We divide 64917579 by 804
The aim is to understand the frequency of 804 in 64917579.

Going ahead to step 1:
The number 804 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 804

Step 2:
804 goes into 64 0 times with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Grab the next digit (9) from the dividend, add it to 64, then carry on: 649 / 804

Moving on to step 3:
The number 804 fits into 649 0 times, leaving a remainder of 649.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 649 leaves us with 649.
Fetch the next digit (1) from the dividend, attach it to 649 and continue: 6491 / 804

On to step 4:
804 goes into 6491 8 times with a remainder of 59.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 6432 from 6491 and we're left with 59.
Take the next digit (7) from the dividend and append it to 59, then repeat: 597 / 804

Advancing to step 5:
If we divide 597 by 804, we get 0 and a remainder of 597.
The next digit of our result is 0. 
Result so far: 80.0
If we subtract 0 from 597, we get 597.
Bring next digit (5) of the dividend behind the 597 and repeat the process: 5975 / 804

On to step 6:
The number 804 fits into 5975 7 times, leaving a remainder of 347.
Write down 7 as next digit of the result. 
Result so far: 807.0
If we subtract 5628 from 5975, we get 347.
Append the next digit (7) from the dividend to 347 and continue with: 3477 / 804

Going ahead to step 7:
When dividing 3477 by 804, we get 4 with a remainder of 261.
Record the quotient 4 as the next digit in the result. 
Result so far: 8074.0
Deduct 3216 from 3477 and we're left with 261.
Fetch the next digit (9) from the dividend, attach it to 261 and continue: 2619 / 804

Going ahead to step 8:
When dividing 2619 by 804, we get 3 with a remainder of 207.
Put 3 as the next digit of the answer. 
Result so far: 80743.0
Subtracting 2412 from 2619 leaves us with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Advancing to step 9:
2070 divided by 804 is 2 with a remainder of 462.
The next digit of our result is 2. 
Result so far: 80743.2
If we subtract 1608 from 2070, we get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

On to step 10:
If we divide 4620 by 804, we get 5 and a remainder of 600.
Put 5 as the next digit of the answer. 
Result so far: 80743.25
The remainder is 600 after subtracting 4020 from 4620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 11:
6000 divided by 804 is 7 with a remainder of 372.
Use 7 as the next digit of our solution. 
Result so far: 80743.257
The remainder is 372 after subtracting 5628 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Let's proceed to step 12:
The number 804 fits into 3720 4 times, leaving a remainder of 504.
Record the quotient 4 as the next digit in the result. 
Result so far: 80743.2574
Subtract 3216 from 3720 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

On to step 13:
5040 divided by 804 is 6 with a remainder of 216.
Use 6 as the next digit of our solution. 
Result so far: 80743.25746
Subtract 4824 from 5040 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 14:
2160 divided by 804 is 2 with a remainder of 552.
The next digit of our result is 2. 
Result so far: 80743.257462
Deduct 1608 from 2160 and we're left with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Moving on to step 15:
When dividing 5520 by 804, we get 6 with a remainder of 696.
Use 6 as the next digit of our solution. 
Result so far: 80743.2574626
The remainder is 696 after subtracting 4824 from 5520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

On to step 16:
804 can be fit into 6960 8 times, resulting in a remainder of 528.
The number 8 becomes the next digit in our result. 
Result so far: 80743.25746268
The remainder is 528 after subtracting 6432 from 6960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

After the division, we end up with 80743.25746268 and a remainder of 5.28e-07.
