75610577 ÷ 387 
The aim is to understand the frequency of 387 in 75610577.

Moving on to step 1:
If we divide 7 by 387, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 387

Moving on to step 2:
387 can be fit into 75 0 times, resulting in a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Bring next digit (6) of the dividend behind the 75 and repeat the process: 756 / 387

Advancing to step 3:
756 divided by 387 is 1 with a remainder of 369.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 387 from 756 leaves us with 369.
Take the next digit (1) from the dividend and append it to 369, then repeat: 3691 / 387

Let's proceed to step 4:
387 goes into 3691 9 times with a remainder of 208.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 3483 from 3691 and we're left with 208.
Take the next digit (0) from the dividend and append it to 208, then repeat: 2080 / 387

Step 5:
387 can be fit into 2080 5 times, resulting in a remainder of 145.
The next digit of our result is 5. 
Result so far: 195.0
If we take 1935 away from 2080, we end up with 145.
Grab the next digit (5) from the dividend, add it to 145, then carry on: 1455 / 387

Going ahead to step 6:
When dividing 1455 by 387, we get 3 with a remainder of 294.
Use 3 as the next digit of our solution. 
Result so far: 1953.0
Subtracting 1161 from 1455 leaves us with 294.
Fetch the next digit (7) from the dividend, attach it to 294 and continue: 2947 / 387

Advancing to step 7:
2947 divided by 387 is 7 with a remainder of 238.
Record the quotient 7 as the next digit in the result. 
Result so far: 19537.0
Subtracting 2709 from 2947 leaves us with 238.
Include the next digit (7) from the dividend after 238, then repeat: 2387 / 387

Advancing to step 8:
387 goes into 2387 6 times with a remainder of 65.
Record the quotient 6 as the next digit in the result. 
Result so far: 195376.0
Subtracting 2322 from 2387 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 9:
387 can be fit into 650 1 times, resulting in a remainder of 263.
Record the quotient 1 as the next digit in the result. 
Result so far: 195376.1
Subtracting 387 from 650 leaves us with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Moving on to step 10:
387 goes into 2630 6 times with a remainder of 308.
The number 6 becomes the next digit in our result. 
Result so far: 195376.16
Subtract 2322 from 2630 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 11:
If we divide 3080 by 387, we get 7 and a remainder of 371.
Use 7 as the next digit of our solution. 
Result so far: 195376.167
The remainder is 371 after subtracting 2709 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

On to step 12:
387 can be fit into 3710 9 times, resulting in a remainder of 227.
Put 9 as the next digit of the answer. 
Result so far: 195376.1679
If we take 3483 away from 3710, we end up with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Let's proceed to step 13:
When dividing 2270 by 387, we get 5 with a remainder of 335.
Write down 5 as next digit of the result. 
Result so far: 195376.16795
Subtract 1935 from 2270 to get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 14:
The number 387 fits into 3350 8 times, leaving a remainder of 254.
The number 8 becomes the next digit in our result. 
Result so far: 195376.167958
Subtract 3096 from 3350 to get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Let's proceed to step 15:
2540 divided by 387 is 6 with a remainder of 218.
The number 6 becomes the next digit in our result. 
Result so far: 195376.1679586
If we take 2322 away from 2540, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 16:
If we divide 2180 by 387, we get 5 and a remainder of 245.
Use 5 as the next digit of our solution. 
Result so far: 195376.16795865
If we subtract 1935 from 2180, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

After the division, we end up with 195376.16795865 and a remainder of 2.45e-07.
