Let's divide 1880253 by 507
The aim is to understand the frequency of 507 in 1880253.

On to step 1:
507 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 507

Advancing to step 2:
18 divided by 507 is 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 507

Step 3:
507 can be fit into 188 0 times, resulting in a remainder of 188.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 188, we end up with 188.
Append the next digit (0) from the dividend to 188 and continue with: 1880 / 507

Step 4:
The number 507 fits into 1880 3 times, leaving a remainder of 359.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 1521 from 1880, we get 359.
Fetch the next digit (2) from the dividend, attach it to 359 and continue: 3592 / 507

Advancing to step 5:
If we divide 3592 by 507, we get 7 and a remainder of 43.
The next digit of our result is 7. 
Result so far: 37.0
If we take 3549 away from 3592, we end up with 43.
Grab the next digit (5) from the dividend, add it to 43, then carry on: 435 / 507

Going ahead to step 6:
If we divide 435 by 507, we get 0 and a remainder of 435.
The next digit of our result is 0. 
Result so far: 370.0
Deduct 0 from 435 and we're left with 435.
Grab the next digit (3) from the dividend, add it to 435, then carry on: 4353 / 507

Moving on to step 7:
507 goes into 4353 8 times with a remainder of 297.
The next digit of our result is 8. 
Result so far: 3708.0
Subtract 4056 from 4353 to get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Step 8:
When dividing 2970 by 507, we get 5 with a remainder of 435.
Write down 5 as next digit of the result. 
Result so far: 3708.5
Subtracting 2535 from 2970 leaves us with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Step 9:
507 goes into 4350 8 times with a remainder of 294.
Record the quotient 8 as the next digit in the result. 
Result so far: 3708.58
Subtracting 4056 from 4350 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

On to step 10:
When dividing 2940 by 507, we get 5 with a remainder of 405.
Record the quotient 5 as the next digit in the result. 
Result so far: 3708.585
If we subtract 2535 from 2940, we get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 11:
When dividing 4050 by 507, we get 7 with a remainder of 501.
Record the quotient 7 as the next digit in the result. 
Result so far: 3708.5857
The remainder is 501 after subtracting 3549 from 4050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Advancing to step 12:
When dividing 5010 by 507, we get 9 with a remainder of 447.
The next digit of our result is 9. 
Result so far: 3708.58579
If we take 4563 away from 5010, we end up with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Let's proceed to step 13:
The number 507 fits into 4470 8 times, leaving a remainder of 414.
Record the quotient 8 as the next digit in the result. 
Result so far: 3708.585798
Subtract 4056 from 4470 to get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Let's proceed to step 14:
4140 divided by 507 is 8 with a remainder of 84.
The next digit of our result is 8. 
Result so far: 3708.5857988
If we subtract 4056 from 4140, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final result is 3708.5857988 with a remainder of 8.4e-07.
