We're dividing 651849 by 86 
The aim is to understand the frequency of 86 in 651849.

Going ahead to step 1:
The number 86 fits into 6 0 times, leaving 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.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 86

Advancing to step 2:
65 divided by 86 is 0 with a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Take the next digit (1) from the dividend and append it to 65, then repeat: 651 / 86

Advancing to step 3:
86 goes into 651 7 times with a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 602 from 651 and we're left with 49.
Append the next digit (8) from the dividend to 49 and continue with: 498 / 86

Moving on to step 4:
When dividing 498 by 86, we get 5 with a remainder of 68.
The next digit of our result is 5. 
Result so far: 75.0
If we subtract 430 from 498, we get 68.
Grab the next digit (4) from the dividend, add it to 68, then carry on: 684 / 86

Moving on to step 5:
86 can be fit into 684 7 times, resulting in a remainder of 82.
Use 7 as the next digit of our solution. 
Result so far: 757.0
Deduct 602 from 684 and we're left with 82.
Include the next digit (9) from the dividend after 82, then repeat: 829 / 86

Moving on to step 6:
The number 86 fits into 829 9 times, leaving a remainder of 55.
Record the quotient 9 as the next digit in the result. 
Result so far: 7579.0
The remainder is 55 after subtracting 774 from 829.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 7:
86 goes into 550 6 times with a remainder of 34.
The next digit of our result is 6. 
Result so far: 7579.6
Subtracting 516 from 550 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
If we divide 340 by 86, we get 3 and a remainder of 82.
The number 3 becomes the next digit in our result. 
Result so far: 7579.63
Subtract 258 from 340 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 9:
The number 86 fits into 820 9 times, leaving a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 7579.639
Deduct 774 from 820 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 10:
When dividing 460 by 86, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 7579.6395
If we take 430 away from 460, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
If we divide 300 by 86, we get 3 and a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 7579.63953
Subtracting 258 from 300 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 12:
86 can be fit into 420 4 times, resulting in a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 7579.639534
Deduct 344 from 420 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 13:
When dividing 760 by 86, we get 8 with a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 7579.6395348
Deduct 688 from 760 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 14:
The number 86 fits into 720 8 times, leaving a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 7579.63953488
If we take 688 away from 720, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 7579.63953488 and a remainder of 3.2e-08.
