851897 ÷ 85 
The aim is to understand the frequency of 85 in 851897.

Let's proceed to step 1:
If we divide 8 by 85, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 85

Let's proceed to step 2:
The number 85 fits into 85 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 85 from 85 leaves us with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 85

Advancing to step 3:
1 divided by 85 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 1 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 85

On to step 4:
When dividing 18 by 85, we get 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 100.0
If we take 0 away from 18, we end up with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 85

On to step 5:
When dividing 189 by 85, we get 2 with a remainder of 19.
The next digit of our result is 2. 
Result so far: 1002.0
The remainder is 19 after subtracting 170 from 189.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 85

On to step 6:
197 divided by 85 is 2 with a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 10022.0
Deduct 170 from 197 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
85 can be fit into 270 3 times, resulting in a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 10022.3
Deduct 255 from 270 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.

Moving on to step 8:
The number 85 fits into 150 1 times, leaving a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 10022.31
Subtracting 85 from 150 leaves us 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 9:
85 goes into 650 7 times with a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 10022.317
Subtract 595 from 650 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 10:
The number 85 fits into 550 6 times, leaving a remainder of 40.
The next digit of our result is 6. 
Result so far: 10022.3176
Deduct 510 from 550 and we're left 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.

Let's proceed to step 11:
If we divide 400 by 85, we get 4 and a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 10022.31764
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.

Advancing to step 12:
The number 85 fits into 600 7 times, leaving a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 10022.317647
Subtracting 595 from 600 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
85 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 10022.317647
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 14:
When dividing 500 by 85, we get 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 10022.31764705
The remainder is 75 after subtracting 425 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Our division results in 10022.31764705 with a remaining 7.5e-08.
