We look at the division of 381273 by 89 
The aim is to understand the frequency of 89 in 381273.

On to step 1:
If we divide 3 by 89, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 89

Advancing to step 2:
89 goes into 38 0 times with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 89

Let's proceed to step 3:
The number 89 fits into 381 4 times, leaving a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 356 from 381 and we're left with 25.
Fetch the next digit (2) from the dividend, attach it to 25 and continue: 252 / 89

On to step 4:
When dividing 252 by 89, we get 2 with a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Subtracting 178 from 252 leaves us with 74.
Fetch the next digit (7) from the dividend, attach it to 74 and continue: 747 / 89

Advancing to step 5:
747 divided by 89 is 8 with a remainder of 35.
Write down 8 as next digit of the result. 
Result so far: 428.0
If we subtract 712 from 747, we get 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 89

Going ahead to step 6:
The number 89 fits into 353 3 times, leaving a remainder of 86.
Put 3 as the next digit of the answer. 
Result so far: 4283.0
The remainder is 86 after subtracting 267 from 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 7:
860 divided by 89 is 9 with a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 4283.9
If we subtract 801 from 860, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 8:
89 goes into 590 6 times with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 4283.96
Subtract 534 from 590 to 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.

On to step 9:
The number 89 fits into 560 6 times, leaving a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 4283.966
If we subtract 534 from 560, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 4283.966 with a remainder of 0.0026.
