74485861 ÷ 622 
The aim is to understand the frequency of 622 in 74485861.

Step 1:
622 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 622

Let's proceed to step 2:
622 can be fit into 74 0 times, resulting in a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Grab the next digit (4) from the dividend, add it to 74, then carry on: 744 / 622

On to step 3:
If we divide 744 by 622, we get 1 and a remainder of 122.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 622 from 744 to get 122.
Take the next digit (8) from the dividend and append it to 122, then repeat: 1228 / 622

Step 4:
1228 divided by 622 is 1 with a remainder of 606.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 622 from 1228 to get 606.
Fetch the next digit (5) from the dividend, attach it to 606 and continue: 6065 / 622

Step 5:
When dividing 6065 by 622, we get 9 with a remainder of 467.
Write down 9 as next digit of the result. 
Result so far: 119.0
If we subtract 5598 from 6065, we get 467.
Include the next digit (8) from the dividend after 467, then repeat: 4678 / 622

Let's proceed to step 6:
622 can be fit into 4678 7 times, resulting in a remainder of 324.
The next digit of our result is 7. 
Result so far: 1197.0
Subtracting 4354 from 4678 leaves us with 324.
Bring next digit (6) of the dividend behind the 324 and repeat the process: 3246 / 622

Advancing to step 7:
If we divide 3246 by 622, we get 5 and a remainder of 136.
The number 5 becomes the next digit in our result. 
Result so far: 11975.0
If we take 3110 away from 3246, we end up with 136.
Fetch the next digit (1) from the dividend, attach it to 136 and continue: 1361 / 622

Step 8:
If we divide 1361 by 622, we get 2 and a remainder of 117.
Use 2 as the next digit of our solution. 
Result so far: 119752.0
If we take 1244 away from 1361, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 9:
1170 divided by 622 is 1 with a remainder of 548.
Put 1 as the next digit of the answer. 
Result so far: 119752.1
The remainder is 548 after subtracting 622 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Step 10:
5480 divided by 622 is 8 with a remainder of 504.
Record the quotient 8 as the next digit in the result. 
Result so far: 119752.18
If we subtract 4976 from 5480, we get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Going ahead to step 11:
The number 622 fits into 5040 8 times, leaving a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 119752.188
If we subtract 4976 from 5040, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 119752.188, with a leftover of 0.0064.
