We look at the division of 73453701 by 622 
The aim is to understand the frequency of 622 in 73453701.

Going ahead to step 1:
If we divide 7 by 622, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 622

Step 2:
622 can be fit into 73 0 times, resulting in a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Grab the next digit (4) from the dividend, add it to 73, then carry on: 734 / 622

Moving on to step 3:
734 divided by 622 is 1 with a remainder of 112.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 622 away from 734, we end up with 112.
Take the next digit (5) from the dividend and append it to 112, then repeat: 1125 / 622

On to step 4:
622 goes into 1125 1 times with a remainder of 503.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 622 from 1125 and we're left with 503.
Include the next digit (3) from the dividend after 503, then repeat: 5033 / 622

Advancing to step 5:
The number 622 fits into 5033 8 times, leaving a remainder of 57.
Write down 8 as next digit of the result. 
Result so far: 118.0
Subtracting 4976 from 5033 leaves us with 57.
Include the next digit (7) from the dividend after 57, then repeat: 577 / 622

On to step 6:
If we divide 577 by 622, we get 0 and a remainder of 577.
The number 0 becomes the next digit in our result. 
Result so far: 1180.0
Deduct 0 from 577 and we're left with 577.
Take the next digit (0) from the dividend and append it to 577, then repeat: 5770 / 622

Moving on to step 7:
622 can be fit into 5770 9 times, resulting in a remainder of 172.
Write down 9 as next digit of the result. 
Result so far: 11809.0
Subtracting 5598 from 5770 leaves us with 172.
Grab the next digit (1) from the dividend, add it to 172, then carry on: 1721 / 622

Moving on to step 8:
When dividing 1721 by 622, we get 2 with a remainder of 477.
Use 2 as the next digit of our solution. 
Result so far: 118092.0
Subtracting 1244 from 1721 leaves us with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Let's proceed to step 9:
When dividing 4770 by 622, we get 7 with a remainder of 416.
Put 7 as the next digit of the answer. 
Result so far: 118092.7
If we take 4354 away from 4770, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 10:
The number 622 fits into 4160 6 times, leaving a remainder of 428.
Put 6 as the next digit of the answer. 
Result so far: 118092.76
If we take 3732 away from 4160, we end up with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

On to step 11:
If we divide 4280 by 622, we get 6 and a remainder of 548.
Use 6 as the next digit of our solution. 
Result so far: 118092.766
If we subtract 3732 from 4280, we get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

The final outcome is 118092.766, with a leftover of 0.0548.
