Let's divide 55770387 by 587
The aim is to understand the frequency of 587 in 55770387.

Advancing to step 1:
The number 587 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 587

Step 2:
The number 587 fits into 55 0 times, leaving a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Fetch the next digit (7) from the dividend, attach it to 55 and continue: 557 / 587

Let's proceed to step 3:
557 divided by 587 is 0 with a remainder of 557.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 557 and we're left with 557.
Bring next digit (7) of the dividend behind the 557 and repeat the process: 5577 / 587

Step 4:
587 can be fit into 5577 9 times, resulting in a remainder of 294.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 5283 from 5577 to get 294.
Take the next digit (0) from the dividend and append it to 294, then repeat: 2940 / 587

On to step 5:
587 can be fit into 2940 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 95.0
Deduct 2935 from 2940 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 587

On to step 6:
587 goes into 53 0 times with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 950.0
Subtracting 0 from 53 leaves us with 53.
Grab the next digit (8) from the dividend, add it to 53, then carry on: 538 / 587

Going ahead to step 7:
538 divided by 587 is 0 with a remainder of 538.
Put 0 as the next digit of the answer. 
Result so far: 9500.0
If we subtract 0 from 538, we get 538.
Bring next digit (7) of the dividend behind the 538 and repeat the process: 5387 / 587

Going ahead to step 8:
The number 587 fits into 5387 9 times, leaving a remainder of 104.
The number 9 becomes the next digit in our result. 
Result so far: 95009.0
If we take 5283 away from 5387, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 9:
If we divide 1040 by 587, we get 1 and a remainder of 453.
Write down 1 as next digit of the result. 
Result so far: 95009.1
If we subtract 587 from 1040, we get 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Moving on to step 10:
If we divide 4530 by 587, we get 7 and a remainder of 421.
The next digit of our result is 7. 
Result so far: 95009.17
Subtracting 4109 from 4530 leaves us with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Advancing to step 11:
If we divide 4210 by 587, we get 7 and a remainder of 101.
Use 7 as the next digit of our solution. 
Result so far: 95009.177
Deduct 4109 from 4210 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

The final outcome is 95009.177, with a leftover of 0.0101.
