Let's divide 511551 by 61
The aim is to understand the frequency of 61 in 511551.

Going ahead 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.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 61

On to step 2:
If we divide 51 by 61, we get 0 and a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Fetch the next digit (1) from the dividend, attach it to 51 and continue: 511 / 61

Step 3:
511 divided by 61 is 8 with a remainder of 23.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 488 from 511 leaves us with 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 61

Moving on to step 4:
The number 61 fits into 235 3 times, leaving a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
If we subtract 183 from 235, we get 52.
Include the next digit (5) from the dividend after 52, then repeat: 525 / 61

Moving on to step 5:
When dividing 525 by 61, we get 8 with a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 838.0
Deduct 488 from 525 and we're left with 37.
Bring next digit (1) of the dividend behind the 37 and repeat the process: 371 / 61

Let's proceed to step 6:
61 can be fit into 371 6 times, resulting in a remainder of 5.
The next digit of our result is 6. 
Result so far: 8386.0
Deduct 366 from 371 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
When dividing 50 by 61, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 8386.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
500 divided by 61 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 8386.08
Subtract 488 from 500 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
If we divide 120 by 61, we get 1 and a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 8386.081
The remainder is 59 after subtracting 61 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 10:
61 goes into 590 9 times with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 8386.0819
Subtract 549 from 590 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 11:
If we divide 410 by 61, we get 6 and a remainder of 44.
The next digit of our result is 6. 
Result so far: 8386.08196
Subtract 366 from 410 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 12:
The number 61 fits into 440 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 8386.081967
The remainder is 13 after subtracting 427 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 13:
61 goes into 130 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 8386.0819672
The remainder is 8 after subtracting 122 from 130.
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 14:
61 goes into 80 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 8386.08196721
The remainder is 19 after subtracting 61 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Our division results in 8386.08196721 with a remaining 1.9e-08.
