922142 divided by 87 
The aim is to understand the frequency of 87 in 922142.

Let's proceed to step 1:
If we divide 9 by 87, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 87

On to step 2:
87 goes into 92 1 times with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 87 from 92 leaves us with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 87

Advancing to step 3:
52 divided by 87 is 0 with a remainder of 52.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 52 after subtracting 0 from 52.
Grab the next digit (1) from the dividend, add it to 52, then carry on: 521 / 87

Moving on to step 4:
87 can be fit into 521 5 times, resulting in a remainder of 86.
Use 5 as the next digit of our solution. 
Result so far: 105.0
Subtract 435 from 521 to get 86.
Bring next digit (4) of the dividend behind the 86 and repeat the process: 864 / 87

Going ahead to step 5:
87 goes into 864 9 times with a remainder of 81.
Put 9 as the next digit of the answer. 
Result so far: 1059.0
If we take 783 away from 864, we end up with 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 87

Going ahead to step 6:
The number 87 fits into 812 9 times, leaving a remainder of 29.
The next digit of our result is 9. 
Result so far: 10599.0
Subtract 783 from 812 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
When dividing 290 by 87, we get 3 with a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 10599.3
Subtracting 261 from 290 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 8:
290 divided by 87 is 3 with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 10599.33
Subtracting 261 from 290 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The quotient of the division is 10599.33, and the remainder is 0.029.
