We look at the division of 55080421 by 986 
The aim is to understand the frequency of 986 in 55080421.

Let's proceed to step 1:
986 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 986

Moving on to step 2:
If we divide 55 by 986, we get 0 and a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Append the next digit (0) from the dividend to 55 and continue with: 550 / 986

On to step 3:
986 can be fit into 550 0 times, resulting in a remainder of 550.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 550 and we're left with 550.
Include the next digit (8) from the dividend after 550, then repeat: 5508 / 986

Moving on to step 4:
5508 divided by 986 is 5 with a remainder of 578.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 578 after subtracting 4930 from 5508.
Bring next digit (0) of the dividend behind the 578 and repeat the process: 5780 / 986

On to step 5:
When dividing 5780 by 986, we get 5 with a remainder of 850.
The next digit of our result is 5. 
Result so far: 55.0
Deduct 4930 from 5780 and we're left with 850.
Include the next digit (4) from the dividend after 850, then repeat: 8504 / 986

Advancing to step 6:
986 can be fit into 8504 8 times, resulting in a remainder of 616.
Put 8 as the next digit of the answer. 
Result so far: 558.0
Deduct 7888 from 8504 and we're left with 616.
Include the next digit (2) from the dividend after 616, then repeat: 6162 / 986

Let's proceed to step 7:
The number 986 fits into 6162 6 times, leaving a remainder of 246.
The next digit of our result is 6. 
Result so far: 5586.0
If we subtract 5916 from 6162, we get 246.
Append the next digit (1) from the dividend to 246 and continue with: 2461 / 986

Let's proceed to step 8:
986 goes into 2461 2 times with a remainder of 489.
The number 2 becomes the next digit in our result. 
Result so far: 55862.0
If we take 1972 away from 2461, we end up with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Advancing to step 9:
The number 986 fits into 4890 4 times, leaving a remainder of 946.
Write down 4 as next digit of the result. 
Result so far: 55862.4
Subtracting 3944 from 4890 leaves us with 946.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9460, and continue the process.

Let's proceed to step 10:
986 goes into 9460 9 times with a remainder of 586.
Put 9 as the next digit of the answer. 
Result so far: 55862.49
If we subtract 8874 from 9460, we get 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Advancing to step 11:
986 goes into 5860 5 times with a remainder of 930.
The next digit of our result is 5. 
Result so far: 55862.495
The remainder is 930 after subtracting 4930 from 5860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9300, and continue the process.

Step 12:
When dividing 9300 by 986, we get 9 with a remainder of 426.
Put 9 as the next digit of the answer. 
Result so far: 55862.4959
The remainder is 426 after subtracting 8874 from 9300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Advancing to step 13:
The number 986 fits into 4260 4 times, leaving a remainder of 316.
Record the quotient 4 as the next digit in the result. 
Result so far: 55862.49594
Subtracting 3944 from 4260 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Advancing to step 14:
If we divide 3160 by 986, we get 3 and a remainder of 202.
Record the quotient 3 as the next digit in the result. 
Result so far: 55862.495943
The remainder is 202 after subtracting 2958 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 15:
986 can be fit into 2020 2 times, resulting in a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 55862.4959432
Deduct 1972 from 2020 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 16:
986 goes into 480 0 times with a remainder of 480.
The next digit of our result is 0. 
Result so far: 55862.4959432
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

After the division, we end up with 55862.4959432 and a remainder of 4.8e-07.
