We divide 20628000 by 245
The aim is to understand the frequency of 245 in 20628000.

Going ahead to step 1:
2 divided by 245 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 245

Going ahead to step 2:
If we divide 20 by 245, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 245

Advancing to step 3:
If we divide 206 by 245, we get 0 and a remainder of 206.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 206 to get 206.
Append the next digit (2) from the dividend to 206 and continue with: 2062 / 245

Let's proceed to step 4:
2062 divided by 245 is 8 with a remainder of 102.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 1960 from 2062 to get 102.
Take the next digit (8) from the dividend and append it to 102, then repeat: 1028 / 245

On to step 5:
The number 245 fits into 1028 4 times, leaving a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
If we subtract 980 from 1028, we get 48.
Append the next digit (0) from the dividend to 48 and continue with: 480 / 245

Going ahead to step 6:
245 goes into 480 1 times with a remainder of 235.
The next digit of our result is 1. 
Result so far: 841.0
If we take 245 away from 480, we end up with 235.
Take the next digit (0) from the dividend and append it to 235, then repeat: 2350 / 245

Moving on to step 7:
245 can be fit into 2350 9 times, resulting in a remainder of 145.
Put 9 as the next digit of the answer. 
Result so far: 8419.0
Subtract 2205 from 2350 to get 145.
Take the next digit (0) from the dividend and append it to 145, then repeat: 1450 / 245

Going ahead to step 8:
245 can be fit into 1450 5 times, resulting in a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 84195.0
Subtracting 1225 from 1450 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 9:
245 goes into 2250 9 times with a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 84195.9
The remainder is 45 after subtracting 2205 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
245 can be fit into 450 1 times, resulting in a remainder of 205.
The number 1 becomes the next digit in our result. 
Result so far: 84195.91
Subtract 245 from 450 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 11:
245 can be fit into 2050 8 times, resulting in a remainder of 90.
The number 8 becomes the next digit in our result. 
Result so far: 84195.918
Deduct 1960 from 2050 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 12:
900 divided by 245 is 3 with a remainder of 165.
Write down 3 as next digit of the result. 
Result so far: 84195.9183
The remainder is 165 after subtracting 735 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 13:
245 goes into 1650 6 times with a remainder of 180.
Use 6 as the next digit of our solution. 
Result so far: 84195.91836
Subtract 1470 from 1650 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 14:
245 can be fit into 1800 7 times, resulting in a remainder of 85.
Use 7 as the next digit of our solution. 
Result so far: 84195.918367
The remainder is 85 after subtracting 1715 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 15:
When dividing 850 by 245, we get 3 with a remainder of 115.
Put 3 as the next digit of the answer. 
Result so far: 84195.9183673
Subtracting 735 from 850 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 16:
245 can be fit into 1150 4 times, resulting in a remainder of 170.
Record the quotient 4 as the next digit in the result. 
Result so far: 84195.91836734
The remainder is 170 after subtracting 980 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final result is 84195.91836734 with a remainder of 1.7e-07.
