2579712 ÷ 628 
The aim is to understand the frequency of 628 in 2579712.

On to step 1:
628 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 628

Moving on to step 2:
628 can be fit into 25 0 times, resulting in a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 628

Advancing to step 3:
When dividing 257 by 628, we get 0 with a remainder of 257.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 257, we get 257.
Include the next digit (9) from the dividend after 257, then repeat: 2579 / 628

Advancing to step 4:
628 can be fit into 2579 4 times, resulting in a remainder of 67.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 67 after subtracting 2512 from 2579.
Take the next digit (7) from the dividend and append it to 67, then repeat: 677 / 628

On to step 5:
628 can be fit into 677 1 times, resulting in a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 41.0
The remainder is 49 after subtracting 628 from 677.
Fetch the next digit (1) from the dividend, attach it to 49 and continue: 491 / 628

On to step 6:
The number 628 fits into 491 0 times, leaving a remainder of 491.
Record the quotient 0 as the next digit in the result. 
Result so far: 410.0
If we take 0 away from 491, we end up with 491.
Bring next digit (2) of the dividend behind the 491 and repeat the process: 4912 / 628

Advancing to step 7:
628 goes into 4912 7 times with a remainder of 516.
Write down 7 as next digit of the result. 
Result so far: 4107.0
If we subtract 4396 from 4912, we get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Let's proceed to step 8:
When dividing 5160 by 628, we get 8 with a remainder of 136.
Use 8 as the next digit of our solution. 
Result so far: 4107.8
Deduct 5024 from 5160 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 9:
If we divide 1360 by 628, we get 2 and a remainder of 104.
The number 2 becomes the next digit in our result. 
Result so far: 4107.82
Subtracting 1256 from 1360 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 10:
628 can be fit into 1040 1 times, resulting in a remainder of 412.
Put 1 as the next digit of the answer. 
Result so far: 4107.821
The remainder is 412 after subtracting 628 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Step 11:
When dividing 4120 by 628, we get 6 with a remainder of 352.
The next digit of our result is 6. 
Result so far: 4107.8216
The remainder is 352 after subtracting 3768 from 4120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 12:
628 can be fit into 3520 5 times, resulting in a remainder of 380.
The next digit of our result is 5. 
Result so far: 4107.82165
If we subtract 3140 from 3520, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 13:
The number 628 fits into 3800 6 times, leaving a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 4107.821656
If we subtract 3768 from 3800, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
320 divided by 628 is 0 with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 4107.821656
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 15:
When dividing 3200 by 628, we get 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 4107.82165605
Subtracting 3140 from 3200 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 4107.82165605, and the remainder is 6e-08.
