749209 divided by 84 
The aim is to understand the frequency of 84 in 749209.

Let's proceed to step 1:
7 divided by 84 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 84

Advancing to step 2:
74 divided by 84 is 0 with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Include the next digit (9) from the dividend after 74, then repeat: 749 / 84

Moving on to step 3:
749 divided by 84 is 8 with a remainder of 77.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 672 away from 749, we end up with 77.
Take the next digit (2) from the dividend and append it to 77, then repeat: 772 / 84

Step 4:
772 divided by 84 is 9 with a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 89.0
If we subtract 756 from 772, we get 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 84

Moving on to step 5:
160 divided by 84 is 1 with a remainder of 76.
The next digit of our result is 1. 
Result so far: 891.0
The remainder is 76 after subtracting 84 from 160.
Bring next digit (9) of the dividend behind the 76 and repeat the process: 769 / 84

Moving on to step 6:
84 goes into 769 9 times with a remainder of 13.
The next digit of our result is 9. 
Result so far: 8919.0
Deduct 756 from 769 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
84 goes into 130 1 times with a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 8919.1
Subtract 84 from 130 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 8:
When dividing 460 by 84, we get 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 8919.15
The remainder is 40 after subtracting 420 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
The number 84 fits into 400 4 times, leaving a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 8919.154
The remainder is 64 after subtracting 336 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
84 goes into 640 7 times with a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 8919.1547
Deduct 588 from 640 and we're left 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 11:
If we divide 520 by 84, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 8919.15476
If we take 504 away from 520, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
84 can be fit into 160 1 times, resulting in a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 8919.154761
Deduct 84 from 160 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 13:
The number 84 fits into 760 9 times, leaving a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 8919.1547619
If we subtract 756 from 760, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
84 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 8919.1547619
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 8919.1547619 with a balance of 4e-08.
