We're dividing 75487700 by 672 
The aim is to understand the frequency of 672 in 75487700.

Advancing to step 1:
When dividing 7 by 672, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 672

Advancing to step 2:
672 can be fit into 75 0 times, resulting in a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Bring next digit (4) of the dividend behind the 75 and repeat the process: 754 / 672

Advancing to step 3:
When dividing 754 by 672, we get 1 with a remainder of 82.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 82 after subtracting 672 from 754.
Fetch the next digit (8) from the dividend, attach it to 82 and continue: 828 / 672

Moving on to step 4:
828 divided by 672 is 1 with a remainder of 156.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 156 after subtracting 672 from 828.
Take the next digit (7) from the dividend and append it to 156, then repeat: 1567 / 672

Going ahead to step 5:
672 can be fit into 1567 2 times, resulting in a remainder of 223.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
If we take 1344 away from 1567, we end up with 223.
Append the next digit (7) from the dividend to 223 and continue with: 2237 / 672

Moving on to step 6:
If we divide 2237 by 672, we get 3 and a remainder of 221.
Record the quotient 3 as the next digit in the result. 
Result so far: 1123.0
If we subtract 2016 from 2237, we get 221.
Append the next digit (0) from the dividend to 221 and continue with: 2210 / 672

Moving on to step 7:
When dividing 2210 by 672, we get 3 with a remainder of 194.
The number 3 becomes the next digit in our result. 
Result so far: 11233.0
Subtracting 2016 from 2210 leaves us with 194.
Include the next digit (0) from the dividend after 194, then repeat: 1940 / 672

On to step 8:
672 can be fit into 1940 2 times, resulting in a remainder of 596.
The number 2 becomes the next digit in our result. 
Result so far: 112332.0
Subtracting 1344 from 1940 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

On to step 9:
When dividing 5960 by 672, we get 8 with a remainder of 584.
The next digit of our result is 8. 
Result so far: 112332.8
Subtract 5376 from 5960 to get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Moving on to step 10:
The number 672 fits into 5840 8 times, leaving a remainder of 464.
The next digit of our result is 8. 
Result so far: 112332.88
The remainder is 464 after subtracting 5376 from 5840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

The quotient of the division is 112332.88, and the remainder is 0.464.
