Let's divide 751407 by 84
The aim is to understand the frequency of 84 in 751407.

Going ahead to step 1:
84 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 84

Going ahead to step 2:
84 can be fit into 75 0 times, resulting in a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Bring next digit (1) of the dividend behind the 75 and repeat the process: 751 / 84

On to step 3:
If we divide 751 by 84, we get 8 and a remainder of 79.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 672 from 751 and we're left with 79.
Append the next digit (4) from the dividend to 79 and continue with: 794 / 84

Step 4:
If we divide 794 by 84, we get 9 and a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 89.0
Subtracting 756 from 794 leaves us with 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 84

Moving on to step 5:
If we divide 380 by 84, we get 4 and a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 894.0
If we subtract 336 from 380, we get 44.
Take the next digit (7) from the dividend and append it to 44, then repeat: 447 / 84

Let's proceed to step 6:
When dividing 447 by 84, we get 5 with a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 8945.0
Deduct 420 from 447 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
270 divided by 84 is 3 with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 8945.3
Subtracting 252 from 270 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
84 goes into 180 2 times with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 8945.32
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
If we divide 120 by 84, we get 1 and a remainder of 36.
The next digit of our result is 1. 
Result so far: 8945.321
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
84 goes into 360 4 times with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 8945.3214
If we subtract 336 from 360, 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.

Advancing to step 11:
240 divided by 84 is 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 8945.32142
Subtracting 168 from 240 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
When dividing 720 by 84, we get 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 8945.321428
If we take 672 away from 720, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
480 divided by 84 is 5 with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 8945.3214285
Subtract 420 from 480 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
600 divided by 84 is 7 with a remainder of 12.
The next digit of our result is 7. 
Result so far: 8945.32142857
Subtracting 588 from 600 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 8945.32142857 with a balance of 1.2e-08.
