We're dividing 618090 by 89 
The aim is to understand the frequency of 89 in 618090.

Going ahead to step 1:
The number 89 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 89

Going ahead to step 2:
61 divided by 89 is 0 with a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Append the next digit (8) from the dividend to 61 and continue with: 618 / 89

Let's proceed to step 3:
89 goes into 618 6 times with a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 534 from 618 leaves us with 84.
Grab the next digit (0) from the dividend, add it to 84, then carry on: 840 / 89

Step 4:
89 can be fit into 840 9 times, resulting in a remainder of 39.
The next digit of our result is 9. 
Result so far: 69.0
If we subtract 801 from 840, we get 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 89

Step 5:
399 divided by 89 is 4 with a remainder of 43.
Record the quotient 4 as the next digit in the result. 
Result so far: 694.0
If we subtract 356 from 399, we get 43.
Grab the next digit (0) from the dividend, add it to 43, then carry on: 430 / 89

Moving on to step 6:
The number 89 fits into 430 4 times, leaving a remainder of 74.
The next digit of our result is 4. 
Result so far: 6944.0
Subtracting 356 from 430 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 7:
The number 89 fits into 740 8 times, leaving a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 6944.8
Subtract 712 from 740 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
89 goes into 280 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 6944.83
The remainder is 13 after subtracting 267 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
The number 89 fits into 130 1 times, leaving a remainder of 41.
The next digit of our result is 1. 
Result so far: 6944.831
Subtract 89 from 130 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 10:
The number 89 fits into 410 4 times, leaving a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 6944.8314
If we subtract 356 from 410, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 11:
The number 89 fits into 540 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 6944.83146
Deduct 534 from 540 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
89 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 6944.83146
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 13:
89 goes into 600 6 times with a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 6944.8314606
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.

On to step 14:
89 goes into 660 7 times with a remainder of 37.
The next digit of our result is 7. 
Result so far: 6944.83146067
Subtracting 623 from 660 leaves us 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.

After the division, we end up with 6944.83146067 and a remainder of 3.7e-08.
