We divide 67540281 by 660
The aim is to understand the frequency of 660 in 67540281.

Going ahead to step 1:
When dividing 6 by 660, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 660

Going ahead to step 2:
660 goes into 67 0 times with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Append the next digit (5) from the dividend to 67 and continue with: 675 / 660

Advancing to step 3:
The number 660 fits into 675 1 times, leaving a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
If we take 660 away from 675, we end up with 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 660

Step 4:
154 divided by 660 is 0 with a remainder of 154.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 154, we get 154.
Fetch the next digit (0) from the dividend, attach it to 154 and continue: 1540 / 660

Step 5:
The number 660 fits into 1540 2 times, leaving a remainder of 220.
The next digit of our result is 2. 
Result so far: 102.0
Subtracting 1320 from 1540 leaves us with 220.
Append the next digit (2) from the dividend to 220 and continue with: 2202 / 660

Let's proceed to step 6:
When dividing 2202 by 660, we get 3 with a remainder of 222.
The number 3 becomes the next digit in our result. 
Result so far: 1023.0
Subtracting 1980 from 2202 leaves us with 222.
Fetch the next digit (8) from the dividend, attach it to 222 and continue: 2228 / 660

Going ahead to step 7:
2228 divided by 660 is 3 with a remainder of 248.
Use 3 as the next digit of our solution. 
Result so far: 10233.0
The remainder is 248 after subtracting 1980 from 2228.
Grab the next digit (1) from the dividend, add it to 248, then carry on: 2481 / 660

Going ahead to step 8:
The number 660 fits into 2481 3 times, leaving a remainder of 501.
Record the quotient 3 as the next digit in the result. 
Result so far: 102333.0
If we take 1980 away from 2481, we end up with 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Step 9:
When dividing 5010 by 660, we get 7 with a remainder of 390.
Put 7 as the next digit of the answer. 
Result so far: 102333.7
The remainder is 390 after subtracting 4620 from 5010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 10:
When dividing 3900 by 660, we get 5 with a remainder of 600.
The number 5 becomes the next digit in our result. 
Result so far: 102333.75
If we take 3300 away from 3900, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 11:
When dividing 6000 by 660, we get 9 with a remainder of 60.
The next digit of our result is 9. 
Result so far: 102333.759
If we subtract 5940 from 6000, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
660 can be fit into 600 0 times, resulting in a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 102333.759
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 13:
The number 660 fits into 6000 9 times, leaving a remainder of 60.
Write down 9 as next digit of the result. 
Result so far: 102333.75909
If we take 5940 away from 6000, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 14:
660 can be fit into 600 0 times, resulting in a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 102333.75909
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 15:
660 can be fit into 6000 9 times, resulting in a remainder of 60.
Use 9 as the next digit of our solution. 
Result so far: 102333.7590909
If we take 5940 away from 6000, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 16:
660 can be fit into 600 0 times, resulting in a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 102333.7590909
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final result is 102333.7590909 with a remainder of 6e-07.
