We're dividing 63650691 by 202 
The aim is to understand the frequency of 202 in 63650691.

Step 1:
If we divide 6 by 202, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 202

Advancing to step 2:
63 divided by 202 is 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Bring next digit (6) of the dividend behind the 63 and repeat the process: 636 / 202

Let's proceed to step 3:
The number 202 fits into 636 3 times, leaving a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 606 from 636 leaves us with 30.
Take the next digit (5) from the dividend and append it to 30, then repeat: 305 / 202

On to step 4:
305 divided by 202 is 1 with a remainder of 103.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we subtract 202 from 305, we get 103.
Append the next digit (0) from the dividend to 103 and continue with: 1030 / 202

Let's proceed to step 5:
202 goes into 1030 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 315.0
Deduct 1010 from 1030 and we're left with 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 202

Step 6:
202 goes into 206 1 times with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 3151.0
Deduct 202 from 206 and we're left with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 202

Going ahead to step 7:
49 divided by 202 is 0 with a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 31510.0
If we subtract 0 from 49, we get 49.
Include the next digit (1) from the dividend after 49, then repeat: 491 / 202

Step 8:
When dividing 491 by 202, we get 2 with a remainder of 87.
Put 2 as the next digit of the answer. 
Result so far: 315102.0
Deduct 404 from 491 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 9:
202 can be fit into 870 4 times, resulting in a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 315102.4
If we take 808 away from 870, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 10:
When dividing 620 by 202, we get 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 315102.43
If we take 606 away from 620, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
The number 202 fits into 140 0 times, leaving a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 315102.43
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 12:
202 goes into 1400 6 times with a remainder of 188.
Write down 6 as next digit of the result. 
Result so far: 315102.4306
If we take 1212 away from 1400, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 13:
If we divide 1880 by 202, we get 9 and a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 315102.43069
If we take 1818 away from 1880, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 14:
If we divide 620 by 202, we get 3 and a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 315102.430693
The remainder is 14 after subtracting 606 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 15:
When dividing 140 by 202, we get 0 with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 315102.430693
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 16:
202 goes into 1400 6 times with a remainder of 188.
The number 6 becomes the next digit in our result. 
Result so far: 315102.43069306
The remainder is 188 after subtracting 1212 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

After the division, we end up with 315102.43069306 and a remainder of 1.88e-07.
