We're dividing 602848 by 86 
The aim is to understand the frequency of 86 in 602848.

Step 1:
If we divide 6 by 86, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 86

Advancing to step 2:
The number 86 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 60 leaves us with 60.
Append the next digit (2) from the dividend to 60 and continue with: 602 / 86

Moving on to step 3:
602 divided by 86 is 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 0 after subtracting 602 from 602.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 86

Going ahead to step 4:
86 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 70.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 86

Going ahead to step 5:
The number 86 fits into 84 0 times, leaving a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 700.0
The remainder is 84 after subtracting 0 from 84.
Append the next digit (8) from the dividend to 84 and continue with: 848 / 86

On to step 6:
The number 86 fits into 848 9 times, leaving a remainder of 74.
Write down 9 as next digit of the result. 
Result so far: 7009.0
Deduct 774 from 848 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 7:
The number 86 fits into 740 8 times, leaving a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 7009.8
Subtracting 688 from 740 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 8:
The number 86 fits into 520 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 7009.86
Deduct 516 from 520 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
86 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 7009.86
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
400 divided by 86 is 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 7009.8604
If we subtract 344 from 400, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
86 can be fit into 560 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 7009.86046
The remainder is 44 after subtracting 516 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 12:
86 goes into 440 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 7009.860465
If we subtract 430 from 440, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
The number 86 fits into 100 1 times, leaving a remainder of 14.
The next digit of our result is 1. 
Result so far: 7009.8604651
If we take 86 away from 100, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
The number 86 fits into 140 1 times, leaving a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 7009.86046511
Deduct 86 from 140 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 7009.86046511, and the remainder is 5.4e-08.
