We look at the division of 80673984 by 757 
The aim is to understand the frequency of 757 in 80673984.

Let's proceed to step 1:
If we divide 8 by 757, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 757

Moving on to step 2:
The number 757 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Include the next digit (6) from the dividend after 80, then repeat: 806 / 757

Going ahead to step 3:
The number 757 fits into 806 1 times, leaving a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 49 after subtracting 757 from 806.
Append the next digit (7) from the dividend to 49 and continue with: 497 / 757

Going ahead to step 4:
757 can be fit into 497 0 times, resulting in a remainder of 497.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 497 after subtracting 0 from 497.
Bring next digit (3) of the dividend behind the 497 and repeat the process: 4973 / 757

Moving on to step 5:
If we divide 4973 by 757, we get 6 and a remainder of 431.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
Subtract 4542 from 4973 to get 431.
Bring next digit (9) of the dividend behind the 431 and repeat the process: 4319 / 757

Moving on to step 6:
If we divide 4319 by 757, we get 5 and a remainder of 534.
Use 5 as the next digit of our solution. 
Result so far: 1065.0
Deduct 3785 from 4319 and we're left with 534.
Bring next digit (8) of the dividend behind the 534 and repeat the process: 5348 / 757

Moving on to step 7:
5348 divided by 757 is 7 with a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 10657.0
The remainder is 49 after subtracting 5299 from 5348.
Take the next digit (4) from the dividend and append it to 49, then repeat: 494 / 757

Going ahead to step 8:
The number 757 fits into 494 0 times, leaving a remainder of 494.
Use 0 as the next digit of our solution. 
Result so far: 106570.0
If we take 0 away from 494, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Let's proceed to step 9:
757 goes into 4940 6 times with a remainder of 398.
The next digit of our result is 6. 
Result so far: 106570.6
Subtracting 4542 from 4940 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Going ahead to step 10:
If we divide 3980 by 757, we get 5 and a remainder of 195.
Use 5 as the next digit of our solution. 
Result so far: 106570.65
Subtracting 3785 from 3980 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 11:
757 can be fit into 1950 2 times, resulting in a remainder of 436.
Use 2 as the next digit of our solution. 
Result so far: 106570.652
Subtract 1514 from 1950 to get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Moving on to step 12:
When dividing 4360 by 757, we get 5 with a remainder of 575.
The next digit of our result is 5. 
Result so far: 106570.6525
If we subtract 3785 from 4360, we get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Let's proceed to step 13:
5750 divided by 757 is 7 with a remainder of 451.
The next digit of our result is 7. 
Result so far: 106570.65257
Subtracting 5299 from 5750 leaves us with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

On to step 14:
757 can be fit into 4510 5 times, resulting in a remainder of 725.
Put 5 as the next digit of the answer. 
Result so far: 106570.652575
Deduct 3785 from 4510 and we're left with 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Advancing to step 15:
If we divide 7250 by 757, we get 9 and a remainder of 437.
The number 9 becomes the next digit in our result. 
Result so far: 106570.6525759
Subtract 6813 from 7250 to get 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

On to step 16:
757 can be fit into 4370 5 times, resulting in a remainder of 585.
The next digit of our result is 5. 
Result so far: 106570.65257595
The remainder is 585 after subtracting 3785 from 4370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

The quotient of the division is 106570.65257595, and the remainder is 5.85e-07.
