We look at the division of 43717682 by 508 
The aim is to understand the frequency of 508 in 43717682.

Step 1:
508 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 508

Going ahead to step 2:
508 goes into 43 0 times with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Take the next digit (7) from the dividend and append it to 43, then repeat: 437 / 508

Moving on to step 3:
508 goes into 437 0 times with a remainder of 437.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 437 and we're left with 437.
Fetch the next digit (1) from the dividend, attach it to 437 and continue: 4371 / 508

On to step 4:
508 can be fit into 4371 8 times, resulting in a remainder of 307.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 307 after subtracting 4064 from 4371.
Append the next digit (7) from the dividend to 307 and continue with: 3077 / 508

Advancing to step 5:
The number 508 fits into 3077 6 times, leaving a remainder of 29.
Write down 6 as next digit of the result. 
Result so far: 86.0
Deduct 3048 from 3077 and we're left with 29.
Include the next digit (6) from the dividend after 29, then repeat: 296 / 508

Going ahead to step 6:
296 divided by 508 is 0 with a remainder of 296.
The number 0 becomes the next digit in our result. 
Result so far: 860.0
If we subtract 0 from 296, we get 296.
Fetch the next digit (8) from the dividend, attach it to 296 and continue: 2968 / 508

Advancing to step 7:
The number 508 fits into 2968 5 times, leaving a remainder of 428.
Put 5 as the next digit of the answer. 
Result so far: 8605.0
If we subtract 2540 from 2968, we get 428.
Include the next digit (2) from the dividend after 428, then repeat: 4282 / 508

Step 8:
If we divide 4282 by 508, we get 8 and a remainder of 218.
The next digit of our result is 8. 
Result so far: 86058.0
If we take 4064 away from 4282, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 9:
508 goes into 2180 4 times with a remainder of 148.
Write down 4 as next digit of the result. 
Result so far: 86058.4
If we subtract 2032 from 2180, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 10:
When dividing 1480 by 508, we get 2 with a remainder of 464.
Record the quotient 2 as the next digit in the result. 
Result so far: 86058.42
If we take 1016 away from 1480, we end up with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Advancing to step 11:
When dividing 4640 by 508, we get 9 with a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 86058.429
If we subtract 4572 from 4640, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 12:
If we divide 680 by 508, we get 1 and a remainder of 172.
Record the quotient 1 as the next digit in the result. 
Result so far: 86058.4291
If we subtract 508 from 680, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 13:
508 can be fit into 1720 3 times, resulting in a remainder of 196.
The next digit of our result is 3. 
Result so far: 86058.42913
If we take 1524 away from 1720, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 14:
1960 divided by 508 is 3 with a remainder of 436.
The number 3 becomes the next digit in our result. 
Result so far: 86058.429133
Subtracting 1524 from 1960 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

After the division, we end up with 86058.429133 and a remainder of 4.36e-05.
