423553 divided by 85 
The aim is to understand the frequency of 85 in 423553.

Going ahead to step 1:
If we divide 4 by 85, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 85

Moving on to step 2:
42 divided by 85 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 85

Going ahead to step 3:
When dividing 423 by 85, we get 4 with a remainder of 83.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 340 from 423 and we're left with 83.
Grab the next digit (5) from the dividend, add it to 83, then carry on: 835 / 85

Step 4:
835 divided by 85 is 9 with a remainder of 70.
The next digit of our result is 9. 
Result so far: 49.0
If we take 765 away from 835, we end up with 70.
Include the next digit (5) from the dividend after 70, then repeat: 705 / 85

Going ahead to step 5:
The number 85 fits into 705 8 times, leaving a remainder of 25.
Put 8 as the next digit of the answer. 
Result so far: 498.0
Subtracting 680 from 705 leaves us with 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 85

Going ahead to step 6:
253 divided by 85 is 2 with a remainder of 83.
Record the quotient 2 as the next digit in the result. 
Result so far: 4982.0
Subtracting 170 from 253 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 7:
85 can be fit into 830 9 times, resulting in a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 4982.9
Deduct 765 from 830 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 8:
When dividing 650 by 85, we get 7 with a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 4982.97
Deduct 595 from 650 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 9:
When dividing 550 by 85, we get 6 with a remainder of 40.
The next digit of our result is 6. 
Result so far: 4982.976
If we take 510 away from 550, 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.

Step 10:
85 can be fit into 400 4 times, resulting in a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 4982.9764
Subtracting 340 from 400 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.

Step 11:
600 divided by 85 is 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 4982.97647
Subtract 595 from 600 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
85 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 4982.97647
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
If we divide 500 by 85, we get 5 and a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 4982.9764705
If we take 425 away from 500, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 14:
750 divided by 85 is 8 with a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 4982.97647058
Subtract 680 from 750 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 4982.97647058 and a remainder of 7e-08.
