We look at the division of 252297 by 61 
The aim is to understand the frequency of 61 in 252297.

On to step 1:
The number 61 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 61

Step 2:
61 goes into 25 0 times with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Fetch the next digit (2) from the dividend, attach it to 25 and continue: 252 / 61

On to step 3:
61 goes into 252 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 244 from 252 leaves us with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 61

Advancing to step 4:
If we divide 82 by 61, we get 1 and a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 41.0
If we subtract 61 from 82, we get 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 61

On to step 5:
219 divided by 61 is 3 with a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 413.0
Subtract 183 from 219 to get 36.
Include the next digit (7) from the dividend after 36, then repeat: 367 / 61

Going ahead to step 6:
367 divided by 61 is 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 4136.0
If we take 366 away from 367, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
If we divide 10 by 61, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 4136.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
If we divide 100 by 61, we get 1 and a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 4136.01
Deduct 61 from 100 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.

Step 9:
If we divide 390 by 61, we get 6 and a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 4136.016
Subtracting 366 from 390 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
If we divide 240 by 61, we get 3 and a remainder of 57.
The next digit of our result is 3. 
Result so far: 4136.0163
If we take 183 away from 240, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 11:
61 can be fit into 570 9 times, resulting in a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 4136.01639
The remainder is 21 after subtracting 549 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 12:
210 divided by 61 is 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 4136.016393
If we take 183 away from 210, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 13:
61 goes into 270 4 times with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 4136.0163934
If we subtract 244 from 270, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
61 goes into 260 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 4136.01639344
If we take 244 away from 260, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 4136.01639344 with a balance of 1.6e-08.
