We're dividing 55159005 by 808 
The aim is to understand the frequency of 808 in 55159005.

On to step 1:
The number 808 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 808

On to step 2:
808 can be fit into 55 0 times, resulting in a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Include the next digit (1) from the dividend after 55, then repeat: 551 / 808

Moving on to step 3:
When dividing 551 by 808, we get 0 with a remainder of 551.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 551, we end up with 551.
Include the next digit (5) from the dividend after 551, then repeat: 5515 / 808

Advancing to step 4:
808 can be fit into 5515 6 times, resulting in a remainder of 667.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 4848 from 5515 and we're left with 667.
Take the next digit (9) from the dividend and append it to 667, then repeat: 6679 / 808

On to step 5:
The number 808 fits into 6679 8 times, leaving a remainder of 215.
Put 8 as the next digit of the answer. 
Result so far: 68.0
If we subtract 6464 from 6679, we get 215.
Append the next digit (0) from the dividend to 215 and continue with: 2150 / 808

Advancing to step 6:
808 goes into 2150 2 times with a remainder of 534.
Record the quotient 2 as the next digit in the result. 
Result so far: 682.0
Deduct 1616 from 2150 and we're left with 534.
Append the next digit (0) from the dividend to 534 and continue with: 5340 / 808

Let's proceed to step 7:
808 can be fit into 5340 6 times, resulting in a remainder of 492.
The number 6 becomes the next digit in our result. 
Result so far: 6826.0
Subtract 4848 from 5340 to get 492.
Grab the next digit (5) from the dividend, add it to 492, then carry on: 4925 / 808

Moving on to step 8:
If we divide 4925 by 808, we get 6 and a remainder of 77.
Use 6 as the next digit of our solution. 
Result so far: 68266.0
Deduct 4848 from 4925 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 9:
770 divided by 808 is 0 with a remainder of 770.
Put 0 as the next digit of the answer. 
Result so far: 68266.0
The remainder is 770 after subtracting 0 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Moving on to step 10:
If we divide 7700 by 808, we get 9 and a remainder of 428.
Put 9 as the next digit of the answer. 
Result so far: 68266.09
If we subtract 7272 from 7700, we get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 11:
808 goes into 4280 5 times with a remainder of 240.
Use 5 as the next digit of our solution. 
Result so far: 68266.095
Subtracting 4040 from 4280 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 12:
2400 divided by 808 is 2 with a remainder of 784.
Record the quotient 2 as the next digit in the result. 
Result so far: 68266.0952
Subtracting 1616 from 2400 leaves us with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Going ahead to step 13:
When dividing 7840 by 808, we get 9 with a remainder of 568.
The next digit of our result is 9. 
Result so far: 68266.09529
The remainder is 568 after subtracting 7272 from 7840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Let's proceed to step 14:
808 can be fit into 5680 7 times, resulting in a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 68266.095297
Subtracting 5656 from 5680 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 15:
When dividing 240 by 808, we get 0 with a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 68266.095297
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 16:
If we divide 2400 by 808, we get 2 and a remainder of 784.
Record the quotient 2 as the next digit in the result. 
Result so far: 68266.09529702
If we subtract 1616 from 2400, we get 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

After the division, we end up with 68266.09529702 and a remainder of 7.84e-07.
