We're dividing 36381949 by 85 
The aim is to understand the frequency of 85 in 36381949.

On to step 1:
If we divide 3 by 85, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 85

Step 2:
36 divided by 85 is 0 with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 36 after subtracting 0 from 36.
Grab the next digit (3) from the dividend, add it to 36, then carry on: 363 / 85

Advancing to step 3:
The number 85 fits into 363 4 times, leaving a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 23 after subtracting 340 from 363.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 85

Step 4:
If we divide 238 by 85, we get 2 and a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we take 170 away from 238, we end up with 68.
Include the next digit (1) from the dividend after 68, then repeat: 681 / 85

Let's proceed to step 5:
681 divided by 85 is 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 428.0
If we take 680 away from 681, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 85

Step 6:
85 can be fit into 19 0 times, resulting in a remainder of 19.
The next digit of our result is 0. 
Result so far: 4280.0
Subtracting 0 from 19 leaves us with 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 85

Step 7:
If we divide 194 by 85, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 42802.0
Subtract 170 from 194 to get 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 85

On to step 8:
85 goes into 249 2 times with a remainder of 79.
Record the quotient 2 as the next digit in the result. 
Result so far: 428022.0
If we take 170 away from 249, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 9:
The number 85 fits into 790 9 times, leaving a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 428022.9
Subtracting 765 from 790 leaves us 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.

Going ahead to step 10:
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: 428022.92
The remainder is 80 after subtracting 170 from 250.
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 11:
When dividing 800 by 85, we get 9 with a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 428022.929
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.

On to step 12:
85 can be fit into 350 4 times, resulting in a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 428022.9294
Subtract 340 from 350 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
85 goes into 100 1 times with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 428022.92941
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.

Let's proceed to step 14:
The number 85 fits into 150 1 times, leaving a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 428022.929411
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.

After the division, we end up with 428022.929411 and a remainder of 6.5e-06.
