Let's divide 879843 by 61
The aim is to understand the frequency of 61 in 879843.

Let's proceed to step 1:
61 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 61

Step 2:
87 divided by 61 is 1 with a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 61 from 87 leaves us with 26.
Fetch the next digit (9) from the dividend, attach it to 26 and continue: 269 / 61

Going ahead to step 3:
269 divided by 61 is 4 with a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 244 from 269 leaves us with 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 61

Step 4:
61 can be fit into 258 4 times, resulting in a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 144.0
Deduct 244 from 258 and we're left with 14.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 61

Step 5:
When dividing 144 by 61, we get 2 with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 1442.0
If we subtract 122 from 144, we get 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 61

Moving on to step 6:
61 goes into 223 3 times with a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 14423.0
Subtracting 183 from 223 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
61 can be fit into 400 6 times, resulting in a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 14423.6
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 8:
When dividing 340 by 61, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 14423.65
The remainder is 35 after subtracting 305 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
The number 61 fits into 350 5 times, leaving a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 14423.655
Deduct 305 from 350 and we're left 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 14423.655, and the remainder is 0.0045.
