66774857 ÷ 628 
The aim is to understand the frequency of 628 in 66774857.

Let's proceed to step 1:
628 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 628

Going ahead to step 2:
66 divided by 628 is 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (7) from the dividend to 66 and continue with: 667 / 628

Moving on to step 3:
628 goes into 667 1 times with a remainder of 39.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 628 from 667 and we're left with 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 628

Going ahead to step 4:
If we divide 397 by 628, we get 0 and a remainder of 397.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 397, we get 397.
Grab the next digit (4) from the dividend, add it to 397, then carry on: 3974 / 628

On to step 5:
628 can be fit into 3974 6 times, resulting in a remainder of 206.
The next digit of our result is 6. 
Result so far: 106.0
If we take 3768 away from 3974, we end up with 206.
Bring next digit (8) of the dividend behind the 206 and repeat the process: 2068 / 628

Step 6:
The number 628 fits into 2068 3 times, leaving a remainder of 184.
The next digit of our result is 3. 
Result so far: 1063.0
If we take 1884 away from 2068, we end up with 184.
Take the next digit (5) from the dividend and append it to 184, then repeat: 1845 / 628

Let's proceed to step 7:
628 can be fit into 1845 2 times, resulting in a remainder of 589.
Write down 2 as next digit of the result. 
Result so far: 10632.0
If we take 1256 away from 1845, we end up with 589.
Bring next digit (7) of the dividend behind the 589 and repeat the process: 5897 / 628

Advancing to step 8:
628 goes into 5897 9 times with a remainder of 245.
Record the quotient 9 as the next digit in the result. 
Result so far: 106329.0
If we take 5652 away from 5897, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Moving on to step 9:
2450 divided by 628 is 3 with a remainder of 566.
Record the quotient 3 as the next digit in the result. 
Result so far: 106329.3
Deduct 1884 from 2450 and we're left with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Step 10:
When dividing 5660 by 628, we get 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 106329.39
The remainder is 8 after subtracting 5652 from 5660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
If we divide 80 by 628, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 106329.39
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
When dividing 800 by 628, we get 1 with a remainder of 172.
Write down 1 as next digit of the result. 
Result so far: 106329.3901
If we subtract 628 from 800, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 13:
628 can be fit into 1720 2 times, resulting in a remainder of 464.
Write down 2 as next digit of the result. 
Result so far: 106329.39012
Subtract 1256 from 1720 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Moving on to step 14:
If we divide 4640 by 628, we get 7 and a remainder of 244.
Record the quotient 7 as the next digit in the result. 
Result so far: 106329.390127
Subtracting 4396 from 4640 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 15:
If we divide 2440 by 628, we get 3 and a remainder of 556.
Write down 3 as next digit of the result. 
Result so far: 106329.3901273
The remainder is 556 after subtracting 1884 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

On to step 16:
If we divide 5560 by 628, we get 8 and a remainder of 536.
Use 8 as the next digit of our solution. 
Result so far: 106329.39012738
Deduct 5024 from 5560 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

The quotient of the division is 106329.39012738, and the remainder is 5.36e-07.
