We look at the division of 686248 by 61 
The aim is to understand the frequency of 61 in 686248.

Let's proceed to step 1:
If we divide 6 by 61, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 61

Advancing to step 2:
68 divided by 61 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 61 away from 68, we end up with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 61

Moving on to step 3:
76 divided by 61 is 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 61 from 76 and we're left with 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 61

Step 4:
When dividing 152 by 61, we get 2 with a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
Deduct 122 from 152 and we're left with 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 61

Let's proceed to step 5:
If we divide 304 by 61, we get 4 and a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 1124.0
The remainder is 60 after subtracting 244 from 304.
Append the next digit (8) from the dividend to 60 and continue with: 608 / 61

Let's proceed to step 6:
61 goes into 608 9 times with a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 11249.0
If we take 549 away from 608, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 7:
590 divided by 61 is 9 with a remainder of 41.
The next digit of our result is 9. 
Result so far: 11249.9
If we subtract 549 from 590, we 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.

Moving on to step 8:
410 divided by 61 is 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 11249.96
If we take 366 away from 410, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
61 goes into 440 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 11249.967
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.

Step 10:
61 can be fit into 130 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 11249.9672
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 11:
61 can be fit into 80 1 times, resulting in a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 11249.96721
Subtracting 61 from 80 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 12:
The number 61 fits into 190 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 11249.967213
The remainder is 7 after subtracting 183 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 13:
70 divided by 61 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 11249.9672131
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.

Let's proceed to step 14:
61 goes into 90 1 times with a remainder of 29.
The next digit of our result is 1. 
Result so far: 11249.96721311
Subtract 61 from 90 to 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.

In conclusion, the division gives 11249.96721311 with a balance of 2.9e-08.
