We're dividing 724715 by 86 
The aim is to understand the frequency of 86 in 724715.

Advancing to step 1:
86 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 86

Step 2:
If we divide 72 by 86, we get 0 and a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Bring next digit (4) of the dividend behind the 72 and repeat the process: 724 / 86

On to step 3:
If we divide 724 by 86, we get 8 and a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 688 from 724, we get 36.
Fetch the next digit (7) from the dividend, attach it to 36 and continue: 367 / 86

On to step 4:
When dividing 367 by 86, we get 4 with a remainder of 23.
The next digit of our result is 4. 
Result so far: 84.0
Subtracting 344 from 367 leaves us with 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 86

Let's proceed to step 5:
If we divide 231 by 86, we get 2 and a remainder of 59.
Write down 2 as next digit of the result. 
Result so far: 842.0
The remainder is 59 after subtracting 172 from 231.
Take the next digit (5) from the dividend and append it to 59, then repeat: 595 / 86

Moving on to step 6:
86 can be fit into 595 6 times, resulting in a remainder of 79.
Write down 6 as next digit of the result. 
Result so far: 8426.0
Subtracting 516 from 595 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 7:
When dividing 790 by 86, we get 9 with a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 8426.9
Subtracting 774 from 790 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
The number 86 fits into 160 1 times, leaving a remainder of 74.
Put 1 as the next digit of the answer. 
Result so far: 8426.91
If we take 86 away from 160, we end up 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 9:
86 can be fit into 740 8 times, resulting in a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 8426.918
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.

Let's proceed to step 10:
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: 8426.9186
The remainder is 4 after subtracting 516 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
The number 86 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 8426.9186
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.

Let's proceed to step 12:
86 can be fit into 400 4 times, resulting in a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 8426.918604
If we take 344 away from 400, we end up 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.

Let's proceed to step 13:
86 goes into 560 6 times with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 8426.9186046
Deduct 516 from 560 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 14:
If we divide 440 by 86, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 8426.91860465
The remainder is 10 after subtracting 430 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 8426.91860465 and a remainder of 1e-08.
