87851556 ÷ 622 
The aim is to understand the frequency of 622 in 87851556.

On to step 1:
The number 622 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 622

Step 2:
The number 622 fits into 87 0 times, leaving a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Bring next digit (8) of the dividend behind the 87 and repeat the process: 878 / 622

Let's proceed to step 3:
If we divide 878 by 622, we get 1 and a remainder of 256.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 622 away from 878, we end up with 256.
Fetch the next digit (5) from the dividend, attach it to 256 and continue: 2565 / 622

Going ahead to step 4:
When dividing 2565 by 622, we get 4 with a remainder of 77.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 2488 from 2565 leaves us with 77.
Bring next digit (1) of the dividend behind the 77 and repeat the process: 771 / 622

Moving on to step 5:
622 can be fit into 771 1 times, resulting in a remainder of 149.
Use 1 as the next digit of our solution. 
Result so far: 141.0
Subtract 622 from 771 to get 149.
Append the next digit (5) from the dividend to 149 and continue with: 1495 / 622

On to step 6:
When dividing 1495 by 622, we get 2 with a remainder of 251.
Write down 2 as next digit of the result. 
Result so far: 1412.0
Subtract 1244 from 1495 to get 251.
Take the next digit (5) from the dividend and append it to 251, then repeat: 2515 / 622

Moving on to step 7:
622 goes into 2515 4 times with a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 14124.0
Subtract 2488 from 2515 to get 27.
Take the next digit (6) from the dividend and append it to 27, then repeat: 276 / 622

Going ahead to step 8:
622 can be fit into 276 0 times, resulting in a remainder of 276.
Record the quotient 0 as the next digit in the result. 
Result so far: 141240.0
Subtract 0 from 276 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Going ahead to step 9:
622 can be fit into 2760 4 times, resulting in a remainder of 272.
The next digit of our result is 4. 
Result so far: 141240.4
If we subtract 2488 from 2760, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 10:
622 goes into 2720 4 times with a remainder of 232.
The number 4 becomes the next digit in our result. 
Result so far: 141240.44
If we subtract 2488 from 2720, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

After the division, we end up with 141240.44 and a remainder of 0.232.
