We're dividing 63608975 by 215 
The aim is to understand the frequency of 215 in 63608975.

Going ahead to step 1:
6 divided by 215 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
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 / 215

Moving on to step 2:
When dividing 63 by 215, we get 0 with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Take the next digit (6) from the dividend and append it to 63, then repeat: 636 / 215

Moving on to step 3:
215 can be fit into 636 2 times, resulting in a remainder of 206.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 430 from 636 and we're left with 206.
Grab the next digit (0) from the dividend, add it to 206, then carry on: 2060 / 215

On to step 4:
The number 215 fits into 2060 9 times, leaving a remainder of 125.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we subtract 1935 from 2060, we get 125.
Bring next digit (8) of the dividend behind the 125 and repeat the process: 1258 / 215

Step 5:
215 can be fit into 1258 5 times, resulting in a remainder of 183.
The number 5 becomes the next digit in our result. 
Result so far: 295.0
The remainder is 183 after subtracting 1075 from 1258.
Bring next digit (9) of the dividend behind the 183 and repeat the process: 1839 / 215

Going ahead to step 6:
The number 215 fits into 1839 8 times, leaving a remainder of 119.
The next digit of our result is 8. 
Result so far: 2958.0
Deduct 1720 from 1839 and we're left with 119.
Grab the next digit (7) from the dividend, add it to 119, then carry on: 1197 / 215

Advancing to step 7:
1197 divided by 215 is 5 with a remainder of 122.
Write down 5 as next digit of the result. 
Result so far: 29585.0
If we take 1075 away from 1197, we end up with 122.
Take the next digit (5) from the dividend and append it to 122, then repeat: 1225 / 215

On to step 8:
215 goes into 1225 5 times with a remainder of 150.
The next digit of our result is 5. 
Result so far: 295855.0
If we take 1075 away from 1225, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 9:
If we divide 1500 by 215, we get 6 and a remainder of 210.
Write down 6 as next digit of the result. 
Result so far: 295855.6
Subtracting 1290 from 1500 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 10:
2100 divided by 215 is 9 with a remainder of 165.
Use 9 as the next digit of our solution. 
Result so far: 295855.69
Deduct 1935 from 2100 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 11:
215 goes into 1650 7 times with a remainder of 145.
Put 7 as the next digit of the answer. 
Result so far: 295855.697
If we take 1505 away from 1650, we end up 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.

Advancing to step 12:
215 goes into 1450 6 times with a remainder of 160.
The number 6 becomes the next digit in our result. 
Result so far: 295855.6976
The remainder is 160 after subtracting 1290 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 13:
215 goes into 1600 7 times with a remainder of 95.
Record the quotient 7 as the next digit in the result. 
Result so far: 295855.69767
Subtracting 1505 from 1600 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 14:
If we divide 950 by 215, we get 4 and a remainder of 90.
Record the quotient 4 as the next digit in the result. 
Result so far: 295855.697674
Subtracting 860 from 950 leaves us 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.

On to step 15:
The number 215 fits into 900 4 times, leaving a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 295855.6976744
If we subtract 860 from 900, we 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.

In conclusion, the division gives 295855.6976744 with a balance of 4e-07.
