589625 divided by 86 
The aim is to understand the frequency of 86 in 589625.

Step 1:
5 divided by 86 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 86

On to step 2:
The number 86 fits into 58 0 times, leaving a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Bring next digit (9) of the dividend behind the 58 and repeat the process: 589 / 86

Step 3:
When dividing 589 by 86, we get 6 with a remainder of 73.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 516 from 589 leaves us with 73.
Grab the next digit (6) from the dividend, add it to 73, then carry on: 736 / 86

Advancing to step 4:
86 goes into 736 8 times with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 68.0
If we take 688 away from 736, we end up with 48.
Append the next digit (2) from the dividend to 48 and continue with: 482 / 86

On to step 5:
86 can be fit into 482 5 times, resulting in a remainder of 52.
Use 5 as the next digit of our solution. 
Result so far: 685.0
The remainder is 52 after subtracting 430 from 482.
Take the next digit (5) from the dividend and append it to 52, then repeat: 525 / 86

Let's proceed to step 6:
525 divided by 86 is 6 with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 6856.0
Deduct 516 from 525 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
The number 86 fits into 90 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 6856.1
Subtract 86 from 90 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
86 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 6856.1
Subtracting 0 from 40 leaves us 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.

On to step 9:
86 goes into 400 4 times with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 6856.104
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.

Step 10:
560 divided by 86 is 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 6856.1046
If we subtract 516 from 560, we 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 11:
The number 86 fits into 440 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 6856.10465
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.

On to step 12:
86 goes into 100 1 times with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 6856.104651
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.

Advancing to step 13:
86 goes into 140 1 times with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 6856.1046511
Subtract 86 from 140 to get 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 final result is 6856.1046511 with a remainder of 5.4e-07.
