Let's divide 63643111 by 285
The aim is to understand the frequency of 285 in 63643111.

Moving on to step 1:
When dividing 6 by 285, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 285

Going ahead to step 2:
285 can be fit into 63 0 times, resulting in a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Include the next digit (6) from the dividend after 63, then repeat: 636 / 285

On to step 3:
If we divide 636 by 285, we get 2 and a remainder of 66.
The next digit of our result is 2. 
Result so far: 2.0
If we take 570 away from 636, we end up with 66.
Grab the next digit (4) from the dividend, add it to 66, then carry on: 664 / 285

Step 4:
If we divide 664 by 285, we get 2 and a remainder of 94.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 570 from 664 to get 94.
Take the next digit (3) from the dividend and append it to 94, then repeat: 943 / 285

Moving on to step 5:
285 goes into 943 3 times with a remainder of 88.
Use 3 as the next digit of our solution. 
Result so far: 223.0
If we take 855 away from 943, we end up with 88.
Append the next digit (1) from the dividend to 88 and continue with: 881 / 285

Let's proceed to step 6:
285 goes into 881 3 times with a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 2233.0
If we take 855 away from 881, we end up with 26.
Take the next digit (1) from the dividend and append it to 26, then repeat: 261 / 285

Let's proceed to step 7:
When dividing 261 by 285, we get 0 with a remainder of 261.
The next digit of our result is 0. 
Result so far: 22330.0
The remainder is 261 after subtracting 0 from 261.
Fetch the next digit (1) from the dividend, attach it to 261 and continue: 2611 / 285

Step 8:
When dividing 2611 by 285, we get 9 with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 223309.0
Deduct 2565 from 2611 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
If we divide 460 by 285, we get 1 and a remainder of 175.
The number 1 becomes the next digit in our result. 
Result so far: 223309.1
The remainder is 175 after subtracting 285 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 10:
When dividing 1750 by 285, we get 6 with a remainder of 40.
The next digit of our result is 6. 
Result so far: 223309.16
Subtract 1710 from 1750 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
When dividing 400 by 285, we get 1 with a remainder of 115.
Use 1 as the next digit of our solution. 
Result so far: 223309.161
Deduct 285 from 400 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 12:
1150 divided by 285 is 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 223309.1614
If we take 1140 away from 1150, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
The number 285 fits into 100 0 times, leaving a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 223309.1614
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 14:
If we divide 1000 by 285, we get 3 and a remainder of 145.
Write down 3 as next digit of the result. 
Result so far: 223309.161403
Subtracting 855 from 1000 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 15:
When dividing 1450 by 285, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 223309.1614035
Deduct 1425 from 1450 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 16:
250 divided by 285 is 0 with a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 223309.1614035
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

After the division, we end up with 223309.1614035 and a remainder of 2.5e-07.
