We're dividing 36437209 by 577 
The aim is to understand the frequency of 577 in 36437209.

Advancing to step 1:
577 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 577

Let's proceed to step 2:
36 divided by 577 is 0 with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Grab the next digit (4) from the dividend, add it to 36, then carry on: 364 / 577

On to step 3:
If we divide 364 by 577, we get 0 and a remainder of 364.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 364 leaves us with 364.
Bring next digit (3) of the dividend behind the 364 and repeat the process: 3643 / 577

Advancing to step 4:
If we divide 3643 by 577, we get 6 and a remainder of 181.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 3462 from 3643 to get 181.
Include the next digit (7) from the dividend after 181, then repeat: 1817 / 577

On to step 5:
577 can be fit into 1817 3 times, resulting in a remainder of 86.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
If we take 1731 away from 1817, we end up with 86.
Bring next digit (2) of the dividend behind the 86 and repeat the process: 862 / 577

Let's proceed to step 6:
When dividing 862 by 577, we get 1 with a remainder of 285.
Use 1 as the next digit of our solution. 
Result so far: 631.0
If we take 577 away from 862, we end up with 285.
Fetch the next digit (0) from the dividend, attach it to 285 and continue: 2850 / 577

Step 7:
When dividing 2850 by 577, we get 4 with a remainder of 542.
The number 4 becomes the next digit in our result. 
Result so far: 6314.0
Deduct 2308 from 2850 and we're left with 542.
Include the next digit (9) from the dividend after 542, then repeat: 5429 / 577

On to step 8:
577 goes into 5429 9 times with a remainder of 236.
The next digit of our result is 9. 
Result so far: 63149.0
Deduct 5193 from 5429 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 9:
2360 divided by 577 is 4 with a remainder of 52.
The next digit of our result is 4. 
Result so far: 63149.4
The remainder is 52 after subtracting 2308 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 10:
If we divide 520 by 577, we get 0 and a remainder of 520.
The number 0 becomes the next digit in our result. 
Result so far: 63149.4
Deduct 0 from 520 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 11:
The number 577 fits into 5200 9 times, leaving a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 63149.409
Subtracting 5193 from 5200 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
577 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 63149.409
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 13:
When dividing 700 by 577, we get 1 with a remainder of 123.
Write down 1 as next digit of the result. 
Result so far: 63149.40901
Deduct 577 from 700 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 14:
If we divide 1230 by 577, we get 2 and a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 63149.409012
Subtract 1154 from 1230 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 15:
If we divide 760 by 577, we get 1 and a remainder of 183.
Put 1 as the next digit of the answer. 
Result so far: 63149.4090121
If we subtract 577 from 760, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Moving on to step 16:
If we divide 1830 by 577, we get 3 and a remainder of 99.
Put 3 as the next digit of the answer. 
Result so far: 63149.40901213
Deduct 1731 from 1830 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

In conclusion, the division gives 63149.40901213 with a balance of 9.9e-08.
