285464 divided by 89 
The aim is to understand the frequency of 89 in 285464.

On to step 1:
When dividing 2 by 89, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 89

Advancing to step 2:
89 goes into 28 0 times with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 89

Advancing to step 3:
89 can be fit into 285 3 times, resulting in a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 267 from 285 to get 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 89

On to step 4:
The number 89 fits into 184 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Deduct 178 from 184 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 89

On to step 5:
If we divide 66 by 89, we get 0 and a remainder of 66.
The next digit of our result is 0. 
Result so far: 320.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 89

On to step 6:
89 goes into 664 7 times with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 3207.0
The remainder is 41 after subtracting 623 from 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 7:
If we divide 410 by 89, we get 4 and a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 3207.4
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.

Advancing to step 8:
89 can be fit into 540 6 times, resulting in a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 3207.46
Subtracting 534 from 540 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
When dividing 60 by 89, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 3207.46
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
600 divided by 89 is 6 with a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 3207.4606
Deduct 534 from 600 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 11:
660 divided by 89 is 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 3207.46067
Subtract 623 from 660 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
89 can be fit into 370 4 times, resulting in a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 3207.460674
Subtracting 356 from 370 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
If we divide 140 by 89, we get 1 and a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 3207.4606741
If we subtract 89 from 140, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 14:
If we divide 510 by 89, we get 5 and a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 3207.46067415
Subtract 445 from 510 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 3207.46067415 and a remainder of 6.5e-08.
