We're dividing 916520 by 84 
The aim is to understand the frequency of 84 in 916520.

Moving on to step 1:
9 divided by 84 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 84

Step 2:
If we divide 91 by 84, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 84 from 91 and we're left with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 84

Advancing to step 3:
84 can be fit into 76 0 times, resulting in a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 76, we get 76.
Append the next digit (5) from the dividend to 76 and continue with: 765 / 84

Moving on to step 4:
765 divided by 84 is 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 109.0
Subtract 756 from 765 to get 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 84

Going ahead to step 5:
If we divide 92 by 84, we get 1 and a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1091.0
Deduct 84 from 92 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 84

Let's proceed to step 6:
80 divided by 84 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 10910.0
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 7:
84 goes into 800 9 times with a remainder of 44.
The next digit of our result is 9. 
Result so far: 10910.9
If we take 756 away from 800, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 8:
440 divided by 84 is 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 10910.95
Subtract 420 from 440 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
The number 84 fits into 200 2 times, leaving a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 10910.952
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
When dividing 320 by 84, we get 3 with a remainder of 68.
The next digit of our result is 3. 
Result so far: 10910.9523
If we take 252 away from 320, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 11:
84 can be fit into 680 8 times, resulting in a remainder of 8.
The next digit of our result is 8. 
Result so far: 10910.95238
Deduct 672 from 680 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
The number 84 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 10910.95238
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
800 divided by 84 is 9 with a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 10910.9523809
Subtract 756 from 800 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 14:
440 divided by 84 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 10910.95238095
If we take 420 away from 440, we end up 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.

In conclusion, the division gives 10910.95238095 with a balance of 2e-08.
