We look at the division of 919945 by 61 
The aim is to understand the frequency of 61 in 919945.

Let's proceed to step 1:
When dividing 9 by 61, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 61

On to step 2:
If we divide 91 by 61, we get 1 and a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 30 after subtracting 61 from 91.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 61

Let's proceed to step 3:
61 can be fit into 309 5 times, resulting in a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 305 from 309 to get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 61

Going ahead to step 4:
When dividing 49 by 61, we get 0 with a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 150.0
Deduct 0 from 49 and we're left with 49.
Append the next digit (4) from the dividend to 49 and continue with: 494 / 61

Let's proceed to step 5:
When dividing 494 by 61, we get 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 1508.0
The remainder is 6 after subtracting 488 from 494.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 61

Let's proceed to step 6:
61 can be fit into 65 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 15081.0
Deduct 61 from 65 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
40 divided by 61 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 15081.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
61 goes into 400 6 times with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 15081.06
Deduct 366 from 400 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
The number 61 fits into 340 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 15081.065
If we subtract 305 from 340, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 10:
If we divide 350 by 61, we get 5 and a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 15081.0655
If we take 305 away from 350, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The quotient of the division is 15081.0655, and the remainder is 0.00045.
