We're dividing 68600253 by 507 
The aim is to understand the frequency of 507 in 68600253.

Advancing to step 1:
If we divide 6 by 507, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 507

On to step 2:
68 divided by 507 is 0 with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Fetch the next digit (6) from the dividend, attach it to 68 and continue: 686 / 507

Advancing to step 3:
If we divide 686 by 507, we get 1 and a remainder of 179.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 507 from 686 to get 179.
Bring next digit (0) of the dividend behind the 179 and repeat the process: 1790 / 507

Moving on to step 4:
1790 divided by 507 is 3 with a remainder of 269.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 1521 from 1790 leaves us with 269.
Include the next digit (0) from the dividend after 269, then repeat: 2690 / 507

Let's proceed to step 5:
507 can be fit into 2690 5 times, resulting in a remainder of 155.
The next digit of our result is 5. 
Result so far: 135.0
If we subtract 2535 from 2690, we get 155.
Include the next digit (2) from the dividend after 155, then repeat: 1552 / 507

Step 6:
1552 divided by 507 is 3 with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 1353.0
If we subtract 1521 from 1552, we get 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 507

Going ahead to step 7:
When dividing 315 by 507, we get 0 with a remainder of 315.
Write down 0 as next digit of the result. 
Result so far: 13530.0
Deduct 0 from 315 and we're left with 315.
Grab the next digit (3) from the dividend, add it to 315, then carry on: 3153 / 507

On to step 8:
If we divide 3153 by 507, we get 6 and a remainder of 111.
Record the quotient 6 as the next digit in the result. 
Result so far: 135306.0
Subtracting 3042 from 3153 leaves us with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 9:
1110 divided by 507 is 2 with a remainder of 96.
Record the quotient 2 as the next digit in the result. 
Result so far: 135306.2
The remainder is 96 after subtracting 1014 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 10:
The number 507 fits into 960 1 times, leaving a remainder of 453.
Use 1 as the next digit of our solution. 
Result so far: 135306.21
Deduct 507 from 960 and we're left with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Advancing to step 11:
When dividing 4530 by 507, we get 8 with a remainder of 474.
Record the quotient 8 as the next digit in the result. 
Result so far: 135306.218
Subtracting 4056 from 4530 leaves us with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

On to step 12:
If we divide 4740 by 507, we get 9 and a remainder of 177.
Use 9 as the next digit of our solution. 
Result so far: 135306.2189
Subtracting 4563 from 4740 leaves us with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Let's proceed to step 13:
When dividing 1770 by 507, we get 3 with a remainder of 249.
The next digit of our result is 3. 
Result so far: 135306.21893
The remainder is 249 after subtracting 1521 from 1770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Moving on to step 14:
507 can be fit into 2490 4 times, resulting in a remainder of 462.
Put 4 as the next digit of the answer. 
Result so far: 135306.218934
Subtract 2028 from 2490 to get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Moving on to step 15:
When dividing 4620 by 507, we get 9 with a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 135306.2189349
The remainder is 57 after subtracting 4563 from 4620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 16:
The number 507 fits into 570 1 times, leaving a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 135306.21893491
If we subtract 507 from 570, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Our division results in 135306.21893491 with a remaining 6.3e-08.
