Let's divide 40857000 by 487
We want to figure out the number of times 40857000 can be divided by 487.

On to step 1:
4 divided by 487 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 487

Going ahead to step 2:
When dividing 40 by 487, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 487

Let's proceed to step 3:
If we divide 408 by 487, we get 0 and a remainder of 408.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 408, we get 408.
Grab the next digit (5) from the dividend, add it to 408, then carry on: 4085 / 487

Step 4:
If we divide 4085 by 487, we get 8 and a remainder of 189.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 189 after subtracting 3896 from 4085.
Include the next digit (7) from the dividend after 189, then repeat: 1897 / 487

On to step 5:
487 goes into 1897 3 times with a remainder of 436.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
Subtracting 1461 from 1897 leaves us with 436.
Include the next digit (0) from the dividend after 436, then repeat: 4360 / 487

Advancing to step 6:
487 goes into 4360 8 times with a remainder of 464.
Put 8 as the next digit of the answer. 
Result so far: 838.0
Subtracting 3896 from 4360 leaves us with 464.
Grab the next digit (0) from the dividend, add it to 464, then carry on: 4640 / 487

Moving on to step 7:
4640 divided by 487 is 9 with a remainder of 257.
Put 9 as the next digit of the answer. 
Result so far: 8389.0
Deduct 4383 from 4640 and we're left with 257.
Bring next digit (0) of the dividend behind the 257 and repeat the process: 2570 / 487

Going ahead to step 8:
487 can be fit into 2570 5 times, resulting in a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 83895.0
Subtracting 2435 from 2570 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 9:
If we divide 1350 by 487, we get 2 and a remainder of 376.
Put 2 as the next digit of the answer. 
Result so far: 83895.2
The remainder is 376 after subtracting 974 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 10:
If we divide 3760 by 487, we get 7 and a remainder of 351.
Put 7 as the next digit of the answer. 
Result so far: 83895.27
Subtract 3409 from 3760 to get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Step 11:
If we divide 3510 by 487, we get 7 and a remainder of 101.
Put 7 as the next digit of the answer. 
Result so far: 83895.277
Deduct 3409 from 3510 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

The final result is 83895.277 with a remainder of 0.0101.
