We divide 691323 by 89
The aim is to understand the frequency of 89 in 691323.

Advancing to step 1:
If we divide 6 by 89, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 89

Advancing to step 2:
When dividing 69 by 89, we get 0 with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 69 to get 69.
Include the next digit (1) from the dividend after 69, then repeat: 691 / 89

Let's proceed to step 3:
89 goes into 691 7 times with a remainder of 68.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 623 from 691, we get 68.
Fetch the next digit (3) from the dividend, attach it to 68 and continue: 683 / 89

Step 4:
When dividing 683 by 89, we get 7 with a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
The remainder is 60 after subtracting 623 from 683.
Take the next digit (2) from the dividend and append it to 60, then repeat: 602 / 89

On to step 5:
The number 89 fits into 602 6 times, leaving a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 776.0
Subtracting 534 from 602 leaves us with 68.
Include the next digit (3) from the dividend after 68, then repeat: 683 / 89

Going ahead to step 6:
89 goes into 683 7 times with a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 7767.0
Subtract 623 from 683 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 7:
89 can be fit into 600 6 times, resulting in a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 7767.6
Subtract 534 from 600 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 8:
The number 89 fits into 660 7 times, leaving a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 7767.67
The remainder is 37 after subtracting 623 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 9:
The number 89 fits into 370 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 7767.674
The remainder is 14 after subtracting 356 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
140 divided by 89 is 1 with a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 7767.6741
Subtract 89 from 140 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 11:
When dividing 510 by 89, we get 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 7767.67415
If we subtract 445 from 510, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 12:
When dividing 650 by 89, we get 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 7767.674157
Subtracting 623 from 650 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 13:
The number 89 fits into 270 3 times, leaving a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 7767.6741573
The remainder is 3 after subtracting 267 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 14:
89 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 7767.6741573
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 7767.6741573, with a leftover of 3e-08.
