We're dividing 87757064 by 660 
The aim is to understand the frequency of 660 in 87757064.

Going ahead to step 1:
660 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 660

Step 2:
The number 660 fits into 87 0 times, leaving a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Grab the next digit (7) from the dividend, add it to 87, then carry on: 877 / 660

Let's proceed to step 3:
When dividing 877 by 660, we get 1 with a remainder of 217.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 660 from 877 to get 217.
Fetch the next digit (5) from the dividend, attach it to 217 and continue: 2175 / 660

Moving on to step 4:
660 can be fit into 2175 3 times, resulting in a remainder of 195.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 1980 away from 2175, we end up with 195.
Fetch the next digit (7) from the dividend, attach it to 195 and continue: 1957 / 660

Step 5:
1957 divided by 660 is 2 with a remainder of 637.
Put 2 as the next digit of the answer. 
Result so far: 132.0
The remainder is 637 after subtracting 1320 from 1957.
Grab the next digit (0) from the dividend, add it to 637, then carry on: 6370 / 660

Let's proceed to step 6:
6370 divided by 660 is 9 with a remainder of 430.
The next digit of our result is 9. 
Result so far: 1329.0
Subtract 5940 from 6370 to get 430.
Include the next digit (6) from the dividend after 430, then repeat: 4306 / 660

Step 7:
4306 divided by 660 is 6 with a remainder of 346.
The next digit of our result is 6. 
Result so far: 13296.0
If we take 3960 away from 4306, we end up with 346.
Append the next digit (4) from the dividend to 346 and continue with: 3464 / 660

Going ahead to step 8:
The number 660 fits into 3464 5 times, leaving a remainder of 164.
The next digit of our result is 5. 
Result so far: 132965.0
If we subtract 3300 from 3464, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 9:
When dividing 1640 by 660, we get 2 with a remainder of 320.
Put 2 as the next digit of the answer. 
Result so far: 132965.2
Subtracting 1320 from 1640 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 10:
When dividing 3200 by 660, we get 4 with a remainder of 560.
Write down 4 as next digit of the result. 
Result so far: 132965.24
Subtract 2640 from 3200 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 11:
5600 divided by 660 is 8 with a remainder of 320.
The next digit of our result is 8. 
Result so far: 132965.248
If we take 5280 away from 5600, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 12:
The number 660 fits into 3200 4 times, leaving a remainder of 560.
The number 4 becomes the next digit in our result. 
Result so far: 132965.2484
Subtract 2640 from 3200 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 13:
660 can be fit into 5600 8 times, resulting in a remainder of 320.
The number 8 becomes the next digit in our result. 
Result so far: 132965.24848
Subtract 5280 from 5600 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 14:
The number 660 fits into 3200 4 times, leaving a remainder of 560.
Record the quotient 4 as the next digit in the result. 
Result so far: 132965.248484
If we take 2640 away from 3200, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 15:
5600 divided by 660 is 8 with a remainder of 320.
Write down 8 as next digit of the result. 
Result so far: 132965.2484848
Deduct 5280 from 5600 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 16:
If we divide 3200 by 660, we get 4 and a remainder of 560.
Use 4 as the next digit of our solution. 
Result so far: 132965.24848484
The remainder is 560 after subtracting 2640 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

After the division, we end up with 132965.24848484 and a remainder of 5.6e-07.
