We're dividing 986983 by 89 
The aim is to understand the frequency of 89 in 986983.

Step 1:
9 divided by 89 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 89

Moving on to step 2:
89 can be fit into 98 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 89 from 98, we get 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 89

Step 3:
If we divide 96 by 89, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 89 from 96 to get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 89

Step 4:
The number 89 fits into 79 0 times, leaving a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 110.0
Deduct 0 from 79 and we're left with 79.
Grab the next digit (8) from the dividend, add it to 79, then carry on: 798 / 89

Going ahead to step 5:
If we divide 798 by 89, we get 8 and a remainder of 86.
Put 8 as the next digit of the answer. 
Result so far: 1108.0
Deduct 712 from 798 and we're left with 86.
Grab the next digit (3) from the dividend, add it to 86, then carry on: 863 / 89

Step 6:
If we divide 863 by 89, we get 9 and a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 11089.0
Subtract 801 from 863 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 7:
89 goes into 620 6 times with a remainder of 86.
Put 6 as the next digit of the answer. 
Result so far: 11089.6
If we subtract 534 from 620, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 8:
89 goes into 860 9 times with a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 11089.69
If we take 801 away from 860, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 9:
When dividing 590 by 89, we get 6 with a remainder of 56.
The next digit of our result is 6. 
Result so far: 11089.696
If we subtract 534 from 590, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 10:
89 goes into 560 6 times with a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 11089.6966
If we take 534 away from 560, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 11089.6966 and a remainder of 0.00026.
