We look at the division of 70479698 by 504 
The aim is to understand the frequency of 504 in 70479698.

Advancing to step 1:
7 divided by 504 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 504

On to step 2:
The number 504 fits into 70 0 times, leaving a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Fetch the next digit (4) from the dividend, attach it to 70 and continue: 704 / 504

Going ahead to step 3:
504 goes into 704 1 times with a remainder of 200.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 504 from 704 to get 200.
Bring next digit (7) of the dividend behind the 200 and repeat the process: 2007 / 504

On to step 4:
504 can be fit into 2007 3 times, resulting in a remainder of 495.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 1512 away from 2007, we end up with 495.
Append the next digit (9) from the dividend to 495 and continue with: 4959 / 504

Moving on to step 5:
The number 504 fits into 4959 9 times, leaving a remainder of 423.
Put 9 as the next digit of the answer. 
Result so far: 139.0
Subtracting 4536 from 4959 leaves us with 423.
Bring next digit (6) of the dividend behind the 423 and repeat the process: 4236 / 504

On to step 6:
4236 divided by 504 is 8 with a remainder of 204.
Record the quotient 8 as the next digit in the result. 
Result so far: 1398.0
If we subtract 4032 from 4236, we get 204.
Bring next digit (9) of the dividend behind the 204 and repeat the process: 2049 / 504

Going ahead to step 7:
504 goes into 2049 4 times with a remainder of 33.
Record the quotient 4 as the next digit in the result. 
Result so far: 13984.0
If we subtract 2016 from 2049, we get 33.
Fetch the next digit (8) from the dividend, attach it to 33 and continue: 338 / 504

Step 8:
504 goes into 338 0 times with a remainder of 338.
The next digit of our result is 0. 
Result so far: 139840.0
Deduct 0 from 338 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 9:
If we divide 3380 by 504, we get 6 and a remainder of 356.
The number 6 becomes the next digit in our result. 
Result so far: 139840.6
If we subtract 3024 from 3380, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 10:
If we divide 3560 by 504, we get 7 and a remainder of 32.
The next digit of our result is 7. 
Result so far: 139840.67
Deduct 3528 from 3560 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
504 can be fit into 320 0 times, resulting in a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 139840.67
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 12:
When dividing 3200 by 504, we get 6 with a remainder of 176.
Put 6 as the next digit of the answer. 
Result so far: 139840.6706
If we subtract 3024 from 3200, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 13:
When dividing 1760 by 504, we get 3 with a remainder of 248.
The number 3 becomes the next digit in our result. 
Result so far: 139840.67063
The remainder is 248 after subtracting 1512 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 14:
When dividing 2480 by 504, we get 4 with a remainder of 464.
Use 4 as the next digit of our solution. 
Result so far: 139840.670634
If we take 2016 away from 2480, we end up with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 15:
If we divide 4640 by 504, we get 9 and a remainder of 104.
Write down 9 as next digit of the result. 
Result so far: 139840.6706349
The remainder is 104 after subtracting 4536 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 16:
If we divide 1040 by 504, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 139840.67063492
If we subtract 1008 from 1040, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 139840.67063492 with a balance of 3.2e-08.
