55964617 ÷ 987 
The aim is to understand the frequency of 987 in 55964617.

Advancing to step 1:
987 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 987

Moving on to step 2:
55 divided by 987 is 0 with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Take the next digit (9) from the dividend and append it to 55, then repeat: 559 / 987

Step 3:
987 goes into 559 0 times with a remainder of 559.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 559 to get 559.
Fetch the next digit (6) from the dividend, attach it to 559 and continue: 5596 / 987

Let's proceed to step 4:
5596 divided by 987 is 5 with a remainder of 661.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 4935 away from 5596, we end up with 661.
Bring next digit (4) of the dividend behind the 661 and repeat the process: 6614 / 987

Moving on to step 5:
The number 987 fits into 6614 6 times, leaving a remainder of 692.
The next digit of our result is 6. 
Result so far: 56.0
If we take 5922 away from 6614, we end up with 692.
Fetch the next digit (6) from the dividend, attach it to 692 and continue: 6926 / 987

Let's proceed to step 6:
6926 divided by 987 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 567.0
The remainder is 17 after subtracting 6909 from 6926.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 987

Let's proceed to step 7:
When dividing 171 by 987, we get 0 with a remainder of 171.
Record the quotient 0 as the next digit in the result. 
Result so far: 5670.0
If we take 0 away from 171, we end up with 171.
Bring next digit (7) of the dividend behind the 171 and repeat the process: 1717 / 987

Step 8:
The number 987 fits into 1717 1 times, leaving a remainder of 730.
The number 1 becomes the next digit in our result. 
Result so far: 56701.0
If we take 987 away from 1717, we end up with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Step 9:
If we divide 7300 by 987, we get 7 and a remainder of 391.
The number 7 becomes the next digit in our result. 
Result so far: 56701.7
The remainder is 391 after subtracting 6909 from 7300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Step 10:
If we divide 3910 by 987, we get 3 and a remainder of 949.
The next digit of our result is 3. 
Result so far: 56701.73
Deduct 2961 from 3910 and we're left with 949.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9490, and continue the process.

Step 11:
987 goes into 9490 9 times with a remainder of 607.
Use 9 as the next digit of our solution. 
Result so far: 56701.739
If we subtract 8883 from 9490, we get 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Going ahead to step 12:
If we divide 6070 by 987, we get 6 and a remainder of 148.
Write down 6 as next digit of the result. 
Result so far: 56701.7396
The remainder is 148 after subtracting 5922 from 6070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 13:
987 goes into 1480 1 times with a remainder of 493.
Use 1 as the next digit of our solution. 
Result so far: 56701.73961
The remainder is 493 after subtracting 987 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Moving on to step 14:
987 goes into 4930 4 times with a remainder of 982.
Write down 4 as next digit of the result. 
Result so far: 56701.739614
Subtract 3948 from 4930 to get 982.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9820, and continue the process.

Let's proceed to step 15:
The number 987 fits into 9820 9 times, leaving a remainder of 937.
The number 9 becomes the next digit in our result. 
Result so far: 56701.7396149
Deduct 8883 from 9820 and we're left with 937.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9370, and continue the process.

Moving on to step 16:
The number 987 fits into 9370 9 times, leaving a remainder of 487.
The next digit of our result is 9. 
Result so far: 56701.73961499
Deduct 8883 from 9370 and we're left with 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

After the division, we end up with 56701.73961499 and a remainder of 4.87e-07.
