25519170 divided by 671 
The aim is to understand the frequency of 671 in 25519170.

Step 1:
671 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 671

Advancing to step 2:
The number 671 fits into 25 0 times, leaving a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 671

Going ahead to step 3:
When dividing 255 by 671, we get 0 with a remainder of 255.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 255 after subtracting 0 from 255.
Append the next digit (1) from the dividend to 255 and continue with: 2551 / 671

Let's proceed to step 4:
671 goes into 2551 3 times with a remainder of 538.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 2013 from 2551, we get 538.
Fetch the next digit (9) from the dividend, attach it to 538 and continue: 5389 / 671

Going ahead to step 5:
The number 671 fits into 5389 8 times, leaving a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Deduct 5368 from 5389 and we're left with 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 671

Advancing to step 6:
When dividing 211 by 671, we get 0 with a remainder of 211.
The next digit of our result is 0. 
Result so far: 380.0
Subtract 0 from 211 to get 211.
Bring next digit (7) of the dividend behind the 211 and repeat the process: 2117 / 671

Moving on to step 7:
When dividing 2117 by 671, we get 3 with a remainder of 104.
Put 3 as the next digit of the answer. 
Result so far: 3803.0
Subtract 2013 from 2117 to get 104.
Append the next digit (0) from the dividend to 104 and continue with: 1040 / 671

Step 8:
If we divide 1040 by 671, we get 1 and a remainder of 369.
Put 1 as the next digit of the answer. 
Result so far: 38031.0
Subtracting 671 from 1040 leaves us with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Advancing to step 9:
671 can be fit into 3690 5 times, resulting in a remainder of 335.
Write down 5 as next digit of the result. 
Result so far: 38031.5
Subtracting 3355 from 3690 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Going ahead to step 10:
If we divide 3350 by 671, we get 4 and a remainder of 666.
Record the quotient 4 as the next digit in the result. 
Result so far: 38031.54
If we subtract 2684 from 3350, we get 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Step 11:
The number 671 fits into 6660 9 times, leaving a remainder of 621.
Put 9 as the next digit of the answer. 
Result so far: 38031.549
If we subtract 6039 from 6660, we get 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

On to step 12:
If we divide 6210 by 671, we get 9 and a remainder of 171.
Use 9 as the next digit of our solution. 
Result so far: 38031.5499
If we subtract 6039 from 6210, we get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

In conclusion, the division gives 38031.5499 with a balance of 0.00171.
