We're dividing 758391 by 84 
The aim is to understand the frequency of 84 in 758391.

Moving on to step 1:
84 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 84

Let's proceed to step 2:
84 goes into 75 0 times with a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Grab the next digit (8) from the dividend, add it to 75, then carry on: 758 / 84

Step 3:
The number 84 fits into 758 9 times, leaving a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 756 from 758 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 84

Going ahead to step 4:
23 divided by 84 is 0 with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Subtract 0 from 23 to get 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 84

On to step 5:
The number 84 fits into 239 2 times, leaving a remainder of 71.
The number 2 becomes the next digit in our result. 
Result so far: 902.0
Deduct 168 from 239 and we're left with 71.
Take the next digit (1) from the dividend and append it to 71, then repeat: 711 / 84

Moving on to step 6:
84 goes into 711 8 times with a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 9028.0
If we take 672 away from 711, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 7:
The number 84 fits into 390 4 times, leaving a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 9028.4
The remainder is 54 after subtracting 336 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 8:
540 divided by 84 is 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 9028.46
If we take 504 away from 540, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
When dividing 360 by 84, we get 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 9028.464
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.

Step 10:
If we divide 240 by 84, we get 2 and a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 9028.4642
Deduct 168 from 240 and we're left 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.

Advancing to step 11:
If we divide 720 by 84, we get 8 and a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 9028.46428
Deduct 672 from 720 and we're left 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.

Moving on to step 12:
84 can be fit into 480 5 times, resulting in a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 9028.464285
If we subtract 420 from 480, we 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.

Going ahead to step 13:
600 divided by 84 is 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 9028.4642857
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.

Going ahead to step 14:
120 divided by 84 is 1 with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 9028.46428571
Subtract 84 from 120 to 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.

The final outcome is 9028.46428571, with a leftover of 3.6e-08.
