We look at the division of 9943473 by 85 
The aim is to understand the frequency of 85 in 9943473.

Let's proceed to step 1:
If we divide 9 by 85, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 85

Moving on to step 2:
When dividing 99 by 85, we get 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 85 from 99, we get 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 85

On to step 3:
The number 85 fits into 144 1 times, leaving a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 85 from 144, we get 59.
Grab the next digit (3) from the dividend, add it to 59, then carry on: 593 / 85

Let's proceed to step 4:
If we divide 593 by 85, we get 6 and a remainder of 83.
Use 6 as the next digit of our solution. 
Result so far: 116.0
If we subtract 510 from 593, we get 83.
Take the next digit (4) from the dividend and append it to 83, then repeat: 834 / 85

Moving on to step 5:
834 divided by 85 is 9 with a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 1169.0
Deduct 765 from 834 and we're left with 69.
Append the next digit (7) from the dividend to 69 and continue with: 697 / 85

Let's proceed to step 6:
85 goes into 697 8 times with a remainder of 17.
The next digit of our result is 8. 
Result so far: 11698.0
If we take 680 away from 697, we end up with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 85

On to step 7:
If we divide 173 by 85, we get 2 and a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 116982.0
The remainder is 3 after subtracting 170 from 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 8:
85 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 116982.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
When dividing 300 by 85, we get 3 with a remainder of 45.
The next digit of our result is 3. 
Result so far: 116982.03
If we take 255 away from 300, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 10:
450 divided by 85 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 116982.035
If we take 425 away from 450, we end up with 25.
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 11:
The number 85 fits into 250 2 times, leaving a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 116982.0352
If we subtract 170 from 250, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
85 can be fit into 800 9 times, resulting in a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 116982.03529
The remainder is 35 after subtracting 765 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 13:
350 divided by 85 is 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 116982.035294
Subtracting 340 from 350 leaves us 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.

Going ahead to step 14:
100 divided by 85 is 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 116982.0352941
If we take 85 away from 100, we end up 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.

Let's proceed to step 15:
When dividing 150 by 85, we get 1 with a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 116982.03529411
If we subtract 85 from 150, we 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.

Our division results in 116982.03529411 with a remaining 6.5e-08.
