We look at the division of 64226062 by 725 
The aim is to understand the frequency of 725 in 64226062.

Going ahead to step 1:
725 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 725

Advancing to step 2:
If we divide 64 by 725, we get 0 and a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Bring next digit (2) of the dividend behind the 64 and repeat the process: 642 / 725

Going ahead to step 3:
When dividing 642 by 725, we get 0 with a remainder of 642.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 642 leaves us with 642.
Include the next digit (2) from the dividend after 642, then repeat: 6422 / 725

Going ahead to step 4:
6422 divided by 725 is 8 with a remainder of 622.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 622 after subtracting 5800 from 6422.
Bring next digit (6) of the dividend behind the 622 and repeat the process: 6226 / 725

On to step 5:
The number 725 fits into 6226 8 times, leaving a remainder of 426.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
If we take 5800 away from 6226, we end up with 426.
Include the next digit (0) from the dividend after 426, then repeat: 4260 / 725

Advancing to step 6:
4260 divided by 725 is 5 with a remainder of 635.
The number 5 becomes the next digit in our result. 
Result so far: 885.0
If we take 3625 away from 4260, we end up with 635.
Bring next digit (6) of the dividend behind the 635 and repeat the process: 6356 / 725

Moving on to step 7:
725 goes into 6356 8 times with a remainder of 556.
Record the quotient 8 as the next digit in the result. 
Result so far: 8858.0
Subtract 5800 from 6356 to get 556.
Include the next digit (2) from the dividend after 556, then repeat: 5562 / 725

On to step 8:
If we divide 5562 by 725, we get 7 and a remainder of 487.
The number 7 becomes the next digit in our result. 
Result so far: 88587.0
If we subtract 5075 from 5562, we get 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Advancing to step 9:
The number 725 fits into 4870 6 times, leaving a remainder of 520.
Write down 6 as next digit of the result. 
Result so far: 88587.6
If we subtract 4350 from 4870, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 10:
When dividing 5200 by 725, we get 7 with a remainder of 125.
Record the quotient 7 as the next digit in the result. 
Result so far: 88587.67
Deduct 5075 from 5200 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 11:
If we divide 1250 by 725, we get 1 and a remainder of 525.
Write down 1 as next digit of the result. 
Result so far: 88587.671
The remainder is 525 after subtracting 725 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Advancing to step 12:
If we divide 5250 by 725, we get 7 and a remainder of 175.
The number 7 becomes the next digit in our result. 
Result so far: 88587.6717
If we subtract 5075 from 5250, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 13:
The number 725 fits into 1750 2 times, leaving a remainder of 300.
Put 2 as the next digit of the answer. 
Result so far: 88587.67172
Subtracting 1450 from 1750 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 14:
The number 725 fits into 3000 4 times, leaving a remainder of 100.
Record the quotient 4 as the next digit in the result. 
Result so far: 88587.671724
If we take 2900 away from 3000, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 15:
The number 725 fits into 1000 1 times, leaving a remainder of 275.
Put 1 as the next digit of the answer. 
Result so far: 88587.6717241
Subtracting 725 from 1000 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 16:
725 can be fit into 2750 3 times, resulting in a remainder of 575.
Write down 3 as next digit of the result. 
Result so far: 88587.67172413
Subtract 2175 from 2750 to get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

After the division, we end up with 88587.67172413 and a remainder of 5.75e-07.
