We divide 66985575 by 985
The aim is to understand the frequency of 985 in 66985575.

Let's proceed to step 1:
The number 985 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 985

Advancing to step 2:
66 divided by 985 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (9) from the dividend to 66 and continue with: 669 / 985

Going ahead to step 3:
If we divide 669 by 985, we get 0 and a remainder of 669.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 669 to get 669.
Include the next digit (8) from the dividend after 669, then repeat: 6698 / 985

On to step 4:
When dividing 6698 by 985, we get 6 with a remainder of 788.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 5910 from 6698 to get 788.
Fetch the next digit (5) from the dividend, attach it to 788 and continue: 7885 / 985

Advancing to step 5:
985 goes into 7885 8 times with a remainder of 5.
The next digit of our result is 8. 
Result so far: 68.0
Deduct 7880 from 7885 and we're left with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 985

Step 6:
When dividing 55 by 985, we get 0 with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 680.0
If we subtract 0 from 55, we get 55.
Fetch the next digit (7) from the dividend, attach it to 55 and continue: 557 / 985

On to step 7:
If we divide 557 by 985, we get 0 and a remainder of 557.
Use 0 as the next digit of our solution. 
Result so far: 6800.0
If we subtract 0 from 557, we get 557.
Take the next digit (5) from the dividend and append it to 557, then repeat: 5575 / 985

Let's proceed to step 8:
When dividing 5575 by 985, we get 5 with a remainder of 650.
The next digit of our result is 5. 
Result so far: 68005.0
Deduct 4925 from 5575 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Step 9:
985 can be fit into 6500 6 times, resulting in a remainder of 590.
Record the quotient 6 as the next digit in the result. 
Result so far: 68005.6
Subtract 5910 from 6500 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Advancing to step 10:
If we divide 5900 by 985, we get 5 and a remainder of 975.
The next digit of our result is 5. 
Result so far: 68005.65
Subtracting 4925 from 5900 leaves us with 975.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9750, and continue the process.

Step 11:
985 can be fit into 9750 9 times, resulting in a remainder of 885.
Write down 9 as next digit of the result. 
Result so far: 68005.659
Deduct 8865 from 9750 and we're left with 885.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8850, and continue the process.

On to step 12:
985 goes into 8850 8 times with a remainder of 970.
Use 8 as the next digit of our solution. 
Result so far: 68005.6598
Subtract 7880 from 8850 to get 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9700, and continue the process.

On to step 13:
When dividing 9700 by 985, we get 9 with a remainder of 835.
Record the quotient 9 as the next digit in the result. 
Result so far: 68005.65989
If we take 8865 away from 9700, we end up with 835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

Moving on to step 14:
If we divide 8350 by 985, we get 8 and a remainder of 470.
Put 8 as the next digit of the answer. 
Result so far: 68005.659898
The remainder is 470 after subtracting 7880 from 8350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 15:
985 goes into 4700 4 times with a remainder of 760.
Use 4 as the next digit of our solution. 
Result so far: 68005.6598984
The remainder is 760 after subtracting 3940 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 16:
When dividing 7600 by 985, we get 7 with a remainder of 705.
Use 7 as the next digit of our solution. 
Result so far: 68005.65989847
If we subtract 6895 from 7600, we get 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

After the division, we end up with 68005.65989847 and a remainder of 7.05e-07.
