65670 divided by 89 
The aim is to understand the frequency of 89 in 65670.

Step 1:
When dividing 6 by 89, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 89

Step 2:
The number 89 fits into 65 0 times, leaving a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Include the next digit (6) from the dividend after 65, then repeat: 656 / 89

On to step 3:
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: 7.0
Deduct 623 from 656 and we're left with 33.
Take the next digit (7) from the dividend and append it to 33, then repeat: 337 / 89

Advancing to step 4:
337 divided by 89 is 3 with a remainder of 70.
Write down 3 as next digit of the result. 
Result so far: 73.0
The remainder is 70 after subtracting 267 from 337.
Fetch the next digit (0) from the dividend, attach it to 70 and continue: 700 / 89

On to step 5:
If we divide 700 by 89, we get 7 and a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 737.0
If we take 623 away from 700, we end up 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.

Let's proceed to step 6:
89 can be fit into 770 8 times, resulting in a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 737.8
The remainder is 58 after subtracting 712 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 7:
89 goes into 580 6 times with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 737.86
Deduct 534 from 580 and we're left 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 8:
89 can be fit into 460 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 737.865
If we take 445 away from 460, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
When dividing 150 by 89, we get 1 with a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 737.8651
Subtract 89 from 150 to 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.

Going ahead to step 10:
89 can be fit into 610 6 times, resulting in a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 737.86516
The remainder is 76 after subtracting 534 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 11:
89 can be fit into 760 8 times, resulting in a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 737.865168
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.

Moving on to step 12:
When dividing 480 by 89, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 737.8651685
If we subtract 445 from 480, we 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.

Let's proceed to step 13:
350 divided by 89 is 3 with a remainder of 83.
Write down 3 as next digit of the result. 
Result so far: 737.86516853
Subtract 267 from 350 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

The final result is 737.86516853 with a remainder of 8.3e-08.
