57243724 ÷ 623 
The aim is to understand the frequency of 623 in 57243724.

On to step 1:
When dividing 5 by 623, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 623

Advancing to step 2:
623 can be fit into 57 0 times, resulting in a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Append the next digit (2) from the dividend to 57 and continue with: 572 / 623

Let's proceed to step 3:
623 goes into 572 0 times with a remainder of 572.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 572 leaves us with 572.
Bring next digit (4) of the dividend behind the 572 and repeat the process: 5724 / 623

Advancing to step 4:
If we divide 5724 by 623, we get 9 and a remainder of 117.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 5607 from 5724 to get 117.
Fetch the next digit (3) from the dividend, attach it to 117 and continue: 1173 / 623

Advancing to step 5:
1173 divided by 623 is 1 with a remainder of 550.
Write down 1 as next digit of the result. 
Result so far: 91.0
The remainder is 550 after subtracting 623 from 1173.
Grab the next digit (7) from the dividend, add it to 550, then carry on: 5507 / 623

Let's proceed to step 6:
When dividing 5507 by 623, we get 8 with a remainder of 523.
Write down 8 as next digit of the result. 
Result so far: 918.0
If we subtract 4984 from 5507, we get 523.
Fetch the next digit (2) from the dividend, attach it to 523 and continue: 5232 / 623

On to step 7:
When dividing 5232 by 623, we get 8 with a remainder of 248.
Use 8 as the next digit of our solution. 
Result so far: 9188.0
Subtracting 4984 from 5232 leaves us with 248.
Append the next digit (4) from the dividend to 248 and continue with: 2484 / 623

Moving on to step 8:
623 can be fit into 2484 3 times, resulting in a remainder of 615.
The next digit of our result is 3. 
Result so far: 91883.0
Subtracting 1869 from 2484 leaves us with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Let's proceed to step 9:
If we divide 6150 by 623, we get 9 and a remainder of 543.
Put 9 as the next digit of the answer. 
Result so far: 91883.9
If we take 5607 away from 6150, we end up with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

On to step 10:
623 goes into 5430 8 times with a remainder of 446.
Write down 8 as next digit of the result. 
Result so far: 91883.98
Deduct 4984 from 5430 and we're left with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Advancing to step 11:
When dividing 4460 by 623, we get 7 with a remainder of 99.
The next digit of our result is 7. 
Result so far: 91883.987
Subtract 4361 from 4460 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 12:
623 goes into 990 1 times with a remainder of 367.
The number 1 becomes the next digit in our result. 
Result so far: 91883.9871
If we subtract 623 from 990, we get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Step 13:
When dividing 3670 by 623, we get 5 with a remainder of 555.
Use 5 as the next digit of our solution. 
Result so far: 91883.98715
Subtracting 3115 from 3670 leaves us with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Moving on to step 14:
The number 623 fits into 5550 8 times, leaving a remainder of 566.
The next digit of our result is 8. 
Result so far: 91883.987158
The remainder is 566 after subtracting 4984 from 5550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Moving on to step 15:
623 goes into 5660 9 times with a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 91883.9871589
Subtract 5607 from 5660 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 16:
623 goes into 530 0 times with a remainder of 530.
The number 0 becomes the next digit in our result. 
Result so far: 91883.9871589
If we take 0 away from 530, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

In conclusion, the division gives 91883.9871589 with a balance of 5.3e-07.
