Let's divide 503862 by 86
The aim is to understand the frequency of 86 in 503862.

On to step 1:
If we divide 5 by 86, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 86

Going ahead to step 2:
50 divided by 86 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Bring next digit (3) of the dividend behind the 50 and repeat the process: 503 / 86

Advancing to step 3:
When dividing 503 by 86, we get 5 with a remainder of 73.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 430 away from 503, we end up with 73.
Include the next digit (8) from the dividend after 73, then repeat: 738 / 86

Going ahead to step 4:
The number 86 fits into 738 8 times, leaving a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 58.0
If we take 688 away from 738, we end up with 50.
Take the next digit (6) from the dividend and append it to 50, then repeat: 506 / 86

Moving on to step 5:
The number 86 fits into 506 5 times, leaving a remainder of 76.
Put 5 as the next digit of the answer. 
Result so far: 585.0
If we subtract 430 from 506, we get 76.
Take the next digit (2) from the dividend and append it to 76, then repeat: 762 / 86

On to step 6:
762 divided by 86 is 8 with a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 5858.0
Subtracting 688 from 762 leaves us 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:
740 divided by 86 is 8 with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 5858.8
If we take 688 away from 740, we end up 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.

Moving on to step 8:
86 can be fit into 520 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 5858.86
Subtracting 516 from 520 leaves us 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:
If we divide 40 by 86, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 5858.86
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
The number 86 fits into 400 4 times, leaving a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 5858.8604
Subtracting 344 from 400 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
560 divided by 86 is 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 5858.86046
Subtract 516 from 560 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
When dividing 440 by 86, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 5858.860465
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.

Going ahead to step 13:
100 divided by 86 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 5858.8604651
If we subtract 86 from 100, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 14:
When dividing 140 by 86, we get 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 5858.86046511
If we take 86 away from 140, we end up 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.

After the division, we end up with 5858.86046511 and a remainder of 5.4e-08.
