68412 ÷ 89 
The aim is to understand the frequency of 89 in 68412.

Step 1:
6 divided by 89 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 89

On to step 2:
The number 89 fits into 68 0 times, leaving a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Include the next digit (4) from the dividend after 68, then repeat: 684 / 89

Going ahead to step 3:
If we divide 684 by 89, we get 7 and a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 623 from 684, we get 61.
Grab the next digit (1) from the dividend, add it to 61, then carry on: 611 / 89

Step 4:
The number 89 fits into 611 6 times, leaving a remainder of 77.
Put 6 as the next digit of the answer. 
Result so far: 76.0
The remainder is 77 after subtracting 534 from 611.
Fetch the next digit (2) from the dividend, attach it to 77 and continue: 772 / 89

Advancing to step 5:
89 can be fit into 772 8 times, resulting in a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 768.0
Subtracting 712 from 772 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.

Advancing to step 6:
89 goes into 600 6 times with a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 768.6
Subtracting 534 from 600 leaves us 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.

Advancing to step 7:
660 divided by 89 is 7 with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 768.67
Subtracting 623 from 660 leaves us 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.

Advancing to step 8:
When dividing 370 by 89, we get 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 768.674
The remainder is 14 after subtracting 356 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
89 goes into 140 1 times with a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 768.6741
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.

Moving on to step 10:
89 can be fit into 510 5 times, resulting in a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 768.67415
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.

Going ahead to step 11:
When dividing 650 by 89, we get 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 768.674157
Deduct 623 from 650 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 12:
89 can be fit into 270 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 768.6741573
The remainder is 3 after subtracting 267 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
When dividing 30 by 89, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 768.6741573
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 768.6741573, with a leftover of 3e-08.
