18723546 ÷ 245 
The aim is to understand the frequency of 245 in 18723546.

Going ahead to step 1:
1 divided by 245 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 245

Advancing to step 2:
18 divided by 245 is 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 245

On to step 3:
The number 245 fits into 187 0 times, leaving a remainder of 187.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 187 and we're left with 187.
Bring next digit (2) of the dividend behind the 187 and repeat the process: 1872 / 245

Advancing to step 4:
245 can be fit into 1872 7 times, resulting in a remainder of 157.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 157 after subtracting 1715 from 1872.
Fetch the next digit (3) from the dividend, attach it to 157 and continue: 1573 / 245

Advancing to step 5:
The number 245 fits into 1573 6 times, leaving a remainder of 103.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
The remainder is 103 after subtracting 1470 from 1573.
Take the next digit (5) from the dividend and append it to 103, then repeat: 1035 / 245

Step 6:
245 can be fit into 1035 4 times, resulting in a remainder of 55.
Record the quotient 4 as the next digit in the result. 
Result so far: 764.0
If we take 980 away from 1035, we end up with 55.
Fetch the next digit (4) from the dividend, attach it to 55 and continue: 554 / 245

Going ahead to step 7:
245 can be fit into 554 2 times, resulting in a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 7642.0
If we subtract 490 from 554, we get 64.
Append the next digit (6) from the dividend to 64 and continue with: 646 / 245

Advancing to step 8:
The number 245 fits into 646 2 times, leaving a remainder of 156.
Write down 2 as next digit of the result. 
Result so far: 76422.0
If we take 490 away from 646, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 9:
1560 divided by 245 is 6 with a remainder of 90.
Write down 6 as next digit of the result. 
Result so far: 76422.6
If we subtract 1470 from 1560, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 10:
If we divide 900 by 245, we get 3 and a remainder of 165.
Put 3 as the next digit of the answer. 
Result so far: 76422.63
Subtract 735 from 900 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 11:
1650 divided by 245 is 6 with a remainder of 180.
The next digit of our result is 6. 
Result so far: 76422.636
If we subtract 1470 from 1650, we 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.

Moving on to step 12:
When dividing 1800 by 245, we get 7 with a remainder of 85.
Record the quotient 7 as the next digit in the result. 
Result so far: 76422.6367
Deduct 1715 from 1800 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 13:
If we divide 850 by 245, we get 3 and a remainder of 115.
The next digit of our result is 3. 
Result so far: 76422.63673
If we take 735 away from 850, we end up 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.

On to step 14:
245 goes into 1150 4 times with a remainder of 170.
Put 4 as the next digit of the answer. 
Result so far: 76422.636734
If we take 980 away from 1150, we end up 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.

Let's proceed to step 15:
If we divide 1700 by 245, we get 6 and a remainder of 230.
Use 6 as the next digit of our solution. 
Result so far: 76422.6367346
Subtract 1470 from 1700 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 16:
When dividing 2300 by 245, we get 9 with a remainder of 95.
The number 9 becomes the next digit in our result. 
Result so far: 76422.63673469
If we subtract 2205 from 2300, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

The final result is 76422.63673469 with a remainder of 9.5e-08.
