42489367 divided by 86 
The aim is to understand the frequency of 86 in 42489367.

Going ahead to step 1:
86 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 86

Going ahead to step 2:
42 divided by 86 is 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Grab the next digit (4) from the dividend, add it to 42, then carry on: 424 / 86

Moving on to step 3:
When dividing 424 by 86, we get 4 with a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 80 after subtracting 344 from 424.
Fetch the next digit (8) from the dividend, attach it to 80 and continue: 808 / 86

On to step 4:
When dividing 808 by 86, we get 9 with a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
Deduct 774 from 808 and we're left with 34.
Bring next digit (9) of the dividend behind the 34 and repeat the process: 349 / 86

Moving on to step 5:
86 can be fit into 349 4 times, resulting in a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 494.0
Subtracting 344 from 349 leaves us with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 86

Moving on to step 6:
When dividing 53 by 86, we get 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 4940.0
If we subtract 0 from 53, we get 53.
Include the next digit (6) from the dividend after 53, then repeat: 536 / 86

Advancing to step 7:
When dividing 536 by 86, we get 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 49406.0
Subtracting 516 from 536 leaves us with 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 86

On to step 8:
86 can be fit into 207 2 times, resulting in a remainder of 35.
The number 2 becomes the next digit in our result. 
Result so far: 494062.0
Subtract 172 from 207 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
86 goes into 350 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 494062.4
Subtract 344 from 350 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
86 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 494062.4
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
If we divide 600 by 86, we get 6 and a remainder of 84.
The next digit of our result is 6. 
Result so far: 494062.406
If we take 516 away from 600, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 12:
840 divided by 86 is 9 with a remainder of 66.
The next digit of our result is 9. 
Result so far: 494062.4069
The remainder is 66 after subtracting 774 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 13:
When dividing 660 by 86, we get 7 with a remainder of 58.
The next digit of our result is 7. 
Result so far: 494062.40697
If we take 602 away from 660, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 14:
580 divided by 86 is 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 494062.406976
Subtracting 516 from 580 leaves us 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 15:
86 can be fit into 640 7 times, resulting in a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 494062.4069767
Deduct 602 from 640 and we're left with 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 16:
The number 86 fits into 380 4 times, leaving a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 494062.40697674
Subtracting 344 from 380 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 494062.40697674 with a remaining 3.6e-08.
