We look at the division of 879647 by 89 
The aim is to understand the frequency of 89 in 879647.

Let's proceed to step 1:
If we divide 8 by 89, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 89

Moving on to step 2:
89 goes into 87 0 times with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Append the next digit (9) from the dividend to 87 and continue with: 879 / 89

Going ahead to step 3:
89 can be fit into 879 9 times, resulting in a remainder of 78.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 801 from 879 and we're left with 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 89

Let's proceed to step 4:
When dividing 786 by 89, we get 8 with a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 98.0
Subtracting 712 from 786 leaves us with 74.
Fetch the next digit (4) from the dividend, attach it to 74 and continue: 744 / 89

Let's proceed to step 5:
When dividing 744 by 89, we get 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 988.0
If we take 712 away from 744, we end up with 32.
Include the next digit (7) from the dividend after 32, then repeat: 327 / 89

Moving on to step 6:
If we divide 327 by 89, we get 3 and a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 9883.0
Subtracting 267 from 327 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.

Moving on to step 7:
89 goes into 600 6 times with a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 9883.6
If we subtract 534 from 600, we 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.
Write down 7 as next digit of the result. 
Result so far: 9883.67
The remainder is 37 after subtracting 623 from 660.
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 9:
The number 89 fits into 370 4 times, leaving a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 9883.674
If we take 356 away from 370, we end up 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.

Let's proceed to step 10:
If we divide 140 by 89, we get 1 and a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 9883.6741
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.

Step 11:
510 divided by 89 is 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 9883.67415
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 12:
650 divided by 89 is 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 9883.674157
If we take 623 away from 650, we end up 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 13:
89 can be fit into 270 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 9883.6741573
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.

Advancing to step 14:
If we divide 30 by 89, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 9883.6741573
Subtract 0 from 30 to get 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 result is 9883.6741573 with a remainder of 3e-08.
