We look at the division of 84475589 by 215 
The aim is to understand the frequency of 215 in 84475589.

Advancing to step 1:
If we divide 8 by 215, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 215

Step 2:
215 goes into 84 0 times with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Fetch the next digit (4) from the dividend, attach it to 84 and continue: 844 / 215

On to step 3:
The number 215 fits into 844 3 times, leaving a remainder of 199.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 199 after subtracting 645 from 844.
Bring next digit (7) of the dividend behind the 199 and repeat the process: 1997 / 215

Let's proceed to step 4:
The number 215 fits into 1997 9 times, leaving a remainder of 62.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we take 1935 away from 1997, we end up with 62.
Include the next digit (5) from the dividend after 62, then repeat: 625 / 215

Going ahead to step 5:
When dividing 625 by 215, we get 2 with a remainder of 195.
The next digit of our result is 2. 
Result so far: 392.0
Subtract 430 from 625 to get 195.
Grab the next digit (5) from the dividend, add it to 195, then carry on: 1955 / 215

Step 6:
If we divide 1955 by 215, we get 9 and a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 3929.0
The remainder is 20 after subtracting 1935 from 1955.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 215

Advancing to step 7:
215 can be fit into 208 0 times, resulting in a remainder of 208.
Use 0 as the next digit of our solution. 
Result so far: 39290.0
Subtract 0 from 208 to get 208.
Fetch the next digit (9) from the dividend, attach it to 208 and continue: 2089 / 215

Advancing to step 8:
When dividing 2089 by 215, we get 9 with a remainder of 154.
The number 9 becomes the next digit in our result. 
Result so far: 392909.0
Deduct 1935 from 2089 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 9:
When dividing 1540 by 215, we get 7 with a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 392909.7
If we subtract 1505 from 1540, 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.

Step 10:
215 can be fit into 350 1 times, resulting in a remainder of 135.
Put 1 as the next digit of the answer. 
Result so far: 392909.71
Deduct 215 from 350 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 11:
1350 divided by 215 is 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 392909.716
Subtract 1290 from 1350 to get 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:
215 can be fit into 600 2 times, resulting in a remainder of 170.
Write down 2 as next digit of the result. 
Result so far: 392909.7162
Subtracting 430 from 600 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 13:
When dividing 1700 by 215, we get 7 with a remainder of 195.
Use 7 as the next digit of our solution. 
Result so far: 392909.71627
The remainder is 195 after subtracting 1505 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 14:
215 can be fit into 1950 9 times, resulting in a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 392909.716279
Subtracting 1935 from 1950 leaves us 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.

Going ahead to step 15:
If we divide 150 by 215, we get 0 and a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 392909.716279
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 16:
When dividing 1500 by 215, we get 6 with a remainder of 210.
Put 6 as the next digit of the answer. 
Result so far: 392909.71627906
Deduct 1290 from 1500 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

In conclusion, the division gives 392909.71627906 with a balance of 2.1e-07.
