We're dividing 6109878 by 616 
The aim is to understand the frequency of 616 in 6109878.

Going ahead to step 1:
If we divide 6 by 616, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 616

Step 2:
When dividing 61 by 616, we get 0 with a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Take the next digit (0) from the dividend and append it to 61, then repeat: 610 / 616

Advancing to step 3:
If we divide 610 by 616, we get 0 and a remainder of 610.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 610 leaves us with 610.
Fetch the next digit (9) from the dividend, attach it to 610 and continue: 6109 / 616

Moving on to step 4:
616 can be fit into 6109 9 times, resulting in a remainder of 565.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 5544 from 6109 and we're left with 565.
Append the next digit (8) from the dividend to 565 and continue with: 5658 / 616

Advancing to step 5:
616 can be fit into 5658 9 times, resulting in a remainder of 114.
Write down 9 as next digit of the result. 
Result so far: 99.0
Deduct 5544 from 5658 and we're left with 114.
Take the next digit (7) from the dividend and append it to 114, then repeat: 1147 / 616

On to step 6:
When dividing 1147 by 616, we get 1 with a remainder of 531.
Write down 1 as next digit of the result. 
Result so far: 991.0
If we take 616 away from 1147, we end up with 531.
Grab the next digit (8) from the dividend, add it to 531, then carry on: 5318 / 616

Let's proceed to step 7:
616 can be fit into 5318 8 times, resulting in a remainder of 390.
Record the quotient 8 as the next digit in the result. 
Result so far: 9918.0
If we subtract 4928 from 5318, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 8:
The number 616 fits into 3900 6 times, leaving a remainder of 204.
Put 6 as the next digit of the answer. 
Result so far: 9918.6
Subtract 3696 from 3900 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 9:
The number 616 fits into 2040 3 times, leaving a remainder of 192.
Put 3 as the next digit of the answer. 
Result so far: 9918.63
Subtract 1848 from 2040 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 10:
If we divide 1920 by 616, we get 3 and a remainder of 72.
The next digit of our result is 3. 
Result so far: 9918.633
Subtract 1848 from 1920 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 9918.633 and a remainder of 0.0072.
