Let's divide 86213291 by 842
The aim is to understand the frequency of 842 in 86213291.

Moving on to step 1:
842 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 842

Going ahead to step 2:
If we divide 86 by 842, we get 0 and a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Include the next digit (2) from the dividend after 86, then repeat: 862 / 842

Step 3:
The number 842 fits into 862 1 times, leaving a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 842 away from 862, we end up with 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 842

Moving on to step 4:
When dividing 201 by 842, we get 0 with a remainder of 201.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 201 to get 201.
Bring next digit (3) of the dividend behind the 201 and repeat the process: 2013 / 842

Step 5:
2013 divided by 842 is 2 with a remainder of 329.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
If we subtract 1684 from 2013, we get 329.
Take the next digit (2) from the dividend and append it to 329, then repeat: 3292 / 842

Moving on to step 6:
842 can be fit into 3292 3 times, resulting in a remainder of 766.
Put 3 as the next digit of the answer. 
Result so far: 1023.0
Deduct 2526 from 3292 and we're left with 766.
Append the next digit (9) from the dividend to 766 and continue with: 7669 / 842

Step 7:
842 goes into 7669 9 times with a remainder of 91.
Use 9 as the next digit of our solution. 
Result so far: 10239.0
Deduct 7578 from 7669 and we're left with 91.
Append the next digit (1) from the dividend to 91 and continue with: 911 / 842

On to step 8:
911 divided by 842 is 1 with a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 102391.0
Subtract 842 from 911 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 9:
842 can be fit into 690 0 times, resulting in a remainder of 690.
Write down 0 as next digit of the result. 
Result so far: 102391.0
The remainder is 690 after subtracting 0 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Step 10:
When dividing 6900 by 842, we get 8 with a remainder of 164.
Write down 8 as next digit of the result. 
Result so far: 102391.08
Subtract 6736 from 6900 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 11:
If we divide 1640 by 842, we get 1 and a remainder of 798.
The number 1 becomes the next digit in our result. 
Result so far: 102391.081
Deduct 842 from 1640 and we're left with 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Step 12:
If we divide 7980 by 842, we get 9 and a remainder of 402.
The number 9 becomes the next digit in our result. 
Result so far: 102391.0819
If we subtract 7578 from 7980, we get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Going ahead to step 13:
If we divide 4020 by 842, we get 4 and a remainder of 652.
The next digit of our result is 4. 
Result so far: 102391.08194
The remainder is 652 after subtracting 3368 from 4020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Moving on to step 14:
The number 842 fits into 6520 7 times, leaving a remainder of 626.
Use 7 as the next digit of our solution. 
Result so far: 102391.081947
If we subtract 5894 from 6520, we get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Let's proceed to step 15:
842 can be fit into 6260 7 times, resulting in a remainder of 366.
Put 7 as the next digit of the answer. 
Result so far: 102391.0819477
Deduct 5894 from 6260 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Our division results in 102391.0819477 with a remaining 3.66e-06.
