We divide 63143251 by 285
The aim is to understand the frequency of 285 in 63143251.

Going ahead to step 1:
285 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 285

Moving on to step 2:
If we divide 63 by 285, we get 0 and a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Bring next digit (1) of the dividend behind the 63 and repeat the process: 631 / 285

Let's proceed to step 3:
The number 285 fits into 631 2 times, leaving a remainder of 61.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 570 from 631 to get 61.
Grab the next digit (4) from the dividend, add it to 61, then carry on: 614 / 285

Moving on to step 4:
If we divide 614 by 285, we get 2 and a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Deduct 570 from 614 and we're left with 44.
Bring next digit (3) of the dividend behind the 44 and repeat the process: 443 / 285

Advancing to step 5:
443 divided by 285 is 1 with a remainder of 158.
Use 1 as the next digit of our solution. 
Result so far: 221.0
If we take 285 away from 443, we end up with 158.
Fetch the next digit (2) from the dividend, attach it to 158 and continue: 1582 / 285

On to step 6:
285 goes into 1582 5 times with a remainder of 157.
Record the quotient 5 as the next digit in the result. 
Result so far: 2215.0
The remainder is 157 after subtracting 1425 from 1582.
Append the next digit (5) from the dividend to 157 and continue with: 1575 / 285

Going ahead to step 7:
1575 divided by 285 is 5 with a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 22155.0
If we subtract 1425 from 1575, we get 150.
Bring next digit (1) of the dividend behind the 150 and repeat the process: 1501 / 285

Going ahead to step 8:
285 goes into 1501 5 times with a remainder of 76.
Use 5 as the next digit of our solution. 
Result so far: 221555.0
Subtracting 1425 from 1501 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 9:
If we divide 760 by 285, we get 2 and a remainder of 190.
The number 2 becomes the next digit in our result. 
Result so far: 221555.2
Subtract 570 from 760 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 10:
If we divide 1900 by 285, we get 6 and a remainder of 190.
Record the quotient 6 as the next digit in the result. 
Result so far: 221555.26
The remainder is 190 after subtracting 1710 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 11:
285 goes into 1900 6 times with a remainder of 190.
Record the quotient 6 as the next digit in the result. 
Result so far: 221555.266
The remainder is 190 after subtracting 1710 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The quotient of the division is 221555.266, and the remainder is 0.019.
