We're dividing 6578661 by 889 
The aim is to understand the frequency of 889 in 6578661.

Advancing to step 1:
889 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 889

Let's proceed to step 2:
If we divide 65 by 889, we get 0 and a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Append the next digit (7) from the dividend to 65 and continue with: 657 / 889

Let's proceed to step 3:
If we divide 657 by 889, we get 0 and a remainder of 657.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 657 to get 657.
Include the next digit (8) from the dividend after 657, then repeat: 6578 / 889

Going ahead to step 4:
889 can be fit into 6578 7 times, resulting in a remainder of 355.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 6223 from 6578 leaves us with 355.
Take the next digit (6) from the dividend and append it to 355, then repeat: 3556 / 889

Going ahead to step 5:
When dividing 3556 by 889, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 74.0
Subtracting 3556 from 3556 leaves us with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 889

Step 6:
When dividing 6 by 889, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 740.0
If we take 0 away from 6, we end up with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 889

Let's proceed to step 7:
If we divide 61 by 889, we get 0 and a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 7400.0
If we take 0 away from 61, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 8:
When dividing 610 by 889, we get 0 with a remainder of 610.
Record the quotient 0 as the next digit in the result. 
Result so far: 7400.0
Subtract 0 from 610 to get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

On to step 9:
When dividing 6100 by 889, we get 6 with a remainder of 766.
Record the quotient 6 as the next digit in the result. 
Result so far: 7400.06
Subtract 5334 from 6100 to get 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

Let's proceed to step 10:
If we divide 7660 by 889, we get 8 and a remainder of 548.
The number 8 becomes the next digit in our result. 
Result so far: 7400.068
If we take 7112 away from 7660, we end up with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Advancing to step 11:
If we divide 5480 by 889, we get 6 and a remainder of 146.
The next digit of our result is 6. 
Result so far: 7400.0686
Subtracting 5334 from 5480 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 12:
1460 divided by 889 is 1 with a remainder of 571.
Write down 1 as next digit of the result. 
Result so far: 7400.06861
If we take 889 away from 1460, we end up with 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

On to step 13:
5710 divided by 889 is 6 with a remainder of 376.
Record the quotient 6 as the next digit in the result. 
Result so far: 7400.068616
If we take 5334 away from 5710, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 14:
889 goes into 3760 4 times with a remainder of 204.
The next digit of our result is 4. 
Result so far: 7400.0686164
Deduct 3556 from 3760 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 15:
When dividing 2040 by 889, we get 2 with a remainder of 262.
Put 2 as the next digit of the answer. 
Result so far: 7400.06861642
Deduct 1778 from 2040 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

In conclusion, the division gives 7400.06861642 with a balance of 2.62e-07.
