We divide 86189891 by 335
The aim is to understand the frequency of 335 in 86189891.

On to step 1:
8 divided by 335 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 335

Step 2:
When dividing 86 by 335, we get 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Take the next digit (1) from the dividend and append it to 86, then repeat: 861 / 335

Going ahead to step 3:
861 divided by 335 is 2 with a remainder of 191.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 670 from 861 to get 191.
Include the next digit (8) from the dividend after 191, then repeat: 1918 / 335

On to step 4:
335 goes into 1918 5 times with a remainder of 243.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we subtract 1675 from 1918, we get 243.
Bring next digit (9) of the dividend behind the 243 and repeat the process: 2439 / 335

On to step 5:
The number 335 fits into 2439 7 times, leaving a remainder of 94.
Write down 7 as next digit of the result. 
Result so far: 257.0
Subtracting 2345 from 2439 leaves us with 94.
Fetch the next digit (8) from the dividend, attach it to 94 and continue: 948 / 335

On to step 6:
948 divided by 335 is 2 with a remainder of 278.
Use 2 as the next digit of our solution. 
Result so far: 2572.0
Subtracting 670 from 948 leaves us with 278.
Include the next digit (9) from the dividend after 278, then repeat: 2789 / 335

On to step 7:
The number 335 fits into 2789 8 times, leaving a remainder of 109.
Write down 8 as next digit of the result. 
Result so far: 25728.0
Deduct 2680 from 2789 and we're left with 109.
Take the next digit (1) from the dividend and append it to 109, then repeat: 1091 / 335

Step 8:
The number 335 fits into 1091 3 times, leaving a remainder of 86.
Use 3 as the next digit of our solution. 
Result so far: 257283.0
Deduct 1005 from 1091 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 9:
860 divided by 335 is 2 with a remainder of 190.
Write down 2 as next digit of the result. 
Result so far: 257283.2
If we subtract 670 from 860, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 10:
335 can be fit into 1900 5 times, resulting in a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 257283.25
Subtracting 1675 from 1900 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 11:
The number 335 fits into 2250 6 times, leaving a remainder of 240.
Record the quotient 6 as the next digit in the result. 
Result so far: 257283.256
Subtract 2010 from 2250 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 12:
The number 335 fits into 2400 7 times, leaving a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 257283.2567
Deduct 2345 from 2400 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.

On to step 13:
550 divided by 335 is 1 with a remainder of 215.
The next digit of our result is 1. 
Result so far: 257283.25671
Deduct 335 from 550 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 14:
When dividing 2150 by 335, we get 6 with a remainder of 140.
Record the quotient 6 as the next digit in the result. 
Result so far: 257283.256716
If we take 2010 away from 2150, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 15:
335 can be fit into 1400 4 times, resulting in a remainder of 60.
The next digit of our result is 4. 
Result so far: 257283.2567164
Deduct 1340 from 1400 and we're left 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.

On to step 16:
335 goes into 600 1 times with a remainder of 265.
Write down 1 as next digit of the result. 
Result so far: 257283.25671641
The remainder is 265 after subtracting 335 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

After the division, we end up with 257283.25671641 and a remainder of 2.65e-07.
