538629 divided by 61 
The aim is to understand the frequency of 61 in 538629.

Moving on to step 1:
If we divide 5 by 61, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 61

Step 2:
When dividing 53 by 61, we get 0 with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Fetch the next digit (8) from the dividend, attach it to 53 and continue: 538 / 61

Step 3:
The number 61 fits into 538 8 times, leaving a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 488 from 538 to get 50.
Take the next digit (6) from the dividend and append it to 50, then repeat: 506 / 61

Let's proceed to step 4:
The number 61 fits into 506 8 times, leaving a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Deduct 488 from 506 and we're left with 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 61

Moving on to step 5:
182 divided by 61 is 2 with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 882.0
The remainder is 60 after subtracting 122 from 182.
Append the next digit (9) from the dividend to 60 and continue with: 609 / 61

Let's proceed to step 6:
When dividing 609 by 61, we get 9 with a remainder of 60.
Record the quotient 9 as the next digit in the result. 
Result so far: 8829.0
Subtract 549 from 609 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
61 can be fit into 600 9 times, resulting in a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 8829.9
If we subtract 549 from 600, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 8:
If we divide 510 by 61, we get 8 and a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 8829.98
If we take 488 away from 510, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
The number 61 fits into 220 3 times, leaving a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 8829.983
Subtracting 183 from 220 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 10:
370 divided by 61 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 8829.9836
Subtract 366 from 370 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
40 divided by 61 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 8829.9836
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
The number 61 fits into 400 6 times, leaving a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 8829.983606
If we take 366 away from 400, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 13:
340 divided by 61 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 8829.9836065
The remainder is 35 after subtracting 305 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 14:
If we divide 350 by 61, we get 5 and a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 8829.98360655
Subtract 305 from 350 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 8829.98360655, with a leftover of 4.5e-08.
