64618418 ÷ 202 
The aim is to understand the frequency of 202 in 64618418.

Moving on to step 1:
When dividing 6 by 202, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 202

Let's proceed to step 2:
202 can be fit into 64 0 times, resulting in a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Fetch the next digit (6) from the dividend, attach it to 64 and continue: 646 / 202

Going ahead to step 3:
202 goes into 646 3 times with a remainder of 40.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 606 from 646 to get 40.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 202

On to step 4:
401 divided by 202 is 1 with a remainder of 199.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 202 from 401 to get 199.
Fetch the next digit (8) from the dividend, attach it to 199 and continue: 1998 / 202

Let's proceed to step 5:
202 can be fit into 1998 9 times, resulting in a remainder of 180.
Put 9 as the next digit of the answer. 
Result so far: 319.0
Subtract 1818 from 1998 to get 180.
Grab the next digit (4) from the dividend, add it to 180, then carry on: 1804 / 202

Let's proceed to step 6:
202 goes into 1804 8 times with a remainder of 188.
Write down 8 as next digit of the result. 
Result so far: 3198.0
Subtracting 1616 from 1804 leaves us with 188.
Take the next digit (1) from the dividend and append it to 188, then repeat: 1881 / 202

Moving on to step 7:
If we divide 1881 by 202, we get 9 and a remainder of 63.
Write down 9 as next digit of the result. 
Result so far: 31989.0
The remainder is 63 after subtracting 1818 from 1881.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 202

Moving on to step 8:
638 divided by 202 is 3 with a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 319893.0
If we subtract 606 from 638, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
320 divided by 202 is 1 with a remainder of 118.
Put 1 as the next digit of the answer. 
Result so far: 319893.1
The remainder is 118 after subtracting 202 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 10:
When dividing 1180 by 202, we get 5 with a remainder of 170.
Record the quotient 5 as the next digit in the result. 
Result so far: 319893.15
Subtracting 1010 from 1180 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 11:
If we divide 1700 by 202, we get 8 and a remainder of 84.
Record the quotient 8 as the next digit in the result. 
Result so far: 319893.158
Deduct 1616 from 1700 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.

Moving on to step 12:
202 goes into 840 4 times with a remainder of 32.
The next digit of our result is 4. 
Result so far: 319893.1584
Subtract 808 from 840 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
202 can be fit into 320 1 times, resulting in a remainder of 118.
The number 1 becomes the next digit in our result. 
Result so far: 319893.15841
Subtract 202 from 320 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 14:
The number 202 fits into 1180 5 times, leaving a remainder of 170.
Put 5 as the next digit of the answer. 
Result so far: 319893.158415
Deduct 1010 from 1180 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 15:
When dividing 1700 by 202, we get 8 with a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 319893.1584158
If we subtract 1616 from 1700, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 16:
202 can be fit into 840 4 times, resulting in a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 319893.15841584
If we take 808 away from 840, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 319893.15841584 with a remainder of 3.2e-08.
