We look at the division of 21850245 by 285 
We're looking to find how many times 285 goes into 21850245.

On to step 1:
2 divided by 285 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 285

Let's proceed to step 2:
285 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 285

Step 3:
285 can be fit into 218 0 times, resulting in a remainder of 218.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 218 and we're left with 218.
Bring next digit (5) of the dividend behind the 218 and repeat the process: 2185 / 285

Step 4:
When dividing 2185 by 285, we get 7 with a remainder of 190.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 1995 from 2185 and we're left with 190.
Take the next digit (0) from the dividend and append it to 190, then repeat: 1900 / 285

Advancing to step 5:
1900 divided by 285 is 6 with a remainder of 190.
Put 6 as the next digit of the answer. 
Result so far: 76.0
If we take 1710 away from 1900, we end up with 190.
Include the next digit (2) from the dividend after 190, then repeat: 1902 / 285

Advancing to step 6:
The number 285 fits into 1902 6 times, leaving a remainder of 192.
Record the quotient 6 as the next digit in the result. 
Result so far: 766.0
Subtract 1710 from 1902 to get 192.
Include the next digit (4) from the dividend after 192, then repeat: 1924 / 285

On to step 7:
285 goes into 1924 6 times with a remainder of 214.
Use 6 as the next digit of our solution. 
Result so far: 7666.0
If we take 1710 away from 1924, we end up with 214.
Include the next digit (5) from the dividend after 214, then repeat: 2145 / 285

Going ahead to step 8:
When dividing 2145 by 285, we get 7 with a remainder of 150.
Write down 7 as next digit of the result. 
Result so far: 76667.0
The remainder is 150 after subtracting 1995 from 2145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 9:
1500 divided by 285 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 76667.5
If we subtract 1425 from 1500, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 10:
If we divide 750 by 285, we get 2 and a remainder of 180.
The number 2 becomes the next digit in our result. 
Result so far: 76667.52
Subtracting 570 from 750 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
285 can be fit into 1800 6 times, resulting in a remainder of 90.
The number 6 becomes the next digit in our result. 
Result so far: 76667.526
Deduct 1710 from 1800 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 12:
If we divide 900 by 285, we get 3 and a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 76667.5263
Deduct 855 from 900 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 13:
If we divide 450 by 285, we get 1 and a remainder of 165.
Write down 1 as next digit of the result. 
Result so far: 76667.52631
If we subtract 285 from 450, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 14:
285 goes into 1650 5 times with a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 76667.526315
If we take 1425 away from 1650, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 15:
When dividing 2250 by 285, we get 7 with a remainder of 255.
Use 7 as the next digit of our solution. 
Result so far: 76667.5263157
Subtracting 1995 from 2250 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Advancing to step 16:
2550 divided by 285 is 8 with a remainder of 270.
Record the quotient 8 as the next digit in the result. 
Result so far: 76667.52631578
If we subtract 2280 from 2550, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

The quotient of the division is 76667.52631578, and the remainder is 2.7e-07.
