We're dividing 80930552 by 628 
The aim is to understand the frequency of 628 in 80930552.

On to step 1:
628 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 628

Step 2:
628 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Grab the next digit (9) from the dividend, add it to 80, then carry on: 809 / 628

Going ahead to step 3:
628 goes into 809 1 times with a remainder of 181.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 628 from 809, we get 181.
Bring next digit (3) of the dividend behind the 181 and repeat the process: 1813 / 628

Step 4:
628 goes into 1813 2 times with a remainder of 557.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 557 after subtracting 1256 from 1813.
Fetch the next digit (0) from the dividend, attach it to 557 and continue: 5570 / 628

Advancing to step 5:
When dividing 5570 by 628, we get 8 with a remainder of 546.
Put 8 as the next digit of the answer. 
Result so far: 128.0
If we take 5024 away from 5570, we end up with 546.
Fetch the next digit (5) from the dividend, attach it to 546 and continue: 5465 / 628

Going ahead to step 6:
When dividing 5465 by 628, we get 8 with a remainder of 441.
The number 8 becomes the next digit in our result. 
Result so far: 1288.0
The remainder is 441 after subtracting 5024 from 5465.
Take the next digit (5) from the dividend and append it to 441, then repeat: 4415 / 628

Going ahead to step 7:
When dividing 4415 by 628, we get 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 12887.0
If we subtract 4396 from 4415, we get 19.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 628

Advancing to step 8:
The number 628 fits into 192 0 times, leaving a remainder of 192.
Record the quotient 0 as the next digit in the result. 
Result so far: 128870.0
If we take 0 away from 192, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 9:
628 can be fit into 1920 3 times, resulting in a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 128870.3
Subtract 1884 from 1920 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
The number 628 fits into 360 0 times, leaving a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 128870.3
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 11:
When dividing 3600 by 628, we get 5 with a remainder of 460.
Put 5 as the next digit of the answer. 
Result so far: 128870.305
If we subtract 3140 from 3600, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 12:
When dividing 4600 by 628, we get 7 with a remainder of 204.
The number 7 becomes the next digit in our result. 
Result so far: 128870.3057
The remainder is 204 after subtracting 4396 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 13:
2040 divided by 628 is 3 with a remainder of 156.
Put 3 as the next digit of the answer. 
Result so far: 128870.30573
Subtracting 1884 from 2040 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 14:
628 can be fit into 1560 2 times, resulting in a remainder of 304.
Write down 2 as next digit of the result. 
Result so far: 128870.305732
The remainder is 304 after subtracting 1256 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 15:
The number 628 fits into 3040 4 times, leaving a remainder of 528.
Write down 4 as next digit of the result. 
Result so far: 128870.3057324
Subtracting 2512 from 3040 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Let's proceed to step 16:
5280 divided by 628 is 8 with a remainder of 256.
Write down 8 as next digit of the result. 
Result so far: 128870.30573248
If we take 5024 away from 5280, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Our division results in 128870.30573248 with a remaining 2.56e-07.
