We look at the division of 65075130 by 402 
The aim is to understand the frequency of 402 in 65075130.

Moving on to step 1:
When dividing 6 by 402, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 402

On to step 2:
402 goes into 65 0 times with a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Fetch the next digit (0) from the dividend, attach it to 65 and continue: 650 / 402

Advancing to step 3:
650 divided by 402 is 1 with a remainder of 248.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 402 from 650 to get 248.
Bring next digit (7) of the dividend behind the 248 and repeat the process: 2487 / 402

Moving on to step 4:
When dividing 2487 by 402, we get 6 with a remainder of 75.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 2412 from 2487 to get 75.
Bring next digit (5) of the dividend behind the 75 and repeat the process: 755 / 402

Step 5:
402 can be fit into 755 1 times, resulting in a remainder of 353.
The number 1 becomes the next digit in our result. 
Result so far: 161.0
Subtract 402 from 755 to get 353.
Grab the next digit (1) from the dividend, add it to 353, then carry on: 3531 / 402

Step 6:
402 goes into 3531 8 times with a remainder of 315.
Record the quotient 8 as the next digit in the result. 
Result so far: 1618.0
The remainder is 315 after subtracting 3216 from 3531.
Grab the next digit (3) from the dividend, add it to 315, then carry on: 3153 / 402

Advancing to step 7:
402 can be fit into 3153 7 times, resulting in a remainder of 339.
The number 7 becomes the next digit in our result. 
Result so far: 16187.0
If we take 2814 away from 3153, we end up with 339.
Include the next digit (0) from the dividend after 339, then repeat: 3390 / 402

Step 8:
When dividing 3390 by 402, we get 8 with a remainder of 174.
Record the quotient 8 as the next digit in the result. 
Result so far: 161878.0
If we take 3216 away from 3390, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 9:
The number 402 fits into 1740 4 times, leaving a remainder of 132.
Put 4 as the next digit of the answer. 
Result so far: 161878.4
The remainder is 132 after subtracting 1608 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 10:
402 can be fit into 1320 3 times, resulting in a remainder of 114.
Record the quotient 3 as the next digit in the result. 
Result so far: 161878.43
If we take 1206 away from 1320, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 11:
The number 402 fits into 1140 2 times, leaving a remainder of 336.
Use 2 as the next digit of our solution. 
Result so far: 161878.432
If we subtract 804 from 1140, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 12:
The number 402 fits into 3360 8 times, leaving a remainder of 144.
The number 8 becomes the next digit in our result. 
Result so far: 161878.4328
Subtracting 3216 from 3360 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 13:
1440 divided by 402 is 3 with a remainder of 234.
Put 3 as the next digit of the answer. 
Result so far: 161878.43283
The remainder is 234 after subtracting 1206 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Step 14:
402 can be fit into 2340 5 times, resulting in a remainder of 330.
Use 5 as the next digit of our solution. 
Result so far: 161878.432835
Subtract 2010 from 2340 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 15:
3300 divided by 402 is 8 with a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 161878.4328358
The remainder is 84 after subtracting 3216 from 3300.
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 16:
If we divide 840 by 402, we get 2 and a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 161878.43283582
Subtracting 804 from 840 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 161878.43283582 and a remainder of 3.6e-08.
