87146344 divided by 842 
The aim is to understand the frequency of 842 in 87146344.

Step 1:
8 divided by 842 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 842

Step 2:
When dividing 87 by 842, we get 0 with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Grab the next digit (1) from the dividend, add it to 87, then carry on: 871 / 842

Going ahead to step 3:
842 goes into 871 1 times with a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
If we take 842 away from 871, we end up with 29.
Grab the next digit (4) from the dividend, add it to 29, then carry on: 294 / 842

Let's proceed to step 4:
842 goes into 294 0 times with a remainder of 294.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 294, we end up with 294.
Append the next digit (6) from the dividend to 294 and continue with: 2946 / 842

Let's proceed to step 5:
842 goes into 2946 3 times with a remainder of 420.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
If we take 2526 away from 2946, we end up with 420.
Fetch the next digit (3) from the dividend, attach it to 420 and continue: 4203 / 842

Step 6:
842 goes into 4203 4 times with a remainder of 835.
Put 4 as the next digit of the answer. 
Result so far: 1034.0
If we subtract 3368 from 4203, we get 835.
Fetch the next digit (4) from the dividend, attach it to 835 and continue: 8354 / 842

Let's proceed to step 7:
The number 842 fits into 8354 9 times, leaving a remainder of 776.
The number 9 becomes the next digit in our result. 
Result so far: 10349.0
If we subtract 7578 from 8354, we get 776.
Bring next digit (4) of the dividend behind the 776 and repeat the process: 7764 / 842

On to step 8:
7764 divided by 842 is 9 with a remainder of 186.
Write down 9 as next digit of the result. 
Result so far: 103499.0
The remainder is 186 after subtracting 7578 from 7764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 9:
1860 divided by 842 is 2 with a remainder of 176.
Record the quotient 2 as the next digit in the result. 
Result so far: 103499.2
The remainder is 176 after subtracting 1684 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 10:
The number 842 fits into 1760 2 times, leaving a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 103499.22
The remainder is 76 after subtracting 1684 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 103499.22 and a remainder of 0.076.
