We look at the division of 173800 by 89 
The aim is to understand the frequency of 89 in 173800.

Let's proceed to step 1:
1 divided by 89 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 89

Going ahead to step 2:
The number 89 fits into 17 0 times, leaving a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 89

Let's proceed to step 3:
89 can be fit into 173 1 times, resulting in a remainder of 84.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 89 from 173 and we're left with 84.
Append the next digit (8) from the dividend to 84 and continue with: 848 / 89

Step 4:
89 goes into 848 9 times with a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we take 801 away from 848, we end up with 47.
Append the next digit (0) from the dividend to 47 and continue with: 470 / 89

Let's proceed to step 5:
If we divide 470 by 89, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 195.0
Deduct 445 from 470 and we're left with 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 89

Let's proceed to step 6:
When dividing 250 by 89, we get 2 with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 1952.0
Subtracting 178 from 250 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 7:
If we divide 720 by 89, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 1952.8
If we subtract 712 from 720, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
When dividing 80 by 89, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 1952.8
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 9:
The number 89 fits into 800 8 times, leaving a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 1952.808
If we subtract 712 from 800, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 10:
If we divide 880 by 89, we get 9 and a remainder of 79.
The number 9 becomes the next digit in our result. 
Result so far: 1952.8089
Subtracting 801 from 880 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 11:
If we divide 790 by 89, we get 8 and a remainder of 78.
Write down 8 as next digit of the result. 
Result so far: 1952.80898
Subtract 712 from 790 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 12:
89 can be fit into 780 8 times, resulting in a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 1952.808988
The remainder is 68 after subtracting 712 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final outcome is 1952.808988, with a leftover of 6.8e-06.
