52513667 divided by 61 
The aim is to understand the frequency of 61 in 52513667.

On to step 1:
The number 61 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 61

Moving on to step 2:
When dividing 52 by 61, we get 0 with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Include the next digit (5) from the dividend after 52, then repeat: 525 / 61

Step 3:
If we divide 525 by 61, we get 8 and a remainder of 37.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 488 from 525 leaves us with 37.
Grab the next digit (1) from the dividend, add it to 37, then carry on: 371 / 61

Going ahead to step 4:
The number 61 fits into 371 6 times, leaving a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
If we take 366 away from 371, we end up with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 61

On to step 5:
If we divide 53 by 61, we get 0 and a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 860.0
If we take 0 away from 53, we end up with 53.
Fetch the next digit (6) from the dividend, attach it to 53 and continue: 536 / 61

Advancing to step 6:
536 divided by 61 is 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 8608.0
Subtract 488 from 536 to get 48.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 61

Advancing to step 7:
486 divided by 61 is 7 with a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 86087.0
Subtracting 427 from 486 leaves us with 59.
Fetch the next digit (7) from the dividend, attach it to 59 and continue: 597 / 61

Step 8:
If we divide 597 by 61, we get 9 and a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 860879.0
Deduct 549 from 597 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
The number 61 fits into 480 7 times, leaving a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 860879.7
The remainder is 53 after subtracting 427 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 10:
61 can be fit into 530 8 times, resulting in a remainder of 42.
The next digit of our result is 8. 
Result so far: 860879.78
Subtracting 488 from 530 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
The number 61 fits into 420 6 times, leaving a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 860879.786
Subtract 366 from 420 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 12:
If we divide 540 by 61, we get 8 and a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 860879.7868
Subtract 488 from 540 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 13:
If we divide 520 by 61, we get 8 and a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 860879.78688
Deduct 488 from 520 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 860879.78688, with a leftover of 3.2e-05.
