689441 ÷ 84 
The aim is to understand the frequency of 84 in 689441.

Advancing to step 1:
The number 84 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 84

Advancing to step 2:
84 goes into 68 0 times with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Take the next digit (9) from the dividend and append it to 68, then repeat: 689 / 84

Step 3:
84 can be fit into 689 8 times, resulting in a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 672 away from 689, we end up with 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 84

Going ahead to step 4:
When dividing 174 by 84, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Subtracting 168 from 174 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 84

Let's proceed to step 5:
64 divided by 84 is 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 820.0
If we take 0 away from 64, we end up with 64.
Fetch the next digit (1) from the dividend, attach it to 64 and continue: 641 / 84

Let's proceed to step 6:
The number 84 fits into 641 7 times, leaving a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 8207.0
Deduct 588 from 641 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 7:
84 goes into 530 6 times with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 8207.6
If we subtract 504 from 530, 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.

Going ahead to step 8:
84 can be fit into 260 3 times, resulting in a remainder of 8.
The next digit of our result is 3. 
Result so far: 8207.63
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
84 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 8207.63
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
84 goes into 800 9 times with a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 8207.6309
The remainder is 44 after subtracting 756 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
84 goes into 440 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 8207.63095
Subtracting 420 from 440 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
The number 84 fits into 200 2 times, leaving a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 8207.630952
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
320 divided by 84 is 3 with a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 8207.6309523
Subtract 252 from 320 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 14:
When dividing 680 by 84, we get 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 8207.63095238
If we subtract 672 from 680, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 8207.63095238 and a remainder of 8e-09.
