Let's divide 17503785 by 725
The aim is to understand the frequency of 725 in 17503785.

Going ahead to step 1:
When dividing 1 by 725, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 725

Moving on to step 2:
If we divide 17 by 725, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Bring next digit (5) of the dividend behind the 17 and repeat the process: 175 / 725

Moving on to step 3:
If we divide 175 by 725, we get 0 and a remainder of 175.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 175 after subtracting 0 from 175.
Grab the next digit (0) from the dividend, add it to 175, then carry on: 1750 / 725

Advancing to step 4:
If we divide 1750 by 725, we get 2 and a remainder of 300.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1450 from 1750 and we're left with 300.
Fetch the next digit (3) from the dividend, attach it to 300 and continue: 3003 / 725

Let's proceed to step 5:
725 can be fit into 3003 4 times, resulting in a remainder of 103.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we take 2900 away from 3003, we end up with 103.
Take the next digit (7) from the dividend and append it to 103, then repeat: 1037 / 725

Step 6:
If we divide 1037 by 725, we get 1 and a remainder of 312.
The number 1 becomes the next digit in our result. 
Result so far: 241.0
If we take 725 away from 1037, we end up with 312.
Bring next digit (8) of the dividend behind the 312 and repeat the process: 3128 / 725

Step 7:
The number 725 fits into 3128 4 times, leaving a remainder of 228.
Write down 4 as next digit of the result. 
Result so far: 2414.0
The remainder is 228 after subtracting 2900 from 3128.
Take the next digit (5) from the dividend and append it to 228, then repeat: 2285 / 725

Going ahead to step 8:
The number 725 fits into 2285 3 times, leaving a remainder of 110.
Put 3 as the next digit of the answer. 
Result so far: 24143.0
If we subtract 2175 from 2285, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 9:
725 can be fit into 1100 1 times, resulting in a remainder of 375.
Write down 1 as next digit of the result. 
Result so far: 24143.1
Subtracting 725 from 1100 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 10:
The number 725 fits into 3750 5 times, leaving a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 24143.15
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.

Going ahead 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: 24143.151
If we subtract 725 from 1250, we get 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Going ahead to step 12:
If we divide 5250 by 725, we get 7 and a remainder of 175.
Put 7 as the next digit of the answer. 
Result so far: 24143.1517
Subtract 5075 from 5250 to 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.

Let's proceed to step 13:
If we divide 1750 by 725, we get 2 and a remainder of 300.
The number 2 becomes the next digit in our result. 
Result so far: 24143.15172
The remainder is 300 after subtracting 1450 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 14:
3000 divided by 725 is 4 with a remainder of 100.
Use 4 as the next digit of our solution. 
Result so far: 24143.151724
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 15:
725 goes into 1000 1 times with a remainder of 275.
Record the quotient 1 as the next digit in the result. 
Result so far: 24143.1517241
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.

On to step 16:
If we divide 2750 by 725, we get 3 and a remainder of 575.
The number 3 becomes the next digit in our result. 
Result so far: 24143.15172413
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.

The final outcome is 24143.15172413, with a leftover of 5.75e-07.
