97529971 ÷ 689 
The aim is to understand the frequency of 689 in 97529971.

Advancing to step 1:
689 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 689

Step 2:
97 divided by 689 is 0 with a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 97 to get 97.
Append the next digit (5) from the dividend to 97 and continue with: 975 / 689

Let's proceed to step 3:
When dividing 975 by 689, we get 1 with a remainder of 286.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 689 from 975 leaves us with 286.
Grab the next digit (2) from the dividend, add it to 286, then carry on: 2862 / 689

Advancing to step 4:
When dividing 2862 by 689, we get 4 with a remainder of 106.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 2756 from 2862 leaves us with 106.
Bring next digit (9) of the dividend behind the 106 and repeat the process: 1069 / 689

Moving on to step 5:
1069 divided by 689 is 1 with a remainder of 380.
The next digit of our result is 1. 
Result so far: 141.0
Subtracting 689 from 1069 leaves us with 380.
Include the next digit (9) from the dividend after 380, then repeat: 3809 / 689

Let's proceed to step 6:
If we divide 3809 by 689, we get 5 and a remainder of 364.
Put 5 as the next digit of the answer. 
Result so far: 1415.0
If we subtract 3445 from 3809, we get 364.
Take the next digit (7) from the dividend and append it to 364, then repeat: 3647 / 689

On to step 7:
When dividing 3647 by 689, we get 5 with a remainder of 202.
Write down 5 as next digit of the result. 
Result so far: 14155.0
Deduct 3445 from 3647 and we're left with 202.
Include the next digit (1) from the dividend after 202, then repeat: 2021 / 689

Moving on to step 8:
The number 689 fits into 2021 2 times, leaving a remainder of 643.
The next digit of our result is 2. 
Result so far: 141552.0
Subtracting 1378 from 2021 leaves us with 643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

Advancing to step 9:
689 goes into 6430 9 times with a remainder of 229.
Record the quotient 9 as the next digit in the result. 
Result so far: 141552.9
Subtracting 6201 from 6430 leaves us with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Let's proceed to step 10:
The number 689 fits into 2290 3 times, leaving a remainder of 223.
The next digit of our result is 3. 
Result so far: 141552.93
Subtract 2067 from 2290 to get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

On to step 11:
When dividing 2230 by 689, we get 3 with a remainder of 163.
Record the quotient 3 as the next digit in the result. 
Result so far: 141552.933
If we take 2067 away from 2230, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

The quotient of the division is 141552.933, and the remainder is 0.0163.
