 times with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 405 from 436 and we're left with 31.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 45

Going ahead to step 4:
45 goes into 314 6 times with a remainder of 44.
The next digit of our result is 6. 
Result so far: 196.0
Deduct 270 from 314 and we're left with 44.
Bring next digit (5) of the dividend behind the 44 and repeat the process: 445 / 45

Moving on to step 5:
If we divide 445 by 45, we get 9 and a remainder of 40.
The next digit of our result is 9. 
Result so far: 1969.0
Subtract 405 from 445 to get 40.
Grab the next digit (6) from the dividend, add it to 40, then carry on: 406 / 45

Let's proceed to step 6:
The number 45 fits into 406 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 19699.0
Deduct 405 from 406 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 45 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 19699.0
If we take 0 away from 10, 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.

Moving on to step 8:
45 goes into 100 2 times with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 19699.02
If we take 90 away from 100, 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:
45 can be fit into 100 2 times, resulting in a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 19699.022
Deduct 90 from 100 and we're left 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.

The final outcome is 19699.022, with a leftover of 0.001.
