We look at the division of 89737699 by 804 
The aim is to understand the frequency of 804 in 89737699.

Going ahead to step 1:
804 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 804

Step 2:
When dividing 89 by 804, we get 0 with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Fetch the next digit (7) from the dividend, attach it to 89 and continue: 897 / 804

On to step 3:
If we divide 897 by 804, we get 1 and a remainder of 93.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 93 after subtracting 804 from 897.
Fetch the next digit (3) from the dividend, attach it to 93 and continue: 933 / 804

Step 4:
When dividing 933 by 804, we get 1 with a remainder of 129.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 804 from 933, we get 129.
Take the next digit (7) from the dividend and append it to 129, then repeat: 1297 / 804

On to step 5:
If we divide 1297 by 804, we get 1 and a remainder of 493.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
Deduct 804 from 1297 and we're left with 493.
Bring next digit (6) of the dividend behind the 493 and repeat the process: 4936 / 804

Advancing to step 6:
804 can be fit into 4936 6 times, resulting in a remainder of 112.
The next digit of our result is 6. 
Result so far: 1116.0
Deduct 4824 from 4936 and we're left with 112.
Bring next digit (9) of the dividend behind the 112 and repeat the process: 1129 / 804

Step 7:
The number 804 fits into 1129 1 times, leaving a remainder of 325.
Use 1 as the next digit of our solution. 
Result so far: 11161.0
If we subtract 804 from 1129, we get 325.
Fetch the next digit (9) from the dividend, attach it to 325 and continue: 3259 / 804

Step 8:
If we divide 3259 by 804, we get 4 and a remainder of 43.
Record the quotient 4 as the next digit in the result. 
Result so far: 111614.0
The remainder is 43 after subtracting 3216 from 3259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 9:
When dividing 430 by 804, we get 0 with a remainder of 430.
The number 0 becomes the next digit in our result. 
Result so far: 111614.0
If we take 0 away from 430, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

On to step 10:
4300 divided by 804 is 5 with a remainder of 280.
Use 5 as the next digit of our solution. 
Result so far: 111614.05
The remainder is 280 after subtracting 4020 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 11:
804 goes into 2800 3 times with a remainder of 388.
Record the quotient 3 as the next digit in the result. 
Result so far: 111614.053
If we take 2412 away from 2800, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Step 12:
The number 804 fits into 3880 4 times, leaving a remainder of 664.
Record the quotient 4 as the next digit in the result. 
Result so far: 111614.0534
If we subtract 3216 from 3880, we get 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Advancing to step 13:
The number 804 fits into 6640 8 times, leaving a remainder of 208.
The number 8 becomes the next digit in our result. 
Result so far: 111614.05348
If we subtract 6432 from 6640, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 14:
2080 divided by 804 is 2 with a remainder of 472.
Use 2 as the next digit of our solution. 
Result so far: 111614.053482
If we take 1608 away from 2080, we end up with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 15:
When dividing 4720 by 804, we get 5 with a remainder of 700.
The number 5 becomes the next digit in our result. 
Result so far: 111614.0534825
Deduct 4020 from 4720 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 16:
804 can be fit into 7000 8 times, resulting in a remainder of 568.
The number 8 becomes the next digit in our result. 
Result so far: 111614.05348258
If we subtract 6432 from 7000, we get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

The final result is 111614.05348258 with a remainder of 5.68e-07.
