518386 divided by 61 
The aim is to understand the frequency of 61 in 518386.

Advancing 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
The remainder is 5 after subtracting 0 from 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 61

Step 2:
If we divide 51 by 61, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 61

Going ahead to step 3:
If we divide 518 by 61, we get 8 and a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 488 from 518 leaves us with 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 61

Step 4:
When dividing 303 by 61, we get 4 with a remainder of 59.
Write down 4 as next digit of the result. 
Result so far: 84.0
If we subtract 244 from 303, we get 59.
Grab the next digit (8) from the dividend, add it to 59, then carry on: 598 / 61

Moving on to step 5:
61 goes into 598 9 times with a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 849.0
Subtracting 549 from 598 leaves us with 49.
Include the next digit (6) from the dividend after 49, then repeat: 496 / 61

Step 6:
61 goes into 496 8 times with a remainder of 8.
The next digit of our result is 8. 
Result so far: 8498.0
Deduct 488 from 496 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
When dividing 80 by 61, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 8498.1
Subtract 61 from 80 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 8:
When dividing 190 by 61, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 8498.13
If we take 183 away from 190, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
When dividing 70 by 61, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 8498.131
Subtracting 61 from 70 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
If we divide 90 by 61, we get 1 and a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 8498.1311
If we subtract 61 from 90, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Our division results in 8498.1311 with a remaining 0.00029.
