We look at the division of 54474928 by 245 
The aim is to understand the frequency of 245 in 54474928.

Step 1:
If we divide 5 by 245, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 245

Advancing to step 2:
When dividing 54 by 245, we get 0 with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Include the next digit (4) from the dividend after 54, then repeat: 544 / 245

On to step 3:
If we divide 544 by 245, we get 2 and a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 490 from 544, we get 54.
Grab the next digit (7) from the dividend, add it to 54, then carry on: 547 / 245

Moving on to step 4:
The number 245 fits into 547 2 times, leaving a remainder of 57.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Deduct 490 from 547 and we're left with 57.
Include the next digit (4) from the dividend after 57, then repeat: 574 / 245

Advancing to step 5:
When dividing 574 by 245, we get 2 with a remainder of 84.
Put 2 as the next digit of the answer. 
Result so far: 222.0
If we take 490 away from 574, we end up with 84.
Fetch the next digit (9) from the dividend, attach it to 84 and continue: 849 / 245

Step 6:
If we divide 849 by 245, we get 3 and a remainder of 114.
Put 3 as the next digit of the answer. 
Result so far: 2223.0
Subtract 735 from 849 to get 114.
Include the next digit (2) from the dividend after 114, then repeat: 1142 / 245

Step 7:
The number 245 fits into 1142 4 times, leaving a remainder of 162.
Write down 4 as next digit of the result. 
Result so far: 22234.0
If we take 980 away from 1142, we end up with 162.
Fetch the next digit (8) from the dividend, attach it to 162 and continue: 1628 / 245

Going ahead to step 8:
1628 divided by 245 is 6 with a remainder of 158.
Record the quotient 6 as the next digit in the result. 
Result so far: 222346.0
Deduct 1470 from 1628 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 9:
If we divide 1580 by 245, we get 6 and a remainder of 110.
Write down 6 as next digit of the result. 
Result so far: 222346.6
Subtracting 1470 from 1580 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
When dividing 1100 by 245, we get 4 with a remainder of 120.
Use 4 as the next digit of our solution. 
Result so far: 222346.64
Deduct 980 from 1100 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
If we divide 1200 by 245, we get 4 and a remainder of 220.
Use 4 as the next digit of our solution. 
Result so far: 222346.644
If we subtract 980 from 1200, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final outcome is 222346.644, with a leftover of 0.022.
