We divide 51915992 by 245
The aim is to understand the frequency of 245 in 51915992.

Going ahead to step 1:
5 divided by 245 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 245

Moving on to step 2:
The number 245 fits into 51 0 times, leaving a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Take the next digit (9) from the dividend and append it to 51, then repeat: 519 / 245

On to step 3:
519 divided by 245 is 2 with a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 490 from 519 to get 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 245

Moving on to step 4:
The number 245 fits into 291 1 times, leaving a remainder of 46.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 245 from 291, we get 46.
Fetch the next digit (5) from the dividend, attach it to 46 and continue: 465 / 245

Moving on to step 5:
If we divide 465 by 245, we get 1 and a remainder of 220.
Write down 1 as next digit of the result. 
Result so far: 211.0
The remainder is 220 after subtracting 245 from 465.
Grab the next digit (9) from the dividend, add it to 220, then carry on: 2209 / 245

Advancing to step 6:
2209 divided by 245 is 9 with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 2119.0
Subtract 2205 from 2209 to get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 245

Going ahead to step 7:
245 can be fit into 49 0 times, resulting in a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 21190.0
Subtracting 0 from 49 leaves us with 49.
Include the next digit (2) from the dividend after 49, then repeat: 492 / 245

On to step 8:
If we divide 492 by 245, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 211902.0
Subtracting 490 from 492 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
20 divided by 245 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 211902.0
Subtract 0 from 20 to get 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 10:
When dividing 200 by 245, we get 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 211902.0
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 211902.0, and the remainder is 0.2.
