Let's divide 278839 by 61
The aim is to understand the frequency of 61 in 278839.

On to step 1:
61 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 61

Advancing to step 2:
27 divided by 61 is 0 with a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 27 leaves us with 27.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 61

Going ahead to step 3:
If we divide 278 by 61, we get 4 and a remainder of 34.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 244 from 278 and we're left with 34.
Append the next digit (8) from the dividend to 34 and continue with: 348 / 61

Step 4:
61 can be fit into 348 5 times, resulting in a remainder of 43.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtracting 305 from 348 leaves us with 43.
Fetch the next digit (3) from the dividend, attach it to 43 and continue: 433 / 61

Moving on to step 5:
61 can be fit into 433 7 times, resulting in a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 457.0
Subtract 427 from 433 to get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 61

Going ahead to step 6:
61 can be fit into 69 1 times, resulting in a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 4571.0
If we subtract 61 from 69, we 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.

Going ahead to step 7:
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: 4571.1
If we subtract 61 from 80, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 8:
The number 61 fits into 190 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 4571.13
If we subtract 183 from 190, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
61 goes into 70 1 times with a remainder of 9.
The next digit of our result is 1. 
Result so far: 4571.131
If we subtract 61 from 70, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
The number 61 fits into 90 1 times, leaving a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 4571.1311
If we subtract 61 from 90, we 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.

After the division, we end up with 4571.1311 and a remainder of 0.00029.
