We're dividing 20090450 by 627 
The aim is to understand the frequency of 627 in 20090450.

On to step 1:
627 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 627

On to step 2:
627 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 627

Moving on to step 3:
When dividing 200 by 627, we get 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 200, we get 200.
Take the next digit (9) from the dividend and append it to 200, then repeat: 2009 / 627

Moving on to step 4:
627 goes into 2009 3 times with a remainder of 128.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 1881 from 2009 and we're left with 128.
Include the next digit (0) from the dividend after 128, then repeat: 1280 / 627

Step 5:
1280 divided by 627 is 2 with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 32.0
The remainder is 26 after subtracting 1254 from 1280.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 627

Moving on to step 6:
627 can be fit into 264 0 times, resulting in a remainder of 264.
Put 0 as the next digit of the answer. 
Result so far: 320.0
Subtract 0 from 264 to get 264.
Append the next digit (5) from the dividend to 264 and continue with: 2645 / 627

Going ahead to step 7:
627 can be fit into 2645 4 times, resulting in a remainder of 137.
Record the quotient 4 as the next digit in the result. 
Result so far: 3204.0
Subtracting 2508 from 2645 leaves us with 137.
Take the next digit (0) from the dividend and append it to 137, then repeat: 1370 / 627

Step 8:
If we divide 1370 by 627, we get 2 and a remainder of 116.
Put 2 as the next digit of the answer. 
Result so far: 32042.0
If we subtract 1254 from 1370, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 9:
1160 divided by 627 is 1 with a remainder of 533.
Record the quotient 1 as the next digit in the result. 
Result so far: 32042.1
Deduct 627 from 1160 and we're left with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Going ahead to step 10:
If we divide 5330 by 627, we get 8 and a remainder of 314.
Record the quotient 8 as the next digit in the result. 
Result so far: 32042.18
If we subtract 5016 from 5330, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 11:
627 goes into 3140 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 32042.185
If we subtract 3135 from 3140, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
When dividing 50 by 627, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 32042.185
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
627 goes into 500 0 times with a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 32042.185
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final result is 32042.185 with a remainder of 0.0005.
