984381 divided by 85 
The aim is to understand the frequency of 85 in 984381.

On to step 1:
85 goes into 9 0 times 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.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 85

Moving on to step 2:
If we divide 98 by 85, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 85 from 98 to get 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 85

Advancing to step 3:
When dividing 134 by 85, we get 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 85 away from 134, we end up with 49.
Bring next digit (3) of the dividend behind the 49 and repeat the process: 493 / 85

Step 4:
When dividing 493 by 85, we get 5 with a remainder of 68.
The next digit of our result is 5. 
Result so far: 115.0
If we subtract 425 from 493, we get 68.
Bring next digit (8) of the dividend behind the 68 and repeat the process: 688 / 85

Moving on to step 5:
If we divide 688 by 85, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 1158.0
Subtracting 680 from 688 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 85

Let's proceed to step 6:
If we divide 81 by 85, we get 0 and a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 11580.0
Deduct 0 from 81 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 7:
85 can be fit into 810 9 times, resulting in a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 11580.9
The remainder is 45 after subtracting 765 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
85 can be fit into 450 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 11580.95
The remainder is 25 after subtracting 425 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
85 goes into 250 2 times with a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 11580.952
Deduct 170 from 250 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
If we divide 800 by 85, we get 9 and a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 11580.9529
If we subtract 765 from 800, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 11:
When dividing 350 by 85, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 11580.95294
Deduct 340 from 350 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
85 goes into 100 1 times with a remainder of 15.
The next digit of our result is 1. 
Result so far: 11580.952941
Subtract 85 from 100 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
The number 85 fits into 150 1 times, leaving a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 11580.9529411
Subtract 85 from 150 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final outcome is 11580.9529411, with a leftover of 6.5e-07.
