We're dividing 64660880 by 785 
The aim is to understand the frequency of 785 in 64660880.

Advancing to step 1:
785 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 785

Step 2:
64 divided by 785 is 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Append the next digit (6) from the dividend to 64 and continue with: 646 / 785

Step 3:
785 can be fit into 646 0 times, resulting in a remainder of 646.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 646, we get 646.
Take the next digit (6) from the dividend and append it to 646, then repeat: 6466 / 785

Step 4:
If we divide 6466 by 785, we get 8 and a remainder of 186.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 6280 from 6466 to get 186.
Grab the next digit (0) from the dividend, add it to 186, then carry on: 1860 / 785

On to step 5:
1860 divided by 785 is 2 with a remainder of 290.
Put 2 as the next digit of the answer. 
Result so far: 82.0
Subtract 1570 from 1860 to get 290.
Grab the next digit (8) from the dividend, add it to 290, then carry on: 2908 / 785

Advancing to step 6:
785 goes into 2908 3 times with a remainder of 553.
The number 3 becomes the next digit in our result. 
Result so far: 823.0
If we subtract 2355 from 2908, we get 553.
Grab the next digit (8) from the dividend, add it to 553, then carry on: 5538 / 785

Going ahead to step 7:
The number 785 fits into 5538 7 times, leaving a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 8237.0
If we subtract 5495 from 5538, we get 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 785

On to step 8:
If we divide 430 by 785, we get 0 and a remainder of 430.
Put 0 as the next digit of the answer. 
Result so far: 82370.0
Subtracting 0 from 430 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 9:
The number 785 fits into 4300 5 times, leaving a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 82370.5
Subtracting 3925 from 4300 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 10:
The number 785 fits into 3750 4 times, leaving a remainder of 610.
Record the quotient 4 as the next digit in the result. 
Result so far: 82370.54
Subtracting 3140 from 3750 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Moving on to step 11:
785 goes into 6100 7 times with a remainder of 605.
The next digit of our result is 7. 
Result so far: 82370.547
If we take 5495 away from 6100, we end up with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Going ahead to step 12:
When dividing 6050 by 785, we get 7 with a remainder of 555.
The number 7 becomes the next digit in our result. 
Result so far: 82370.5477
Subtract 5495 from 6050 to get 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

The final result is 82370.5477 with a remainder of 0.00555.
