55649609 ÷ 860 
The aim is to understand the frequency of 860 in 55649609.

Moving on to step 1:
If we divide 5 by 860, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 860

Going ahead to step 2:
860 can be fit into 55 0 times, resulting in a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Grab the next digit (6) from the dividend, add it to 55, then carry on: 556 / 860

Going ahead to step 3:
If we divide 556 by 860, we get 0 and a remainder of 556.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 556, we end up with 556.
Include the next digit (4) from the dividend after 556, then repeat: 5564 / 860

Let's proceed to step 4:
860 goes into 5564 6 times with a remainder of 404.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 5160 from 5564 to get 404.
Take the next digit (9) from the dividend and append it to 404, then repeat: 4049 / 860

Step 5:
The number 860 fits into 4049 4 times, leaving a remainder of 609.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
If we subtract 3440 from 4049, we get 609.
Take the next digit (6) from the dividend and append it to 609, then repeat: 6096 / 860

Advancing to step 6:
When dividing 6096 by 860, we get 7 with a remainder of 76.
Put 7 as the next digit of the answer. 
Result so far: 647.0
Deduct 6020 from 6096 and we're left with 76.
Fetch the next digit (0) from the dividend, attach it to 76 and continue: 760 / 860

On to step 7:
860 goes into 760 0 times with a remainder of 760.
The next digit of our result is 0. 
Result so far: 6470.0
If we take 0 away from 760, we end up with 760.
Append the next digit (9) from the dividend to 760 and continue with: 7609 / 860

Going ahead to step 8:
860 can be fit into 7609 8 times, resulting in a remainder of 729.
Use 8 as the next digit of our solution. 
Result so far: 64708.0
Subtract 6880 from 7609 to get 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

Going ahead to step 9:
7290 divided by 860 is 8 with a remainder of 410.
The next digit of our result is 8. 
Result so far: 64708.8
Subtract 6880 from 7290 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 10:
860 can be fit into 4100 4 times, resulting in a remainder of 660.
Use 4 as the next digit of our solution. 
Result so far: 64708.84
If we subtract 3440 from 4100, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 11:
When dividing 6600 by 860, we get 7 with a remainder of 580.
The number 7 becomes the next digit in our result. 
Result so far: 64708.847
Subtract 6020 from 6600 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

On to step 12:
5800 divided by 860 is 6 with a remainder of 640.
The next digit of our result is 6. 
Result so far: 64708.8476
Subtracting 5160 from 5800 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 13:
6400 divided by 860 is 7 with a remainder of 380.
Use 7 as the next digit of our solution. 
Result so far: 64708.84767
Subtracting 6020 from 6400 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 14:
If we divide 3800 by 860, we get 4 and a remainder of 360.
Use 4 as the next digit of our solution. 
Result so far: 64708.847674
If we subtract 3440 from 3800, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 15:
If we divide 3600 by 860, we get 4 and a remainder of 160.
Use 4 as the next digit of our solution. 
Result so far: 64708.8476744
Subtract 3440 from 3600 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Our division results in 64708.8476744 with a remaining 1.6e-06.
