We look at the division of 30528551 by 507 
The aim is to understand the frequency of 507 in 30528551.

Going ahead to step 1:
3 divided by 507 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 507

Advancing to step 2:
If we divide 30 by 507, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (5) from the dividend, attach it to 30 and continue: 305 / 507

Going ahead to step 3:
305 divided by 507 is 0 with a remainder of 305.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 305 and we're left with 305.
Grab the next digit (2) from the dividend, add it to 305, then carry on: 3052 / 507

Step 4:
507 can be fit into 3052 6 times, resulting in a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 3042 from 3052 to get 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 507

Let's proceed to step 5:
The number 507 fits into 108 0 times, leaving a remainder of 108.
Use 0 as the next digit of our solution. 
Result so far: 60.0
Deduct 0 from 108 and we're left with 108.
Bring next digit (5) of the dividend behind the 108 and repeat the process: 1085 / 507

On to step 6:
The number 507 fits into 1085 2 times, leaving a remainder of 71.
Record the quotient 2 as the next digit in the result. 
Result so far: 602.0
Deduct 1014 from 1085 and we're left with 71.
Grab the next digit (5) from the dividend, add it to 71, then carry on: 715 / 507

On to step 7:
715 divided by 507 is 1 with a remainder of 208.
The number 1 becomes the next digit in our result. 
Result so far: 6021.0
Subtract 507 from 715 to get 208.
Bring next digit (1) of the dividend behind the 208 and repeat the process: 2081 / 507

Advancing to step 8:
507 goes into 2081 4 times with a remainder of 53.
Use 4 as the next digit of our solution. 
Result so far: 60214.0
If we take 2028 away from 2081, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 9:
If we divide 530 by 507, we get 1 and a remainder of 23.
The next digit of our result is 1. 
Result so far: 60214.1
The remainder is 23 after subtracting 507 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 10:
The number 507 fits into 230 0 times, leaving a remainder of 230.
Use 0 as the next digit of our solution. 
Result so far: 60214.1
If we subtract 0 from 230, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 11:
507 can be fit into 2300 4 times, resulting in a remainder of 272.
The next digit of our result is 4. 
Result so far: 60214.104
If we subtract 2028 from 2300, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 12:
507 goes into 2720 5 times with a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 60214.1045
Deduct 2535 from 2720 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 13:
507 can be fit into 1850 3 times, resulting in a remainder of 329.
Use 3 as the next digit of our solution. 
Result so far: 60214.10453
If we take 1521 away from 1850, we end up with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Let's proceed to step 14:
3290 divided by 507 is 6 with a remainder of 248.
Record the quotient 6 as the next digit in the result. 
Result so far: 60214.104536
If we subtract 3042 from 3290, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 15:
When dividing 2480 by 507, we get 4 with a remainder of 452.
The next digit of our result is 4. 
Result so far: 60214.1045364
Subtract 2028 from 2480 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Let's proceed to step 16:
507 can be fit into 4520 8 times, resulting in a remainder of 464.
Record the quotient 8 as the next digit in the result. 
Result so far: 60214.10453648
The remainder is 464 after subtracting 4056 from 4520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

The quotient of the division is 60214.10453648, and the remainder is 4.64e-07.
