We divide 55215961 by 508
The aim is to understand the frequency of 508 in 55215961.

On to step 1:
If we divide 5 by 508, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 508

Moving on to step 2:
508 goes into 55 0 times with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Append the next digit (2) from the dividend to 55 and continue with: 552 / 508

Going ahead to step 3:
The number 508 fits into 552 1 times, leaving a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 508 away from 552, we end up with 44.
Bring next digit (1) of the dividend behind the 44 and repeat the process: 441 / 508

Let's proceed to step 4:
The number 508 fits into 441 0 times, leaving a remainder of 441.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 441 leaves us with 441.
Fetch the next digit (5) from the dividend, attach it to 441 and continue: 4415 / 508

Advancing to step 5:
508 can be fit into 4415 8 times, resulting in a remainder of 351.
Put 8 as the next digit of the answer. 
Result so far: 108.0
If we subtract 4064 from 4415, we get 351.
Fetch the next digit (9) from the dividend, attach it to 351 and continue: 3519 / 508

Step 6:
508 can be fit into 3519 6 times, resulting in a remainder of 471.
The number 6 becomes the next digit in our result. 
Result so far: 1086.0
If we take 3048 away from 3519, we end up with 471.
Include the next digit (6) from the dividend after 471, then repeat: 4716 / 508

On to step 7:
508 can be fit into 4716 9 times, resulting in a remainder of 144.
The number 9 becomes the next digit in our result. 
Result so far: 10869.0
Subtracting 4572 from 4716 leaves us with 144.
Fetch the next digit (1) from the dividend, attach it to 144 and continue: 1441 / 508

On to step 8:
1441 divided by 508 is 2 with a remainder of 425.
Use 2 as the next digit of our solution. 
Result so far: 108692.0
The remainder is 425 after subtracting 1016 from 1441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Advancing to step 9:
508 goes into 4250 8 times with a remainder of 186.
The next digit of our result is 8. 
Result so far: 108692.8
Deduct 4064 from 4250 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 10:
If we divide 1860 by 508, we get 3 and a remainder of 336.
The number 3 becomes the next digit in our result. 
Result so far: 108692.83
Deduct 1524 from 1860 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 11:
The number 508 fits into 3360 6 times, leaving a remainder of 312.
The next digit of our result is 6. 
Result so far: 108692.836
Deduct 3048 from 3360 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 12:
The number 508 fits into 3120 6 times, leaving a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 108692.8366
Subtract 3048 from 3120 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 108692.8366 and a remainder of 0.00072.
