We're dividing 898564 by 84 
The aim is to understand the frequency of 84 in 898564.

Going ahead to step 1:
8 divided by 84 is 0 with a remainder of 8.
The next digit of our result is 0. 
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

Going ahead to step 2:
If we divide 89 by 84, we get 1 and a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 84 from 89, we get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 84

Going ahead to step 3:
When dividing 58 by 84, we get 0 with a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 58, we end up with 58.
Include the next digit (5) from the dividend after 58, then repeat: 585 / 84

Moving on to step 4:
585 divided by 84 is 6 with a remainder of 81.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
If we subtract 504 from 585, we get 81.
Fetch the next digit (6) from the dividend, attach it to 81 and continue: 816 / 84

Step 5:
84 can be fit into 816 9 times, resulting in a remainder of 60.
The next digit of our result is 9. 
Result so far: 1069.0
Subtract 756 from 816 to get 60.
Include the next digit (4) from the dividend after 60, then repeat: 604 / 84

Advancing to step 6:
If we divide 604 by 84, we get 7 and a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 10697.0
Subtracting 588 from 604 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
84 goes into 160 1 times with a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 10697.1
If we subtract 84 from 160, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 8:
If we divide 760 by 84, we get 9 and a remainder of 4.
The next digit of our result is 9. 
Result so far: 10697.19
Subtract 756 from 760 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
The number 84 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 10697.19
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
The number 84 fits into 400 4 times, leaving a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 10697.1904
Subtracting 336 from 400 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 11:
The number 84 fits into 640 7 times, leaving a remainder of 52.
The next digit of our result is 7. 
Result so far: 10697.19047
Subtracting 588 from 640 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 12:
If we divide 520 by 84, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 10697.190476
If we subtract 504 from 520, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
When dividing 160 by 84, we get 1 with a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 10697.1904761
Deduct 84 from 160 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 14:
84 goes into 760 9 times with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 10697.19047619
If we take 756 away from 760, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 10697.19047619, with a leftover of 4e-09.
