991803 ÷ 84 
The aim is to understand the frequency of 84 in 991803.

Advancing to step 1:
9 divided by 84 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 84

Let's proceed to step 2:
84 can be fit into 99 1 times, resulting in a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 84 from 99 and we're left with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 84

Let's proceed to step 3:
When dividing 151 by 84, we get 1 with a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 84 from 151, we get 67.
Include the next digit (8) from the dividend after 67, then repeat: 678 / 84

Going ahead to step 4:
The number 84 fits into 678 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 118.0
The remainder is 6 after subtracting 672 from 678.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 84

Let's proceed to step 5:
60 divided by 84 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 1180.0
Subtract 0 from 60 to get 60.
Take the next digit (3) from the dividend and append it to 60, then repeat: 603 / 84

Step 6:
When dividing 603 by 84, we get 7 with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 11807.0
Deduct 588 from 603 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
84 can be fit into 150 1 times, resulting in a remainder of 66.
Record the quotient 1 as the next digit in the result. 
Result so far: 11807.1
Subtracting 84 from 150 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 8:
When dividing 660 by 84, we get 7 with a remainder of 72.
Put 7 as the next digit of the answer. 
Result so far: 11807.17
Deduct 588 from 660 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.

Step 9:
720 divided by 84 is 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 11807.178
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.

Let's proceed to step 10:
The number 84 fits into 480 5 times, leaving a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 11807.1785
Subtracting 420 from 480 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
When dividing 600 by 84, we get 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 11807.17857
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.

Advancing to step 12:
When dividing 120 by 84, we get 1 with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 11807.178571
Subtracting 84 from 120 leaves us 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.

Let's proceed to step 13:
When dividing 360 by 84, we get 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 11807.1785714
If we take 336 away from 360, we end up with 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 14:
The number 84 fits into 240 2 times, leaving a remainder of 72.
The next digit of our result is 2. 
Result so far: 11807.17857142
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.

The final result is 11807.17857142 with a remainder of 7.2e-08.
