We look at the division of 79428808 by 860 
The aim is to understand the frequency of 860 in 79428808.

Moving on to step 1:
When dividing 7 by 860, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 860

Advancing to step 2:
860 goes into 79 0 times with a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Bring next digit (4) of the dividend behind the 79 and repeat the process: 794 / 860

Going ahead to step 3:
The number 860 fits into 794 0 times, leaving a remainder of 794.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 794, we end up with 794.
Include the next digit (2) from the dividend after 794, then repeat: 7942 / 860

Advancing to step 4:
860 goes into 7942 9 times with a remainder of 202.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 7740 from 7942 leaves us with 202.
Fetch the next digit (8) from the dividend, attach it to 202 and continue: 2028 / 860

Step 5:
860 can be fit into 2028 2 times, resulting in a remainder of 308.
The next digit of our result is 2. 
Result so far: 92.0
Subtracting 1720 from 2028 leaves us with 308.
Grab the next digit (8) from the dividend, add it to 308, then carry on: 3088 / 860

Going ahead to step 6:
860 can be fit into 3088 3 times, resulting in a remainder of 508.
The next digit of our result is 3. 
Result so far: 923.0
Subtract 2580 from 3088 to get 508.
Bring next digit (0) of the dividend behind the 508 and repeat the process: 5080 / 860

On to step 7:
If we divide 5080 by 860, we get 5 and a remainder of 780.
The number 5 becomes the next digit in our result. 
Result so far: 9235.0
Subtracting 4300 from 5080 leaves us with 780.
Take the next digit (8) from the dividend and append it to 780, then repeat: 7808 / 860

On to step 8:
The number 860 fits into 7808 9 times, leaving a remainder of 68.
Record the quotient 9 as the next digit in the result. 
Result so far: 92359.0
Deduct 7740 from 7808 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
If we divide 680 by 860, we get 0 and a remainder of 680.
Use 0 as the next digit of our solution. 
Result so far: 92359.0
Subtracting 0 from 680 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 10:
The number 860 fits into 6800 7 times, leaving a remainder of 780.
Use 7 as the next digit of our solution. 
Result so far: 92359.07
Subtracting 6020 from 6800 leaves us with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Moving on to step 11:
860 goes into 7800 9 times with a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 92359.079
Subtract 7740 from 7800 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
860 can be fit into 600 0 times, resulting in a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 92359.079
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 13:
860 goes into 6000 6 times with a remainder of 840.
Record the quotient 6 as the next digit in the result. 
Result so far: 92359.07906
If we take 5160 away from 6000, we end up with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Step 14:
If we divide 8400 by 860, we get 9 and a remainder of 660.
The next digit of our result is 9. 
Result so far: 92359.079069
Subtract 7740 from 8400 to 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 15:
If we divide 6600 by 860, we get 7 and a remainder of 580.
The number 7 becomes the next digit in our result. 
Result so far: 92359.0790697
Subtracting 6020 from 6600 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 16:
5800 divided by 860 is 6 with a remainder of 640.
Put 6 as the next digit of the answer. 
Result so far: 92359.07906976
Deduct 5160 from 5800 and we're left 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.

The final result is 92359.07906976 with a remainder of 6.4e-07.
