We're dividing 312831 by 61 
The aim is to understand the frequency of 61 in 312831.

Let's proceed to step 1:
The number 61 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 61

Let's proceed to step 2:
The number 61 fits into 31 0 times, leaving a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 61

Step 3:
312 divided by 61 is 5 with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 305 from 312 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 61

Step 4:
The number 61 fits into 78 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we take 61 away from 78, we end up with 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 61

Advancing to step 5:
If we divide 173 by 61, we get 2 and a remainder of 51.
The number 2 becomes the next digit in our result. 
Result so far: 512.0
Subtract 122 from 173 to get 51.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 61

Let's proceed to step 6:
If we divide 511 by 61, we get 8 and a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 5128.0
The remainder is 23 after subtracting 488 from 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
If we divide 230 by 61, we get 3 and a remainder of 47.
The next digit of our result is 3. 
Result so far: 5128.3
Subtracting 183 from 230 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 8:
61 goes into 470 7 times with a remainder of 43.
The next digit of our result is 7. 
Result so far: 5128.37
Deduct 427 from 470 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
When dividing 430 by 61, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 5128.377
The remainder is 3 after subtracting 427 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The quotient of the division is 5128.377, and the remainder is 0.0003.
