We look at the division of 770987 by 61 
The aim is to understand the frequency of 61 in 770987.

Let's proceed to step 1:
The number 61 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 61

Moving on to step 2:
If we divide 77 by 61, we get 1 and a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 16 after subtracting 61 from 77.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 61

Going ahead to step 3:
61 goes into 160 2 times with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 122 from 160 leaves us with 38.
Take the next digit (9) from the dividend and append it to 38, then repeat: 389 / 61

On to step 4:
If we divide 389 by 61, we get 6 and a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 126.0
If we subtract 366 from 389, we get 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 61

Step 5:
If we divide 238 by 61, we get 3 and a remainder of 55.
The next digit of our result is 3. 
Result so far: 1263.0
If we take 183 away from 238, we end up with 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 61

Going ahead to step 6:
61 goes into 557 9 times with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 12639.0
Subtract 549 from 557 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
When dividing 80 by 61, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 12639.1
Deduct 61 from 80 and we're left 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 8:
If we divide 190 by 61, we get 3 and a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 12639.13
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.

Moving on to step 9:
61 can be fit into 70 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 12639.131
Deduct 61 from 70 and we're left 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.

On 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: 12639.1311
Subtracting 61 from 90 leaves us with 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 12639.1311 with a balance of 0.00029.
