43669821 ÷ 285 
Our goal is to divide 43669821 by 285.

Moving on to step 1:
The number 285 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 285

Advancing to step 2:
The number 285 fits into 43 0 times, leaving a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Take the next digit (6) from the dividend and append it to 43, then repeat: 436 / 285

Moving on to step 3:
When dividing 436 by 285, we get 1 with a remainder of 151.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 285 away from 436, we end up with 151.
Grab the next digit (6) from the dividend, add it to 151, then carry on: 1516 / 285

Step 4:
285 can be fit into 1516 5 times, resulting in a remainder of 91.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 1425 from 1516 leaves us with 91.
Take the next digit (9) from the dividend and append it to 91, then repeat: 919 / 285

On to step 5:
The number 285 fits into 919 3 times, leaving a remainder of 64.
The next digit of our result is 3. 
Result so far: 153.0
If we take 855 away from 919, we end up with 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 285

Going ahead to step 6:
285 goes into 648 2 times with a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 1532.0
Subtracting 570 from 648 leaves us with 78.
Take the next digit (2) from the dividend and append it to 78, then repeat: 782 / 285

Step 7:
If we divide 782 by 285, we get 2 and a remainder of 212.
Use 2 as the next digit of our solution. 
Result so far: 15322.0
Deduct 570 from 782 and we're left with 212.
Grab the next digit (1) from the dividend, add it to 212, then carry on: 2121 / 285

On to step 8:
285 can be fit into 2121 7 times, resulting in a remainder of 126.
Write down 7 as next digit of the result. 
Result so far: 153227.0
If we subtract 1995 from 2121, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 9:
285 can be fit into 1260 4 times, resulting in a remainder of 120.
The next digit of our result is 4. 
Result so far: 153227.4
Subtract 1140 from 1260 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 10:
When dividing 1200 by 285, we get 4 with a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 153227.44
Deduct 1140 from 1200 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 153227.44, with a leftover of 0.06.
