146985 ÷ 89 
The aim is to understand the frequency of 89 in 146985.

On to step 1:
1 divided by 89 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 89

Let's proceed to step 2:
14 divided by 89 is 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 89

Let's proceed to step 3:
The number 89 fits into 146 1 times, leaving a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 89 away from 146, we end up with 57.
Bring next digit (9) of the dividend behind the 57 and repeat the process: 579 / 89

Let's proceed to step 4:
If we divide 579 by 89, we get 6 and a remainder of 45.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 534 from 579 and we're left with 45.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 89

Moving on to step 5:
458 divided by 89 is 5 with a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 165.0
Subtracting 445 from 458 leaves us with 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 89

On to step 6:
89 goes into 135 1 times with a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 1651.0
Subtracting 89 from 135 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 7:
460 divided by 89 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1651.5
The remainder is 15 after subtracting 445 from 460.
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 8:
The number 89 fits into 150 1 times, leaving a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 1651.51
The remainder is 61 after subtracting 89 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 9:
When dividing 610 by 89, we get 6 with a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 1651.516
If we subtract 534 from 610, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
760 divided by 89 is 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 1651.5168
Subtract 712 from 760 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
When dividing 480 by 89, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 1651.51685
Subtract 445 from 480 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 12:
If we divide 350 by 89, we get 3 and a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 1651.516853
The remainder is 83 after subtracting 267 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 13:
830 divided by 89 is 9 with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 1651.5168539
The remainder is 29 after subtracting 801 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 14:
If we divide 290 by 89, we get 3 and a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 1651.51685393
The remainder is 23 after subtracting 267 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

In conclusion, the division gives 1651.51685393 with a balance of 2.3e-08.
