Let's divide 69138717 by 507
The aim is to understand the frequency of 507 in 69138717.

On to step 1:
507 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 507

Going ahead to step 2:
The number 507 fits into 69 0 times, leaving a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Include the next digit (1) from the dividend after 69, then repeat: 691 / 507

Step 3:
507 can be fit into 691 1 times, resulting in a remainder of 184.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 507 from 691 and we're left with 184.
Take the next digit (3) from the dividend and append it to 184, then repeat: 1843 / 507

Going ahead to step 4:
When dividing 1843 by 507, we get 3 with a remainder of 322.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 1521 from 1843 to get 322.
Take the next digit (8) from the dividend and append it to 322, then repeat: 3228 / 507

Going ahead to step 5:
507 can be fit into 3228 6 times, resulting in a remainder of 186.
Use 6 as the next digit of our solution. 
Result so far: 136.0
Subtract 3042 from 3228 to get 186.
Grab the next digit (7) from the dividend, add it to 186, then carry on: 1867 / 507

Moving on to step 6:
When dividing 1867 by 507, we get 3 with a remainder of 346.
Put 3 as the next digit of the answer. 
Result so far: 1363.0
Deduct 1521 from 1867 and we're left with 346.
Grab the next digit (1) from the dividend, add it to 346, then carry on: 3461 / 507

On to step 7:
When dividing 3461 by 507, we get 6 with a remainder of 419.
The next digit of our result is 6. 
Result so far: 13636.0
If we take 3042 away from 3461, we end up with 419.
Append the next digit (7) from the dividend to 419 and continue with: 4197 / 507

Let's proceed to step 8:
507 goes into 4197 8 times with a remainder of 141.
The next digit of our result is 8. 
Result so far: 136368.0
If we take 4056 away from 4197, we end up with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 9:
507 can be fit into 1410 2 times, resulting in a remainder of 396.
The number 2 becomes the next digit in our result. 
Result so far: 136368.2
The remainder is 396 after subtracting 1014 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 10:
3960 divided by 507 is 7 with a remainder of 411.
Record the quotient 7 as the next digit in the result. 
Result so far: 136368.27
The remainder is 411 after subtracting 3549 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Step 11:
The number 507 fits into 4110 8 times, leaving a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 136368.278
The remainder is 54 after subtracting 4056 from 4110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 12:
507 goes into 540 1 times with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 136368.2781
Subtracting 507 from 540 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 13:
507 can be fit into 330 0 times, resulting in a remainder of 330.
The number 0 becomes the next digit in our result. 
Result so far: 136368.2781
If we take 0 away from 330, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 14:
3300 divided by 507 is 6 with a remainder of 258.
Write down 6 as next digit of the result. 
Result so far: 136368.278106
Deduct 3042 from 3300 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 15:
507 goes into 2580 5 times with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 136368.2781065
Subtracting 2535 from 2580 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 16:
If we divide 450 by 507, we get 0 and a remainder of 450.
Record the quotient 0 as the next digit in the result. 
Result so far: 136368.2781065
Subtract 0 from 450 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

In conclusion, the division gives 136368.2781065 with a balance of 4.5e-07.
