Let's divide 64125697 by 804
The aim is to understand the frequency of 804 in 64125697.

On to step 1:
The number 804 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 804

On to step 2:
804 can be fit into 64 0 times, resulting in a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Bring next digit (1) of the dividend behind the 64 and repeat the process: 641 / 804

On to step 3:
When dividing 641 by 804, we get 0 with a remainder of 641.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 641 and we're left with 641.
Include the next digit (2) from the dividend after 641, then repeat: 6412 / 804

Let's proceed to step 4:
If we divide 6412 by 804, we get 7 and a remainder of 784.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 5628 from 6412 and we're left with 784.
Take the next digit (5) from the dividend and append it to 784, then repeat: 7845 / 804

Moving on to step 5:
804 can be fit into 7845 9 times, resulting in a remainder of 609.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
Subtracting 7236 from 7845 leaves us with 609.
Bring next digit (6) of the dividend behind the 609 and repeat the process: 6096 / 804

Step 6:
The number 804 fits into 6096 7 times, leaving a remainder of 468.
Record the quotient 7 as the next digit in the result. 
Result so far: 797.0
The remainder is 468 after subtracting 5628 from 6096.
Fetch the next digit (9) from the dividend, attach it to 468 and continue: 4689 / 804

Going ahead to step 7:
The number 804 fits into 4689 5 times, leaving a remainder of 669.
Write down 5 as next digit of the result. 
Result so far: 7975.0
The remainder is 669 after subtracting 4020 from 4689.
Bring next digit (7) of the dividend behind the 669 and repeat the process: 6697 / 804

Step 8:
If we divide 6697 by 804, we get 8 and a remainder of 265.
Write down 8 as next digit of the result. 
Result so far: 79758.0
Deduct 6432 from 6697 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Advancing to step 9:
804 can be fit into 2650 3 times, resulting in a remainder of 238.
The next digit of our result is 3. 
Result so far: 79758.3
The remainder is 238 after subtracting 2412 from 2650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 10:
804 goes into 2380 2 times with a remainder of 772.
Put 2 as the next digit of the answer. 
Result so far: 79758.32
Subtract 1608 from 2380 to get 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Moving on to step 11:
804 can be fit into 7720 9 times, resulting in a remainder of 484.
Use 9 as the next digit of our solution. 
Result so far: 79758.329
Subtracting 7236 from 7720 leaves us with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Moving on to step 12:
804 goes into 4840 6 times with a remainder of 16.
The next digit of our result is 6. 
Result so far: 79758.3296
If we subtract 4824 from 4840, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
The number 804 fits into 160 0 times, leaving a remainder of 160.
The next digit of our result is 0. 
Result so far: 79758.3296
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 14:
If we divide 1600 by 804, we get 1 and a remainder of 796.
Put 1 as the next digit of the answer. 
Result so far: 79758.329601
Subtracting 804 from 1600 leaves us with 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Step 15:
When dividing 7960 by 804, we get 9 with a remainder of 724.
Put 9 as the next digit of the answer. 
Result so far: 79758.3296019
Subtracting 7236 from 7960 leaves us with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Let's proceed to step 16:
7240 divided by 804 is 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 79758.32960199
Deduct 7236 from 7240 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 79758.32960199 with a remainder of 4e-09.
