We look at the division of 52499483 by 89 
The aim is to understand the frequency of 89 in 52499483.

Let's proceed to step 1:
The number 89 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 89

Advancing to step 2:
When dividing 52 by 89, we get 0 with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Bring next digit (4) of the dividend behind the 52 and repeat the process: 524 / 89

Going ahead to step 3:
89 goes into 524 5 times with a remainder of 79.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 445 from 524 leaves us with 79.
Append the next digit (9) from the dividend to 79 and continue with: 799 / 89

Step 4:
If we divide 799 by 89, we get 8 and a remainder of 87.
The next digit of our result is 8. 
Result so far: 58.0
If we subtract 712 from 799, we get 87.
Grab the next digit (9) from the dividend, add it to 87, then carry on: 879 / 89

Advancing to step 5:
879 divided by 89 is 9 with a remainder of 78.
Write down 9 as next digit of the result. 
Result so far: 589.0
The remainder is 78 after subtracting 801 from 879.
Take the next digit (4) from the dividend and append it to 78, then repeat: 784 / 89

Advancing to step 6:
89 goes into 784 8 times with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 5898.0
Deduct 712 from 784 and we're left with 72.
Fetch the next digit (8) from the dividend, attach it to 72 and continue: 728 / 89

Let's proceed to step 7:
89 goes into 728 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 58988.0
Subtract 712 from 728 to get 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 89

On to step 8:
163 divided by 89 is 1 with a remainder of 74.
Record the quotient 1 as the next digit in the result. 
Result so far: 589881.0
Subtracting 89 from 163 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.

Going ahead to step 9:
89 can be fit into 740 8 times, resulting in a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 589881.8
If we take 712 away from 740, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
When dividing 280 by 89, we get 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 589881.83
Deduct 267 from 280 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 11:
89 goes into 130 1 times with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 589881.831
The remainder is 41 after subtracting 89 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 12:
89 can be fit into 410 4 times, resulting in a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 589881.8314
The remainder is 54 after subtracting 356 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 13:
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: 589881.83146
The remainder is 6 after subtracting 534 from 540.
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 14:
The number 89 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 589881.83146
Deduct 0 from 60 and we're left 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.

Moving on to step 15:
89 can be fit into 600 6 times, resulting in a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 589881.8314606
If we subtract 534 from 600, we 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 16:
If we divide 660 by 89, we get 7 and a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 589881.83146067
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.

The final result is 589881.83146067 with a remainder of 3.7e-08.
