Let's divide 13991169 by 508
The aim is to understand the frequency of 508 in 13991169.

Going ahead to step 1:
If we divide 1 by 508, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 508

Step 2:
508 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 508

Step 3:
508 goes into 139 0 times with a remainder of 139.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 139 leaves us with 139.
Fetch the next digit (9) from the dividend, attach it to 139 and continue: 1399 / 508

Going ahead to step 4:
The number 508 fits into 1399 2 times, leaving a remainder of 383.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1016 from 1399 and we're left with 383.
Grab the next digit (1) from the dividend, add it to 383, then carry on: 3831 / 508

On to step 5:
3831 divided by 508 is 7 with a remainder of 275.
The next digit of our result is 7. 
Result so far: 27.0
Deduct 3556 from 3831 and we're left with 275.
Fetch the next digit (1) from the dividend, attach it to 275 and continue: 2751 / 508

Moving on to step 6:
When dividing 2751 by 508, we get 5 with a remainder of 211.
The next digit of our result is 5. 
Result so far: 275.0
If we take 2540 away from 2751, we end up with 211.
Include the next digit (6) from the dividend after 211, then repeat: 2116 / 508

Moving on to step 7:
If we divide 2116 by 508, we get 4 and a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 2754.0
Subtracting 2032 from 2116 leaves us with 84.
Include the next digit (9) from the dividend after 84, then repeat: 849 / 508

Let's proceed to step 8:
When dividing 849 by 508, we get 1 with a remainder of 341.
The next digit of our result is 1. 
Result so far: 27541.0
The remainder is 341 after subtracting 508 from 849.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Moving on to step 9:
If we divide 3410 by 508, we get 6 and a remainder of 362.
The next digit of our result is 6. 
Result so far: 27541.6
The remainder is 362 after subtracting 3048 from 3410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 10:
If we divide 3620 by 508, we get 7 and a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 27541.67
Subtracting 3556 from 3620 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 11:
If we divide 640 by 508, we get 1 and a remainder of 132.
Use 1 as the next digit of our solution. 
Result so far: 27541.671
Subtracting 508 from 640 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 12:
When dividing 1320 by 508, we get 2 with a remainder of 304.
Use 2 as the next digit of our solution. 
Result so far: 27541.6712
Subtract 1016 from 1320 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 13:
The number 508 fits into 3040 5 times, leaving a remainder of 500.
The number 5 becomes the next digit in our result. 
Result so far: 27541.67125
Subtract 2540 from 3040 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 14:
The number 508 fits into 5000 9 times, leaving a remainder of 428.
Put 9 as the next digit of the answer. 
Result so far: 27541.671259
Deduct 4572 from 5000 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Advancing to step 15:
If we divide 4280 by 508, we get 8 and a remainder of 216.
The next digit of our result is 8. 
Result so far: 27541.6712598
Subtract 4064 from 4280 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 16:
508 goes into 2160 4 times with a remainder of 128.
Use 4 as the next digit of our solution. 
Result so far: 27541.67125984
If we take 2032 away from 2160, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

In conclusion, the division gives 27541.67125984 with a balance of 1.28e-07.
