We look at the division of 58315979 by 863 
The aim is to understand the frequency of 863 in 58315979.

Moving on to step 1:
863 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 863

Step 2:
When dividing 58 by 863, we get 0 with a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Bring next digit (3) of the dividend behind the 58 and repeat the process: 583 / 863

Let's proceed to step 3:
The number 863 fits into 583 0 times, leaving a remainder of 583.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 583 leaves us with 583.
Fetch the next digit (1) from the dividend, attach it to 583 and continue: 5831 / 863

Advancing to step 4:
863 goes into 5831 6 times with a remainder of 653.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 5178 away from 5831, we end up with 653.
Grab the next digit (5) from the dividend, add it to 653, then carry on: 6535 / 863

Let's proceed to step 5:
863 can be fit into 6535 7 times, resulting in a remainder of 494.
Put 7 as the next digit of the answer. 
Result so far: 67.0
Subtract 6041 from 6535 to get 494.
Include the next digit (9) from the dividend after 494, then repeat: 4949 / 863

Step 6:
The number 863 fits into 4949 5 times, leaving a remainder of 634.
Use 5 as the next digit of our solution. 
Result so far: 675.0
Subtracting 4315 from 4949 leaves us with 634.
Include the next digit (7) from the dividend after 634, then repeat: 6347 / 863

Advancing to step 7:
6347 divided by 863 is 7 with a remainder of 306.
The number 7 becomes the next digit in our result. 
Result so far: 6757.0
If we subtract 6041 from 6347, we get 306.
Grab the next digit (9) from the dividend, add it to 306, then carry on: 3069 / 863

Step 8:
When dividing 3069 by 863, we get 3 with a remainder of 480.
Put 3 as the next digit of the answer. 
Result so far: 67573.0
If we subtract 2589 from 3069, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 9:
The number 863 fits into 4800 5 times, leaving a remainder of 485.
Put 5 as the next digit of the answer. 
Result so far: 67573.5
The remainder is 485 after subtracting 4315 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Step 10:
863 can be fit into 4850 5 times, resulting in a remainder of 535.
Write down 5 as next digit of the result. 
Result so far: 67573.55
Deduct 4315 from 4850 and we're left with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

The quotient of the division is 67573.55, and the remainder is 0.535.
