We look at the division of 746043 by 84 
The aim is to understand the frequency of 84 in 746043.

Let's proceed to step 1:
If we divide 7 by 84, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 84

Advancing to step 2:
The number 84 fits into 74 0 times, leaving a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Take the next digit (6) from the dividend and append it to 74, then repeat: 746 / 84

Advancing to step 3:
84 can be fit into 746 8 times, resulting in a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 672 from 746 to get 74.
Append the next digit (0) from the dividend to 74 and continue with: 740 / 84

Let's proceed to step 4:
When dividing 740 by 84, we get 8 with a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 88.0
The remainder is 68 after subtracting 672 from 740.
Take the next digit (4) from the dividend and append it to 68, then repeat: 684 / 84

Advancing to step 5:
84 goes into 684 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 888.0
Deduct 672 from 684 and we're left with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 84

On to step 6:
The number 84 fits into 123 1 times, leaving a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 8881.0
If we subtract 84 from 123, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
84 can be fit into 390 4 times, resulting in a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 8881.4
Subtracting 336 from 390 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 8:
The number 84 fits into 540 6 times, leaving a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 8881.46
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.

Going ahead to step 9:
84 can be fit into 360 4 times, resulting in a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 8881.464
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.

Advancing to 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: 8881.4642
If we take 168 away from 240, we end up 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.

Let's proceed to step 11:
84 can be fit into 720 8 times, resulting in a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 8881.46428
The remainder is 48 after subtracting 672 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 12:
480 divided by 84 is 5 with a remainder of 60.
The next digit of our result is 5. 
Result so far: 8881.464285
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
If we divide 600 by 84, we get 7 and a remainder of 12.
The next digit of our result is 7. 
Result so far: 8881.4642857
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.

Let's proceed to step 14:
120 divided by 84 is 1 with a remainder of 36.
The next digit of our result is 1. 
Result so far: 8881.46428571
The remainder is 36 after subtracting 84 from 120.
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 8881.46428571, with a leftover of 3.6e-08.
