64902161 divided by 357 
The aim is to understand the frequency of 357 in 64902161.

Step 1:
357 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 357

Advancing to step 2:
357 can be fit into 64 0 times, resulting in a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Bring next digit (9) of the dividend behind the 64 and repeat the process: 649 / 357

Moving on to step 3:
The number 357 fits into 649 1 times, leaving a remainder of 292.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 357 from 649 leaves us with 292.
Include the next digit (0) from the dividend after 292, then repeat: 2920 / 357

Let's proceed to step 4:
If we divide 2920 by 357, we get 8 and a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we take 2856 away from 2920, we end up with 64.
Bring next digit (2) of the dividend behind the 64 and repeat the process: 642 / 357

On to step 5:
If we divide 642 by 357, we get 1 and a remainder of 285.
The number 1 becomes the next digit in our result. 
Result so far: 181.0
If we take 357 away from 642, we end up with 285.
Include the next digit (1) from the dividend after 285, then repeat: 2851 / 357

Let's proceed to step 6:
357 can be fit into 2851 7 times, resulting in a remainder of 352.
Put 7 as the next digit of the answer. 
Result so far: 1817.0
Deduct 2499 from 2851 and we're left with 352.
Take the next digit (6) from the dividend and append it to 352, then repeat: 3526 / 357

Step 7:
If we divide 3526 by 357, we get 9 and a remainder of 313.
Record the quotient 9 as the next digit in the result. 
Result so far: 18179.0
If we take 3213 away from 3526, we end up with 313.
Fetch the next digit (1) from the dividend, attach it to 313 and continue: 3131 / 357

Going ahead to step 8:
If we divide 3131 by 357, we get 8 and a remainder of 275.
Write down 8 as next digit of the result. 
Result so far: 181798.0
The remainder is 275 after subtracting 2856 from 3131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 9:
The number 357 fits into 2750 7 times, leaving a remainder of 251.
Write down 7 as next digit of the result. 
Result so far: 181798.7
If we take 2499 away from 2750, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Advancing to step 10:
The number 357 fits into 2510 7 times, leaving a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 181798.77
If we take 2499 away from 2510, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

In conclusion, the division gives 181798.77 with a balance of 0.011.
