We're dividing 898983 by 84 
The aim is to understand the frequency of 84 in 898983.

Step 1:
When dividing 8 by 84, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 84

Moving on to step 2:
When dividing 89 by 84, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 84 from 89 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 84

Let's proceed to step 3:
84 can be fit into 58 0 times, resulting in a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 58 leaves us with 58.
Include the next digit (9) from the dividend after 58, then repeat: 589 / 84

On to step 4:
84 can be fit into 589 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 107.0
The remainder is 1 after subtracting 588 from 589.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 84

On to step 5:
84 can be fit into 18 0 times, resulting in a remainder of 18.
The next digit of our result is 0. 
Result so far: 1070.0
If we subtract 0 from 18, we get 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 84

On to step 6:
When dividing 183 by 84, we get 2 with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 10702.0
The remainder is 15 after subtracting 168 from 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
84 can be fit into 150 1 times, resulting in a remainder of 66.
The number 1 becomes the next digit in our result. 
Result so far: 10702.1
The remainder is 66 after subtracting 84 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 8:
When dividing 660 by 84, we get 7 with a remainder of 72.
Write down 7 as next digit of the result. 
Result so far: 10702.17
Subtract 588 from 660 to get 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 9:
If we divide 720 by 84, we get 8 and a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 10702.178
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.

On to step 10:
The number 84 fits into 480 5 times, leaving a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 10702.1785
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.

Step 11:
The number 84 fits into 600 7 times, leaving a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 10702.17857
The remainder is 12 after subtracting 588 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
84 goes into 120 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 10702.178571
Deduct 84 from 120 and we're left 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.

Step 13:
If we divide 360 by 84, we get 4 and a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 10702.1785714
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.

Advancing to step 14:
The number 84 fits into 240 2 times, leaving a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 10702.17857142
Subtract 168 from 240 to get 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 outcome is 10702.17857142, with a leftover of 7.2e-08.
