We're dividing 863930 by 59 
The aim is to understand the frequency of 59 in 863930.

Step 1:
59 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 59

Going ahead to step 2:
59 goes into 86 1 times with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 59 from 86 and we're left with 27.
Include the next digit (3) from the dividend after 27, then repeat: 273 / 59

Let's proceed to step 3:
59 can be fit into 273 4 times, resulting in a remainder of 37.
The next digit of our result is 4. 
Result so far: 14.0
If we take 236 away from 273, we end up with 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 59

Step 4:
When dividing 379 by 59, we get 6 with a remainder of 25.
Use 6 as the next digit of our solution. 
Result so far: 146.0
If we take 354 away from 379, we end up with 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 59

Going ahead to step 5:
The number 59 fits into 253 4 times, leaving a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 1464.0
The remainder is 17 after subtracting 236 from 253.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 59

Going ahead to step 6:
When dividing 170 by 59, we get 2 with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 14642.0
The remainder is 52 after subtracting 118 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 7:
59 can be fit into 520 8 times, resulting in a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 14642.8
The remainder is 48 after subtracting 472 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 8:
The number 59 fits into 480 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 14642.88
Deduct 472 from 480 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 14642.88 with a remainder of 0.008.
