Let's divide 570820 by 89
The aim is to understand the frequency of 89 in 570820.

On to step 1:
89 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 89

Moving on to step 2:
The number 89 fits into 57 0 times, leaving a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Take the next digit (0) from the dividend and append it to 57, then repeat: 570 / 89

Advancing to step 3:
89 goes into 570 6 times with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 534 from 570 to get 36.
Take the next digit (8) from the dividend and append it to 36, then repeat: 368 / 89

On to step 4:
89 goes into 368 4 times with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
The remainder is 12 after subtracting 356 from 368.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 89

Moving on to step 5:
If we divide 122 by 89, we get 1 and a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 641.0
Subtract 89 from 122 to get 33.
Take the next digit (0) from the dividend and append it to 33, then repeat: 330 / 89

Going ahead to step 6:
The number 89 fits into 330 3 times, leaving a remainder of 63.
The next digit of our result is 3. 
Result so far: 6413.0
Subtract 267 from 330 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 7:
When dividing 630 by 89, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 6413.7
If we take 623 away from 630, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
89 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 6413.7
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 9:
700 divided by 89 is 7 with a remainder of 77.
The next digit of our result is 7. 
Result so far: 6413.707
If we subtract 623 from 700, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 10:
89 goes into 770 8 times with a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 6413.7078
The remainder is 58 after subtracting 712 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 11:
If we divide 580 by 89, we get 6 and a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 6413.70786
The remainder is 46 after subtracting 534 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
89 goes into 460 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 6413.707865
Subtracting 445 from 460 leaves us 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.

Let's proceed to step 13:
When dividing 150 by 89, we get 1 with a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 6413.7078651
The remainder is 61 after subtracting 89 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 14:
The number 89 fits into 610 6 times, leaving a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 6413.70786516
Deduct 534 from 610 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

In conclusion, the division gives 6413.70786516 with a balance of 7.6e-08.
