38939311 ÷ 507 
The aim is to understand the frequency of 507 in 38939311.

Moving on to step 1:
The number 507 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 507

Step 2:
When dividing 38 by 507, we get 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Take the next digit (9) from the dividend and append it to 38, then repeat: 389 / 507

Going ahead to step 3:
389 divided by 507 is 0 with a remainder of 389.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 389 and we're left with 389.
Grab the next digit (3) from the dividend, add it to 389, then carry on: 3893 / 507

Going ahead to step 4:
If we divide 3893 by 507, we get 7 and a remainder of 344.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 3549 from 3893, we get 344.
Grab the next digit (9) from the dividend, add it to 344, then carry on: 3449 / 507

Advancing to step 5:
When dividing 3449 by 507, we get 6 with a remainder of 407.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
The remainder is 407 after subtracting 3042 from 3449.
Append the next digit (3) from the dividend to 407 and continue with: 4073 / 507

Advancing to step 6:
The number 507 fits into 4073 8 times, leaving a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 768.0
If we take 4056 away from 4073, we end up with 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 507

Moving on to step 7:
If we divide 171 by 507, we get 0 and a remainder of 171.
The next digit of our result is 0. 
Result so far: 7680.0
Subtract 0 from 171 to get 171.
Append the next digit (1) from the dividend to 171 and continue with: 1711 / 507

Going ahead to step 8:
507 goes into 1711 3 times with a remainder of 190.
The number 3 becomes the next digit in our result. 
Result so far: 76803.0
The remainder is 190 after subtracting 1521 from 1711.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 9:
1900 divided by 507 is 3 with a remainder of 379.
Use 3 as the next digit of our solution. 
Result so far: 76803.3
Deduct 1521 from 1900 and we're left with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Let's proceed to step 10:
507 goes into 3790 7 times with a remainder of 241.
Use 7 as the next digit of our solution. 
Result so far: 76803.37
If we subtract 3549 from 3790, we get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

On to step 11:
If we divide 2410 by 507, we get 4 and a remainder of 382.
The number 4 becomes the next digit in our result. 
Result so far: 76803.374
Subtract 2028 from 2410 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Moving on to step 12:
507 can be fit into 3820 7 times, resulting in a remainder of 271.
Record the quotient 7 as the next digit in the result. 
Result so far: 76803.3747
The remainder is 271 after subtracting 3549 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Step 13:
507 goes into 2710 5 times with a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 76803.37475
Subtracting 2535 from 2710 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 14:
The number 507 fits into 1750 3 times, leaving a remainder of 229.
Put 3 as the next digit of the answer. 
Result so far: 76803.374753
The remainder is 229 after subtracting 1521 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Moving on to step 15:
When dividing 2290 by 507, we get 4 with a remainder of 262.
Record the quotient 4 as the next digit in the result. 
Result so far: 76803.3747534
Deduct 2028 from 2290 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 16:
The number 507 fits into 2620 5 times, leaving a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 76803.37475345
If we subtract 2535 from 2620, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The quotient of the division is 76803.37475345, and the remainder is 8.5e-08.
