89612681 ÷ 485 
The aim is to understand the frequency of 485 in 89612681.

Advancing to step 1:
When dividing 8 by 485, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 485

Step 2:
485 can be fit into 89 0 times, resulting in a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Take the next digit (6) from the dividend and append it to 89, then repeat: 896 / 485

Step 3:
896 divided by 485 is 1 with a remainder of 411.
The next digit of our result is 1. 
Result so far: 1.0
If we take 485 away from 896, we end up with 411.
Bring next digit (1) of the dividend behind the 411 and repeat the process: 4111 / 485

Step 4:
If we divide 4111 by 485, we get 8 and a remainder of 231.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Deduct 3880 from 4111 and we're left with 231.
Append the next digit (2) from the dividend to 231 and continue with: 2312 / 485

On to step 5:
2312 divided by 485 is 4 with a remainder of 372.
Put 4 as the next digit of the answer. 
Result so far: 184.0
Deduct 1940 from 2312 and we're left with 372.
Bring next digit (6) of the dividend behind the 372 and repeat the process: 3726 / 485

On to step 6:
If we divide 3726 by 485, we get 7 and a remainder of 331.
The next digit of our result is 7. 
Result so far: 1847.0
If we take 3395 away from 3726, we end up with 331.
Fetch the next digit (8) from the dividend, attach it to 331 and continue: 3318 / 485

Going ahead to step 7:
When dividing 3318 by 485, we get 6 with a remainder of 408.
Record the quotient 6 as the next digit in the result. 
Result so far: 18476.0
Subtracting 2910 from 3318 leaves us with 408.
Include the next digit (1) from the dividend after 408, then repeat: 4081 / 485

Let's proceed to step 8:
The number 485 fits into 4081 8 times, leaving a remainder of 201.
Write down 8 as next digit of the result. 
Result so far: 184768.0
Subtracting 3880 from 4081 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Let's proceed to step 9:
When dividing 2010 by 485, we get 4 with a remainder of 70.
The number 4 becomes the next digit in our result. 
Result so far: 184768.4
If we subtract 1940 from 2010, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
485 goes into 700 1 times with a remainder of 215.
Put 1 as the next digit of the answer. 
Result so far: 184768.41
If we take 485 away from 700, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 11:
When dividing 2150 by 485, we get 4 with a remainder of 210.
Put 4 as the next digit of the answer. 
Result so far: 184768.414
Subtracting 1940 from 2150 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 12:
485 goes into 2100 4 times with a remainder of 160.
The number 4 becomes the next digit in our result. 
Result so far: 184768.4144
Subtracting 1940 from 2100 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The quotient of the division is 184768.4144, and the remainder is 0.0016.
