63101501 ÷ 725 
The aim is to understand the frequency of 725 in 63101501.

On to step 1:
If we divide 6 by 725, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 725

Advancing to step 2:
725 can be fit into 63 0 times, resulting in a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Append the next digit (1) from the dividend to 63 and continue with: 631 / 725

On to step 3:
The number 725 fits into 631 0 times, leaving a remainder of 631.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 631 after subtracting 0 from 631.
Include the next digit (0) from the dividend after 631, then repeat: 6310 / 725

Let's proceed to step 4:
The number 725 fits into 6310 8 times, leaving a remainder of 510.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 5800 from 6310, we get 510.
Bring next digit (1) of the dividend behind the 510 and repeat the process: 5101 / 725

Step 5:
725 goes into 5101 7 times with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 87.0
If we subtract 5075 from 5101, we get 26.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 725

Let's proceed to step 6:
725 goes into 265 0 times with a remainder of 265.
Record the quotient 0 as the next digit in the result. 
Result so far: 870.0
Deduct 0 from 265 and we're left with 265.
Bring next digit (0) of the dividend behind the 265 and repeat the process: 2650 / 725

Moving on to step 7:
725 goes into 2650 3 times with a remainder of 475.
The next digit of our result is 3. 
Result so far: 8703.0
The remainder is 475 after subtracting 2175 from 2650.
Append the next digit (1) from the dividend to 475 and continue with: 4751 / 725

Advancing to step 8:
725 can be fit into 4751 6 times, resulting in a remainder of 401.
Use 6 as the next digit of our solution. 
Result so far: 87036.0
The remainder is 401 after subtracting 4350 from 4751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Going ahead to step 9:
If we divide 4010 by 725, we get 5 and a remainder of 385.
Use 5 as the next digit of our solution. 
Result so far: 87036.5
If we subtract 3625 from 4010, we get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Let's proceed to step 10:
725 goes into 3850 5 times with a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 87036.55
If we take 3625 away from 3850, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

The quotient of the division is 87036.55, and the remainder is 0.225.
