We're dividing 85194862 by 215 
The aim is to understand the frequency of 215 in 85194862.

On to step 1:
8 divided by 215 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 215

Advancing to step 2:
When dividing 85 by 215, we get 0 with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Grab the next digit (1) from the dividend, add it to 85, then carry on: 851 / 215

Advancing to step 3:
851 divided by 215 is 3 with a remainder of 206.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 645 away from 851, we end up with 206.
Include the next digit (9) from the dividend after 206, then repeat: 2069 / 215

Step 4:
2069 divided by 215 is 9 with a remainder of 134.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Subtracting 1935 from 2069 leaves us with 134.
Take the next digit (4) from the dividend and append it to 134, then repeat: 1344 / 215

Let's proceed to step 5:
If we divide 1344 by 215, we get 6 and a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 396.0
Subtracting 1290 from 1344 leaves us with 54.
Bring next digit (8) of the dividend behind the 54 and repeat the process: 548 / 215

Going ahead to step 6:
When dividing 548 by 215, we get 2 with a remainder of 118.
Put 2 as the next digit of the answer. 
Result so far: 3962.0
Subtracting 430 from 548 leaves us with 118.
Fetch the next digit (6) from the dividend, attach it to 118 and continue: 1186 / 215

On to step 7:
1186 divided by 215 is 5 with a remainder of 111.
Record the quotient 5 as the next digit in the result. 
Result so far: 39625.0
Subtracting 1075 from 1186 leaves us with 111.
Append the next digit (2) from the dividend to 111 and continue with: 1112 / 215

Going ahead to step 8:
215 goes into 1112 5 times with a remainder of 37.
Put 5 as the next digit of the answer. 
Result so far: 396255.0
The remainder is 37 after subtracting 1075 from 1112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 9:
370 divided by 215 is 1 with a remainder of 155.
The next digit of our result is 1. 
Result so far: 396255.1
If we subtract 215 from 370, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 10:
If we divide 1550 by 215, we get 7 and a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 396255.17
The remainder is 45 after subtracting 1505 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 11:
The number 215 fits into 450 2 times, leaving a remainder of 20.
The next digit of our result is 2. 
Result so far: 396255.172
If we take 430 away from 450, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
200 divided by 215 is 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 396255.172
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 13:
215 can be fit into 2000 9 times, resulting in a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 396255.17209
Subtracting 1935 from 2000 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.

Advancing to step 14:
If we divide 650 by 215, we get 3 and a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 396255.172093
If we subtract 645 from 650, we 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.

On to step 15:
50 divided by 215 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 396255.172093
If we take 0 away from 50, we end up 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.

Going ahead to step 16:
The number 215 fits into 500 2 times, leaving a remainder of 70.
Record the quotient 2 as the next digit in the result. 
Result so far: 396255.17209302
Deduct 430 from 500 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 396255.17209302 with a remaining 7e-08.
