We're dividing 12857237 by 445 
We want to figure out the number of times 12857237 can be divided by 445.

Step 1:
1 divided by 445 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 445

Step 2:
445 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 445

On to step 3:
If we divide 128 by 445, we get 0 and a remainder of 128.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 128 to get 128.
Grab the next digit (5) from the dividend, add it to 128, then carry on: 1285 / 445

Let's proceed to step 4:
1285 divided by 445 is 2 with a remainder of 395.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 890 from 1285 and we're left with 395.
Include the next digit (7) from the dividend after 395, then repeat: 3957 / 445

On to step 5:
3957 divided by 445 is 8 with a remainder of 397.
Use 8 as the next digit of our solution. 
Result so far: 28.0
The remainder is 397 after subtracting 3560 from 3957.
Bring next digit (2) of the dividend behind the 397 and repeat the process: 3972 / 445

On to step 6:
If we divide 3972 by 445, we get 8 and a remainder of 412.
Put 8 as the next digit of the answer. 
Result so far: 288.0
Deduct 3560 from 3972 and we're left with 412.
Grab the next digit (3) from the dividend, add it to 412, then carry on: 4123 / 445

On to step 7:
445 goes into 4123 9 times with a remainder of 118.
The number 9 becomes the next digit in our result. 
Result so far: 2889.0
Subtract 4005 from 4123 to get 118.
Grab the next digit (7) from the dividend, add it to 118, then carry on: 1187 / 445

Step 8:
The number 445 fits into 1187 2 times, leaving a remainder of 297.
The next digit of our result is 2. 
Result so far: 28892.0
Deduct 890 from 1187 and we're left with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Let's proceed to step 9:
If we divide 2970 by 445, we get 6 and a remainder of 300.
Put 6 as the next digit of the answer. 
Result so far: 28892.6
If we subtract 2670 from 2970, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 10:
If we divide 3000 by 445, we get 6 and a remainder of 330.
The next digit of our result is 6. 
Result so far: 28892.66
If we subtract 2670 from 3000, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

The final outcome is 28892.66, with a leftover of 0.33.
