We're dividing 661036 by 89 
The aim is to understand the frequency of 89 in 661036.

On to step 1:
6 divided by 89 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 89

Going ahead to step 2:
66 divided by 89 is 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 89

Moving on to step 3:
661 divided by 89 is 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 623 from 661 to get 38.
Append the next digit (0) from the dividend to 38 and continue with: 380 / 89

Moving on to step 4:
When dividing 380 by 89, we get 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Subtract 356 from 380 to get 24.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 89

Let's proceed to step 5:
The number 89 fits into 243 2 times, leaving a remainder of 65.
The number 2 becomes the next digit in our result. 
Result so far: 742.0
Deduct 178 from 243 and we're left with 65.
Include the next digit (6) from the dividend after 65, then repeat: 656 / 89

Moving on to step 6:
89 can be fit into 656 7 times, resulting in a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 7427.0
The remainder is 33 after subtracting 623 from 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 7:
If we divide 330 by 89, we get 3 and a remainder of 63.
The next digit of our result is 3. 
Result so far: 7427.3
The remainder is 63 after subtracting 267 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 8:
89 can be fit into 630 7 times, resulting in a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 7427.37
Subtracting 623 from 630 leaves us 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.

On to step 9:
70 divided by 89 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 7427.37
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
When dividing 700 by 89, we get 7 with a remainder of 77.
Write down 7 as next digit of the result. 
Result so far: 7427.3707
Subtracting 623 from 700 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 11:
89 can be fit into 770 8 times, resulting in a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 7427.37078
Subtracting 712 from 770 leaves us with 58.
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 12:
If we divide 580 by 89, we get 6 and a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 7427.370786
Subtract 534 from 580 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 13:
The number 89 fits into 460 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 7427.3707865
If we subtract 445 from 460, we get 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 14:
89 can be fit into 150 1 times, resulting in a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 7427.37078651
If we subtract 89 from 150, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The quotient of the division is 7427.37078651, and the remainder is 6.1e-08.
