We look at the division of 285872 by 97 
The aim is to understand the frequency of 97 in 285872.

On to step 1:
The number 97 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 97

Let's proceed to step 2:
97 can be fit into 28 0 times, resulting in a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 97

On to step 3:
When dividing 285 by 97, we get 2 with a remainder of 91.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 91 after subtracting 194 from 285.
Bring next digit (8) of the dividend behind the 91 and repeat the process: 918 / 97

On to step 4:
When dividing 918 by 97, we get 9 with a remainder of 45.
The next digit of our result is 9. 
Result so far: 29.0
Subtracting 873 from 918 leaves us with 45.
Take the next digit (7) from the dividend and append it to 45, then repeat: 457 / 97

Let's proceed to step 5:
97 goes into 457 4 times with a remainder of 69.
The next digit of our result is 4. 
Result so far: 294.0
Subtracting 388 from 457 leaves us with 69.
Grab the next digit (2) from the dividend, add it to 69, then carry on: 692 / 97

Going ahead to step 6:
When dividing 692 by 97, we get 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 2947.0
Subtracting 679 from 692 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
The number 97 fits into 130 1 times, leaving a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 2947.1
If we subtract 97 from 130, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 8:
330 divided by 97 is 3 with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 2947.13
Deduct 291 from 330 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 9:
When dividing 390 by 97, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 2947.134
The remainder is 2 after subtracting 388 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
97 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2947.134
Subtracting 0 from 20 leaves us 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.

Going ahead to step 11:
97 can be fit into 200 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 2947.13402
The remainder is 6 after subtracting 194 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
When dividing 60 by 97, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 2947.13402
Deduct 0 from 60 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.

Let's proceed to step 13:
600 divided by 97 is 6 with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 2947.1340206
If we subtract 582 from 600, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
The number 97 fits into 180 1 times, leaving a remainder of 83.
The number 1 becomes the next digit in our result. 
Result so far: 2947.13402061
The remainder is 83 after subtracting 97 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

The final outcome is 2947.13402061, with a leftover of 8.3e-08.
