18259197 divided by 860 
The aim is to understand the frequency of 860 in 18259197.

Advancing to step 1:
The number 860 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 860

Advancing to step 2:
860 goes into 18 0 times with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 860

Going ahead to step 3:
860 goes into 182 0 times with a remainder of 182.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 182, we get 182.
Include the next digit (5) from the dividend after 182, then repeat: 1825 / 860

Moving on to step 4:
The number 860 fits into 1825 2 times, leaving a remainder of 105.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1720 from 1825 and we're left with 105.
Take the next digit (9) from the dividend and append it to 105, then repeat: 1059 / 860

On to step 5:
1059 divided by 860 is 1 with a remainder of 199.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 860 from 1059 and we're left with 199.
Take the next digit (1) from the dividend and append it to 199, then repeat: 1991 / 860

Advancing to step 6:
The number 860 fits into 1991 2 times, leaving a remainder of 271.
Put 2 as the next digit of the answer. 
Result so far: 212.0
Subtracting 1720 from 1991 leaves us with 271.
Bring next digit (9) of the dividend behind the 271 and repeat the process: 2719 / 860

Advancing to step 7:
The number 860 fits into 2719 3 times, leaving a remainder of 139.
Write down 3 as next digit of the result. 
Result so far: 2123.0
Subtract 2580 from 2719 to get 139.
Grab the next digit (7) from the dividend, add it to 139, then carry on: 1397 / 860

On to step 8:
The number 860 fits into 1397 1 times, leaving a remainder of 537.
Write down 1 as next digit of the result. 
Result so far: 21231.0
If we take 860 away from 1397, we end up with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Moving on to step 9:
860 can be fit into 5370 6 times, resulting in a remainder of 210.
Put 6 as the next digit of the answer. 
Result so far: 21231.6
Subtracting 5160 from 5370 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 10:
When dividing 2100 by 860, we get 2 with a remainder of 380.
Write down 2 as next digit of the result. 
Result so far: 21231.62
If we subtract 1720 from 2100, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 11:
860 can be fit into 3800 4 times, resulting in a remainder of 360.
Use 4 as the next digit of our solution. 
Result so far: 21231.624
The remainder is 360 after subtracting 3440 from 3800.
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 12:
860 goes into 3600 4 times with a remainder of 160.
Record the quotient 4 as the next digit in the result. 
Result so far: 21231.6244
If we take 3440 away from 3600, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The quotient of the division is 21231.6244, and the remainder is 0.0016.
