68301261 ÷ 504 
The aim is to understand the frequency of 504 in 68301261.

On to step 1:
6 divided by 504 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 504

Moving on to step 2:
504 can be fit into 68 0 times, resulting in a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Include the next digit (3) from the dividend after 68, then repeat: 683 / 504

Going ahead to step 3:
The number 504 fits into 683 1 times, leaving a remainder of 179.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 504 from 683 to get 179.
Take the next digit (0) from the dividend and append it to 179, then repeat: 1790 / 504

On to step 4:
The number 504 fits into 1790 3 times, leaving a remainder of 278.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 1512 from 1790, we get 278.
Fetch the next digit (1) from the dividend, attach it to 278 and continue: 2781 / 504

Moving on to step 5:
If we divide 2781 by 504, we get 5 and a remainder of 261.
Use 5 as the next digit of our solution. 
Result so far: 135.0
The remainder is 261 after subtracting 2520 from 2781.
Bring next digit (2) of the dividend behind the 261 and repeat the process: 2612 / 504

Advancing to step 6:
The number 504 fits into 2612 5 times, leaving a remainder of 92.
Put 5 as the next digit of the answer. 
Result so far: 1355.0
Subtracting 2520 from 2612 leaves us with 92.
Include the next digit (6) from the dividend after 92, then repeat: 926 / 504

Advancing to step 7:
The number 504 fits into 926 1 times, leaving a remainder of 422.
Record the quotient 1 as the next digit in the result. 
Result so far: 13551.0
If we take 504 away from 926, we end up with 422.
Take the next digit (1) from the dividend and append it to 422, then repeat: 4221 / 504

Going ahead to step 8:
4221 divided by 504 is 8 with a remainder of 189.
Record the quotient 8 as the next digit in the result. 
Result so far: 135518.0
Subtracting 4032 from 4221 leaves us with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

On to step 9:
If we divide 1890 by 504, we get 3 and a remainder of 378.
Put 3 as the next digit of the answer. 
Result so far: 135518.3
Deduct 1512 from 1890 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

On to step 10:
When dividing 3780 by 504, we get 7 with a remainder of 252.
Use 7 as the next digit of our solution. 
Result so far: 135518.37
If we take 3528 away from 3780, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 11:
504 goes into 2520 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 135518.375
The remainder is 0 after subtracting 2520 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
When dividing 0 by 504, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 135518.375
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
The number 504 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 135518.375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 135518.375, with a leftover of 0.0.
