628170 divided by 89 
The aim is to understand the frequency of 89 in 628170.

On to step 1:
89 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 89

Going ahead to step 2:
The number 89 fits into 62 0 times, leaving a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 62 leaves us with 62.
Fetch the next digit (8) from the dividend, attach it to 62 and continue: 628 / 89

Moving on to step 3:
628 divided by 89 is 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 623 from 628 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 89

Let's proceed to step 4:
The number 89 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 70.0
Subtracting 0 from 51 leaves us with 51.
Append the next digit (7) from the dividend to 51 and continue with: 517 / 89

Moving on to step 5:
517 divided by 89 is 5 with a remainder of 72.
The number 5 becomes the next digit in our result. 
Result so far: 705.0
The remainder is 72 after subtracting 445 from 517.
Include the next digit (0) from the dividend after 72, then repeat: 720 / 89

Let's proceed to step 6:
89 can be fit into 720 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 7058.0
Subtract 712 from 720 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
If we divide 80 by 89, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 7058.0
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 8:
When dividing 800 by 89, we get 8 with a remainder of 88.
Put 8 as the next digit of the answer. 
Result so far: 7058.08
If we subtract 712 from 800, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 9:
If we divide 880 by 89, we get 9 and a remainder of 79.
The next digit of our result is 9. 
Result so far: 7058.089
If we take 801 away from 880, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 10:
89 goes into 790 8 times with a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 7058.0898
Subtracting 712 from 790 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 11:
The number 89 fits into 780 8 times, leaving a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 7058.08988
Subtract 712 from 780 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Our division results in 7058.08988 with a remaining 6.8e-05.
