Let's divide 412139 by 86
The aim is to understand the frequency of 86 in 412139.

Going ahead to step 1:
The number 86 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 86

On to step 2:
86 can be fit into 41 0 times, resulting in a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 86

Let's proceed to step 3:
86 can be fit into 412 4 times, resulting in a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 344 from 412 leaves us with 68.
Append the next digit (1) from the dividend to 68 and continue with: 681 / 86

On to step 4:
If we divide 681 by 86, we get 7 and a remainder of 79.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
If we take 602 away from 681, we end up with 79.
Bring next digit (3) of the dividend behind the 79 and repeat the process: 793 / 86

Step 5:
793 divided by 86 is 9 with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 479.0
If we take 774 away from 793, we end up with 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 86

Let's proceed to step 6:
If we divide 199 by 86, we get 2 and a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 4792.0
If we take 172 away from 199, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
270 divided by 86 is 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 4792.3
The remainder is 12 after subtracting 258 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
If we divide 120 by 86, we get 1 and a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 4792.31
If we take 86 away from 120, we end up 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.

Advancing to step 9:
86 can be fit into 340 3 times, resulting in a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 4792.313
Deduct 258 from 340 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 10:
820 divided by 86 is 9 with a remainder of 46.
The next digit of our result is 9. 
Result so far: 4792.3139
If we subtract 774 from 820, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
86 can be fit into 460 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 4792.31395
Subtracting 430 from 460 leaves us 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.

Advancing to step 12:
The number 86 fits into 300 3 times, leaving a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 4792.313953
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
If we divide 420 by 86, we get 4 and a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 4792.3139534
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.

On to step 14:
If we divide 760 by 86, we get 8 and a remainder of 72.
The next digit of our result is 8. 
Result so far: 4792.31395348
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 4792.31395348 with a remainder of 7.2e-08.
