We're dividing 622710 by 89 
The aim is to understand the frequency of 89 in 622710.

Step 1:
When dividing 6 by 89, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 89

Going ahead to step 2:
89 can be fit into 62 0 times, resulting in a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Include the next digit (2) from the dividend after 62, then repeat: 622 / 89

Let's proceed to step 3:
When dividing 622 by 89, we get 6 with a remainder of 88.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 534 away from 622, we end up with 88.
Include the next digit (7) from the dividend after 88, then repeat: 887 / 89

Advancing to step 4:
89 can be fit into 887 9 times, resulting in a remainder of 86.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Subtract 801 from 887 to get 86.
Include the next digit (1) from the dividend after 86, then repeat: 861 / 89

Let's proceed to step 5:
89 goes into 861 9 times with a remainder of 60.
Use 9 as the next digit of our solution. 
Result so far: 699.0
The remainder is 60 after subtracting 801 from 861.
Grab the next digit (0) from the dividend, add it to 60, then carry on: 600 / 89

Step 6:
If we divide 600 by 89, we get 6 and a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 6996.0
Subtracting 534 from 600 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 7:
The number 89 fits into 660 7 times, leaving a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 6996.7
If we take 623 away from 660, we end up with 37.
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 8:
If we divide 370 by 89, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 6996.74
Subtract 356 from 370 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
89 goes into 140 1 times with a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 6996.741
Subtracting 89 from 140 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 10:
89 goes into 510 5 times with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 6996.7415
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.

Step 11:
The number 89 fits into 650 7 times, leaving a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 6996.74157
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.

Moving on to step 12:
If we divide 270 by 89, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 6996.741573
Deduct 267 from 270 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
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: 6996.741573
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.

Let's proceed to step 14:
89 can be fit into 300 3 times, resulting in a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 6996.74157303
Deduct 267 from 300 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final outcome is 6996.74157303, with a leftover of 3.3e-08.
