We divide 85624 by 89
The aim is to understand the frequency of 89 in 85624.

On to step 1:
8 divided by 89 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 89

Going ahead to step 2:
When dividing 85 by 89, we get 0 with a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Bring next digit (6) of the dividend behind the 85 and repeat the process: 856 / 89

Advancing to step 3:
The number 89 fits into 856 9 times, leaving a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 801 from 856 leaves us with 55.
Bring next digit (2) of the dividend behind the 55 and repeat the process: 552 / 89

Moving on to step 4:
89 can be fit into 552 6 times, resulting in a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 96.0
The remainder is 18 after subtracting 534 from 552.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 89

Advancing to step 5:
If we divide 184 by 89, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 962.0
The remainder is 6 after subtracting 178 from 184.
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 6:
60 divided by 89 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 962.0
Subtracting 0 from 60 leaves us with 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 7:
When dividing 600 by 89, we get 6 with a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 962.06
Subtract 534 from 600 to get 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 8:
660 divided by 89 is 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 962.067
Deduct 623 from 660 and we're left with 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 9:
89 goes into 370 4 times with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 962.0674
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 10:
If we divide 140 by 89, we get 1 and a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 962.06741
Subtracting 89 from 140 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 11:
The number 89 fits into 510 5 times, leaving a remainder of 65.
The next digit of our result is 5. 
Result so far: 962.067415
Subtracting 445 from 510 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 12:
If we divide 650 by 89, we get 7 and a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 962.0674157
If we subtract 623 from 650, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 13:
89 can be fit into 270 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 962.06741573
Subtracting 267 from 270 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 962.06741573 and a remainder of 3e-09.
