We're dividing 50551361 by 725 
The aim is to understand the frequency of 725 in 50551361.

Advancing to step 1:
The number 725 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 725

On to step 2:
If we divide 50 by 725, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Bring next digit (5) of the dividend behind the 50 and repeat the process: 505 / 725

Going ahead to step 3:
725 can be fit into 505 0 times, resulting in a remainder of 505.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 505 and we're left with 505.
Fetch the next digit (5) from the dividend, attach it to 505 and continue: 5055 / 725

Advancing to step 4:
5055 divided by 725 is 6 with a remainder of 705.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 4350 from 5055 leaves us with 705.
Append the next digit (1) from the dividend to 705 and continue with: 7051 / 725

Let's proceed to step 5:
725 can be fit into 7051 9 times, resulting in a remainder of 526.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
If we take 6525 away from 7051, we end up with 526.
Include the next digit (3) from the dividend after 526, then repeat: 5263 / 725

Let's proceed to step 6:
725 goes into 5263 7 times with a remainder of 188.
Record the quotient 7 as the next digit in the result. 
Result so far: 697.0
If we take 5075 away from 5263, we end up with 188.
Bring next digit (6) of the dividend behind the 188 and repeat the process: 1886 / 725

Step 7:
When dividing 1886 by 725, we get 2 with a remainder of 436.
The number 2 becomes the next digit in our result. 
Result so far: 6972.0
Subtract 1450 from 1886 to get 436.
Take the next digit (1) from the dividend and append it to 436, then repeat: 4361 / 725

Let's proceed to step 8:
725 goes into 4361 6 times with a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 69726.0
Deduct 4350 from 4361 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
The number 725 fits into 110 0 times, leaving a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 69726.0
If we take 0 away from 110, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 10:
If we divide 1100 by 725, we get 1 and a remainder of 375.
Write down 1 as next digit of the result. 
Result so far: 69726.01
If we subtract 725 from 1100, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 11:
3750 divided by 725 is 5 with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 69726.015
The remainder is 125 after subtracting 3625 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 12:
1250 divided by 725 is 1 with a remainder of 525.
Write down 1 as next digit of the result. 
Result so far: 69726.0151
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.

Moving on to step 13:
725 goes into 5250 7 times with a remainder of 175.
The number 7 becomes the next digit in our result. 
Result so far: 69726.01517
If we take 5075 away from 5250, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 14:
725 can be fit into 1750 2 times, resulting in a remainder of 300.
Use 2 as the next digit of our solution. 
Result so far: 69726.015172
Deduct 1450 from 1750 and we're left 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.

Step 15:
When dividing 3000 by 725, we get 4 with a remainder of 100.
Put 4 as the next digit of the answer. 
Result so far: 69726.0151724
Subtract 2900 from 3000 to get 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 16:
If we divide 1000 by 725, we get 1 and a remainder of 275.
The number 1 becomes the next digit in our result. 
Result so far: 69726.01517241
The remainder is 275 after subtracting 725 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

After the division, we end up with 69726.01517241 and a remainder of 2.75e-07.
