75945915 divided by 508 
The aim is to understand the frequency of 508 in 75945915.

On to step 1:
508 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 508

On to step 2:
If we divide 75 by 508, we get 0 and a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Bring next digit (9) of the dividend behind the 75 and repeat the process: 759 / 508

Advancing to step 3:
The number 508 fits into 759 1 times, leaving a remainder of 251.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 508 from 759 to get 251.
Append the next digit (4) from the dividend to 251 and continue with: 2514 / 508

On to step 4:
508 goes into 2514 4 times with a remainder of 482.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 482 after subtracting 2032 from 2514.
Grab the next digit (5) from the dividend, add it to 482, then carry on: 4825 / 508

Step 5:
When dividing 4825 by 508, we get 9 with a remainder of 253.
The number 9 becomes the next digit in our result. 
Result so far: 149.0
If we take 4572 away from 4825, we end up with 253.
Include the next digit (9) from the dividend after 253, then repeat: 2539 / 508

Moving on to step 6:
If we divide 2539 by 508, we get 4 and a remainder of 507.
The next digit of our result is 4. 
Result so far: 1494.0
The remainder is 507 after subtracting 2032 from 2539.
Include the next digit (1) from the dividend after 507, then repeat: 5071 / 508

Step 7:
5071 divided by 508 is 9 with a remainder of 499.
Use 9 as the next digit of our solution. 
Result so far: 14949.0
Subtract 4572 from 5071 to get 499.
Append the next digit (5) from the dividend to 499 and continue with: 4995 / 508

Going ahead to step 8:
4995 divided by 508 is 9 with a remainder of 423.
The number 9 becomes the next digit in our result. 
Result so far: 149499.0
Deduct 4572 from 4995 and we're left with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Going ahead to step 9:
If we divide 4230 by 508, we get 8 and a remainder of 166.
Put 8 as the next digit of the answer. 
Result so far: 149499.8
Deduct 4064 from 4230 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 10:
The number 508 fits into 1660 3 times, leaving a remainder of 136.
Write down 3 as next digit of the result. 
Result so far: 149499.83
If we subtract 1524 from 1660, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 11:
The number 508 fits into 1360 2 times, leaving a remainder of 344.
Record the quotient 2 as the next digit in the result. 
Result so far: 149499.832
If we take 1016 away from 1360, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 12:
When dividing 3440 by 508, we get 6 with a remainder of 392.
Write down 6 as next digit of the result. 
Result so far: 149499.8326
Deduct 3048 from 3440 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 13:
508 goes into 3920 7 times with a remainder of 364.
The next digit of our result is 7. 
Result so far: 149499.83267
If we take 3556 away from 3920, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 14:
If we divide 3640 by 508, we get 7 and a remainder of 84.
Use 7 as the next digit of our solution. 
Result so far: 149499.832677
The remainder is 84 after subtracting 3556 from 3640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

After the division, we end up with 149499.832677 and a remainder of 8.4e-06.
