Let's divide 63690987 by 318
The aim is to understand the frequency of 318 in 63690987.

Advancing to step 1:
The number 318 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 318

Moving on to step 2:
318 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
If we subtract 0 from 63, we get 63.
Take the next digit (6) from the dividend and append it to 63, then repeat: 636 / 318

Going ahead to step 3:
When dividing 636 by 318, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 636 from 636, we get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 318

Going ahead to step 4:
318 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 318

On to step 5:
When dividing 90 by 318, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 200.0
If we subtract 0 from 90, we get 90.
Take the next digit (9) from the dividend and append it to 90, then repeat: 909 / 318

On to step 6:
909 divided by 318 is 2 with a remainder of 273.
Use 2 as the next digit of our solution. 
Result so far: 2002.0
If we take 636 away from 909, we end up with 273.
Grab the next digit (8) from the dividend, add it to 273, then carry on: 2738 / 318

Going ahead to step 7:
2738 divided by 318 is 8 with a remainder of 194.
The next digit of our result is 8. 
Result so far: 20028.0
Subtract 2544 from 2738 to get 194.
Fetch the next digit (7) from the dividend, attach it to 194 and continue: 1947 / 318

Going ahead to step 8:
When dividing 1947 by 318, we get 6 with a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 200286.0
If we subtract 1908 from 1947, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
If we divide 390 by 318, we get 1 and a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 200286.1
If we take 318 away from 390, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 10:
The number 318 fits into 720 2 times, leaving a remainder of 84.
Put 2 as the next digit of the answer. 
Result so far: 200286.12
Deduct 636 from 720 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 11:
The number 318 fits into 840 2 times, leaving a remainder of 204.
Record the quotient 2 as the next digit in the result. 
Result so far: 200286.122
The remainder is 204 after subtracting 636 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

The final outcome is 200286.122, with a leftover of 0.0204.
