We look at the division of 678492 by 89 
The aim is to understand the frequency of 89 in 678492.

Moving on to 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.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 89

Let's proceed to step 2:
When dividing 67 by 89, we get 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Grab the next digit (8) from the dividend, add it to 67, then carry on: 678 / 89

Step 3:
If we divide 678 by 89, we get 7 and a remainder of 55.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 623 from 678, we get 55.
Bring next digit (4) of the dividend behind the 55 and repeat the process: 554 / 89

Let's proceed to step 4:
If we divide 554 by 89, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 76.0
If we take 534 away from 554, we end up with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 89

Advancing to step 5:
When dividing 209 by 89, we get 2 with a remainder of 31.
Record the quotient 2 as the next digit in the result. 
Result so far: 762.0
Subtract 178 from 209 to get 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 89

Moving on to step 6:
89 goes into 312 3 times with a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 7623.0
Subtract 267 from 312 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
When dividing 450 by 89, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 7623.5
The remainder is 5 after subtracting 445 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
When dividing 50 by 89, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 7623.5
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
If we divide 500 by 89, we get 5 and a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 7623.505
If we take 445 away from 500, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 10:
89 can be fit into 550 6 times, resulting in a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 7623.5056
The remainder is 16 after subtracting 534 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
If we divide 160 by 89, we get 1 and a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 7623.50561
Subtract 89 from 160 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 12:
When dividing 710 by 89, we get 7 with a remainder of 87.
The next digit of our result is 7. 
Result so far: 7623.505617
If we take 623 away from 710, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 13:
870 divided by 89 is 9 with a remainder of 69.
The next digit of our result is 9. 
Result so far: 7623.5056179
Subtract 801 from 870 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 14:
If we divide 690 by 89, we get 7 and a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 7623.50561797
If we take 623 away from 690, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The final outcome is 7623.50561797, with a leftover of 6.7e-08.
