897915 ÷ 89 
The aim is to understand the frequency of 89 in 897915.

Step 1:
If we divide 8 by 89, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 89

Advancing to step 2:
89 goes into 89 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 0 after subtracting 89 from 89.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 89

Let's proceed to step 3:
The number 89 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 89

Moving on to step 4:
89 goes into 79 0 times with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 100.0
The remainder is 79 after subtracting 0 from 79.
Append the next digit (1) from the dividend to 79 and continue with: 791 / 89

On to step 5:
791 divided by 89 is 8 with a remainder of 79.
Put 8 as the next digit of the answer. 
Result so far: 1008.0
If we take 712 away from 791, we end up with 79.
Take the next digit (5) from the dividend and append it to 79, then repeat: 795 / 89

Let's proceed to step 6:
When dividing 795 by 89, we get 8 with a remainder of 83.
Put 8 as the next digit of the answer. 
Result so far: 10088.0
The remainder is 83 after subtracting 712 from 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 7:
The number 89 fits into 830 9 times, leaving a remainder of 29.
The next digit of our result is 9. 
Result so far: 10088.9
Subtract 801 from 830 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 8:
The number 89 fits into 290 3 times, leaving a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 10088.93
Deduct 267 from 290 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 9:
If we divide 230 by 89, we get 2 and a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 10088.932
If we take 178 away from 230, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
When dividing 520 by 89, we get 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 10088.9325
Deduct 445 from 520 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 11:
750 divided by 89 is 8 with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 10088.93258
Deduct 712 from 750 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
89 goes into 380 4 times with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 10088.932584
If we subtract 356 from 380, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
The number 89 fits into 240 2 times, leaving a remainder of 62.
The next digit of our result is 2. 
Result so far: 10088.9325842
If we subtract 178 from 240, we 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.

Let's proceed to step 14:
The number 89 fits into 620 6 times, leaving a remainder of 86.
The next digit of our result is 6. 
Result so far: 10088.93258426
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.

The quotient of the division is 10088.93258426, and the remainder is 8.6e-08.
