We're dividing 25181628 by 607 
The aim is to understand the frequency of 607 in 25181628.

Going ahead to step 1:
When dividing 2 by 607, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 607

Moving on to step 2:
When dividing 25 by 607, we get 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 607

On to step 3:
251 divided by 607 is 0 with a remainder of 251.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 251 leaves us with 251.
Fetch the next digit (8) from the dividend, attach it to 251 and continue: 2518 / 607

Let's proceed to step 4:
When dividing 2518 by 607, we get 4 with a remainder of 90.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 2428 from 2518 leaves us with 90.
Include the next digit (1) from the dividend after 90, then repeat: 901 / 607

Moving on to step 5:
When dividing 901 by 607, we get 1 with a remainder of 294.
Write down 1 as next digit of the result. 
Result so far: 41.0
The remainder is 294 after subtracting 607 from 901.
Grab the next digit (6) from the dividend, add it to 294, then carry on: 2946 / 607

Going ahead to step 6:
2946 divided by 607 is 4 with a remainder of 518.
Use 4 as the next digit of our solution. 
Result so far: 414.0
If we take 2428 away from 2946, we end up with 518.
Append the next digit (2) from the dividend to 518 and continue with: 5182 / 607

Step 7:
607 goes into 5182 8 times with a remainder of 326.
Record the quotient 8 as the next digit in the result. 
Result so far: 4148.0
The remainder is 326 after subtracting 4856 from 5182.
Take the next digit (8) from the dividend and append it to 326, then repeat: 3268 / 607

Step 8:
607 goes into 3268 5 times with a remainder of 233.
Record the quotient 5 as the next digit in the result. 
Result so far: 41485.0
Subtracting 3035 from 3268 leaves us with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Going ahead to step 9:
607 goes into 2330 3 times with a remainder of 509.
The next digit of our result is 3. 
Result so far: 41485.3
If we take 1821 away from 2330, we end up with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Step 10:
If we divide 5090 by 607, we get 8 and a remainder of 234.
Record the quotient 8 as the next digit in the result. 
Result so far: 41485.38
If we take 4856 away from 5090, we end up with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Let's proceed to step 11:
607 goes into 2340 3 times with a remainder of 519.
Use 3 as the next digit of our solution. 
Result so far: 41485.383
Subtract 1821 from 2340 to get 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Going ahead to step 12:
When dividing 5190 by 607, we get 8 with a remainder of 334.
Record the quotient 8 as the next digit in the result. 
Result so far: 41485.3838
The remainder is 334 after subtracting 4856 from 5190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Let's proceed to step 13:
If we divide 3340 by 607, we get 5 and a remainder of 305.
Write down 5 as next digit of the result. 
Result so far: 41485.38385
If we subtract 3035 from 3340, we get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 14:
607 goes into 3050 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 41485.383855
Deduct 3035 from 3050 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 41485.383855 and a remainder of 1.5e-06.
