54978152 divided by 757 
The aim is to understand the frequency of 757 in 54978152.

On to step 1:
If we divide 5 by 757, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 757

Step 2:
The number 757 fits into 54 0 times, leaving a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Take the next digit (9) from the dividend and append it to 54, then repeat: 549 / 757

Step 3:
When dividing 549 by 757, we get 0 with a remainder of 549.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 549, we end up with 549.
Append the next digit (7) from the dividend to 549 and continue with: 5497 / 757

Step 4:
5497 divided by 757 is 7 with a remainder of 198.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 5299 from 5497 to get 198.
Take the next digit (8) from the dividend and append it to 198, then repeat: 1988 / 757

Going ahead to step 5:
757 goes into 1988 2 times with a remainder of 474.
Put 2 as the next digit of the answer. 
Result so far: 72.0
The remainder is 474 after subtracting 1514 from 1988.
Append the next digit (1) from the dividend to 474 and continue with: 4741 / 757

Let's proceed to step 6:
4741 divided by 757 is 6 with a remainder of 199.
The number 6 becomes the next digit in our result. 
Result so far: 726.0
Subtracting 4542 from 4741 leaves us with 199.
Fetch the next digit (5) from the dividend, attach it to 199 and continue: 1995 / 757

Step 7:
757 goes into 1995 2 times with a remainder of 481.
The number 2 becomes the next digit in our result. 
Result so far: 7262.0
Deduct 1514 from 1995 and we're left with 481.
Include the next digit (2) from the dividend after 481, then repeat: 4812 / 757

Let's proceed to step 8:
If we divide 4812 by 757, we get 6 and a remainder of 270.
Put 6 as the next digit of the answer. 
Result so far: 72626.0
Subtracting 4542 from 4812 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 9:
The number 757 fits into 2700 3 times, leaving a remainder of 429.
The next digit of our result is 3. 
Result so far: 72626.3
If we take 2271 away from 2700, we end up with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

On to step 10:
757 goes into 4290 5 times with a remainder of 505.
Put 5 as the next digit of the answer. 
Result so far: 72626.35
If we subtract 3785 from 4290, we get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Let's proceed to step 11:
757 goes into 5050 6 times with a remainder of 508.
The next digit of our result is 6. 
Result so far: 72626.356
Subtract 4542 from 5050 to get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Advancing to step 12:
If we divide 5080 by 757, we get 6 and a remainder of 538.
Put 6 as the next digit of the answer. 
Result so far: 72626.3566
If we subtract 4542 from 5080, we get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

The quotient of the division is 72626.3566, and the remainder is 0.00538.
