43355597 ÷ 628 
The aim is to understand the frequency of 628 in 43355597.

Step 1:
4 divided by 628 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 628

Going ahead to step 2:
43 divided by 628 is 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Include the next digit (3) from the dividend after 43, then repeat: 433 / 628

Moving on to step 3:
433 divided by 628 is 0 with a remainder of 433.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 433 after subtracting 0 from 433.
Fetch the next digit (5) from the dividend, attach it to 433 and continue: 4335 / 628

On to step 4:
The number 628 fits into 4335 6 times, leaving a remainder of 567.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 3768 from 4335 to get 567.
Bring next digit (5) of the dividend behind the 567 and repeat the process: 5675 / 628

On to step 5:
If we divide 5675 by 628, we get 9 and a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 69.0
If we take 5652 away from 5675, we end up with 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 628

Advancing to step 6:
628 can be fit into 235 0 times, resulting in a remainder of 235.
Use 0 as the next digit of our solution. 
Result so far: 690.0
If we subtract 0 from 235, we get 235.
Fetch the next digit (9) from the dividend, attach it to 235 and continue: 2359 / 628

Going ahead to step 7:
The number 628 fits into 2359 3 times, leaving a remainder of 475.
Write down 3 as next digit of the result. 
Result so far: 6903.0
If we subtract 1884 from 2359, we get 475.
Fetch the next digit (7) from the dividend, attach it to 475 and continue: 4757 / 628

Going ahead to step 8:
If we divide 4757 by 628, we get 7 and a remainder of 361.
Record the quotient 7 as the next digit in the result. 
Result so far: 69037.0
If we take 4396 away from 4757, we end up with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Step 9:
If we divide 3610 by 628, we get 5 and a remainder of 470.
The number 5 becomes the next digit in our result. 
Result so far: 69037.5
If we subtract 3140 from 3610, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 10:
628 goes into 4700 7 times with a remainder of 304.
The number 7 becomes the next digit in our result. 
Result so far: 69037.57
The remainder is 304 after subtracting 4396 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 11:
If we divide 3040 by 628, we get 4 and a remainder of 528.
Put 4 as the next digit of the answer. 
Result so far: 69037.574
If we take 2512 away from 3040, we end up 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.

Step 12:
628 goes into 5280 8 times with a remainder of 256.
Write down 8 as next digit of the result. 
Result so far: 69037.5748
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.

Let's proceed to step 13:
When dividing 2560 by 628, we get 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 69037.57484
Deduct 2512 from 2560 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 14:
When dividing 480 by 628, we get 0 with a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 69037.57484
Subtracting 0 from 480 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 15:
When dividing 4800 by 628, we get 7 with a remainder of 404.
The number 7 becomes the next digit in our result. 
Result so far: 69037.5748407
If we subtract 4396 from 4800, we get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 16:
If we divide 4040 by 628, we get 6 and a remainder of 272.
Put 6 as the next digit of the answer. 
Result so far: 69037.57484076
If we take 3768 away from 4040, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

The quotient of the division is 69037.57484076, and the remainder is 2.72e-07.
