469790 divided by 86 
The aim is to understand the frequency of 86 in 469790.

On to step 1:
86 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 86

Going ahead to step 2:
If we divide 46 by 86, we get 0 and a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 46, we get 46.
Include the next digit (9) from the dividend after 46, then repeat: 469 / 86

Going ahead to step 3:
86 can be fit into 469 5 times, resulting in a remainder of 39.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 430 from 469 and we're left with 39.
Grab the next digit (7) from the dividend, add it to 39, then carry on: 397 / 86

Going ahead to step 4:
397 divided by 86 is 4 with a remainder of 53.
Use 4 as the next digit of our solution. 
Result so far: 54.0
Subtracting 344 from 397 leaves us with 53.
Append the next digit (9) from the dividend to 53 and continue with: 539 / 86

Advancing to step 5:
539 divided by 86 is 6 with a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 546.0
If we subtract 516 from 539, we get 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 86

Moving on to step 6:
If we divide 230 by 86, we get 2 and a remainder of 58.
The next digit of our result is 2. 
Result so far: 5462.0
Subtract 172 from 230 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 7:
When dividing 580 by 86, we get 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 5462.6
If we take 516 away from 580, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 8:
The number 86 fits into 640 7 times, leaving a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 5462.67
Subtract 602 from 640 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 9:
If we divide 380 by 86, we get 4 and a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 5462.674
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
360 divided by 86 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 5462.6744
If we take 344 away from 360, we end up 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.

After the division, we end up with 5462.6744 and a remainder of 0.00016.
