63666560 divided by 246 
The aim is to understand the frequency of 246 in 63666560.

On to step 1:
6 divided by 246 is 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.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 246

Moving on to step 2:
63 divided by 246 is 0 with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Append the next digit (6) from the dividend to 63 and continue with: 636 / 246

Advancing to step 3:
The number 246 fits into 636 2 times, leaving a remainder of 144.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 144 after subtracting 492 from 636.
Take the next digit (6) from the dividend and append it to 144, then repeat: 1446 / 246

On to step 4:
246 goes into 1446 5 times with a remainder of 216.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 1230 from 1446 and we're left with 216.
Bring next digit (6) of the dividend behind the 216 and repeat the process: 2166 / 246

On to step 5:
246 can be fit into 2166 8 times, resulting in a remainder of 198.
The next digit of our result is 8. 
Result so far: 258.0
If we take 1968 away from 2166, we end up with 198.
Grab the next digit (5) from the dividend, add it to 198, then carry on: 1985 / 246

Let's proceed to step 6:
When dividing 1985 by 246, we get 8 with a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 2588.0
The remainder is 17 after subtracting 1968 from 1985.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 246

On to step 7:
246 can be fit into 176 0 times, resulting in a remainder of 176.
Write down 0 as next digit of the result. 
Result so far: 25880.0
The remainder is 176 after subtracting 0 from 176.
Include the next digit (0) from the dividend after 176, then repeat: 1760 / 246

Moving on to step 8:
246 goes into 1760 7 times with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 258807.0
If we subtract 1722 from 1760, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
The number 246 fits into 380 1 times, leaving a remainder of 134.
The number 1 becomes the next digit in our result. 
Result so far: 258807.1
Subtracting 246 from 380 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 10:
246 goes into 1340 5 times with a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 258807.15
Subtracting 1230 from 1340 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 11:
When dividing 1100 by 246, we get 4 with a remainder of 116.
The next digit of our result is 4. 
Result so far: 258807.154
The remainder is 116 after subtracting 984 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 12:
The number 246 fits into 1160 4 times, leaving a remainder of 176.
The next digit of our result is 4. 
Result so far: 258807.1544
Subtract 984 from 1160 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The final outcome is 258807.1544, with a leftover of 0.00176.
