We look at the division of 93624891 by 756 
The aim is to understand the frequency of 756 in 93624891.

Moving on to step 1:
When dividing 9 by 756, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 756

Let's proceed to step 2:
If we divide 93 by 756, we get 0 and a remainder of 93.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 93 to get 93.
Append the next digit (6) from the dividend to 93 and continue with: 936 / 756

Going ahead to step 3:
The number 756 fits into 936 1 times, leaving a remainder of 180.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 756 from 936 leaves us with 180.
Take the next digit (2) from the dividend and append it to 180, then repeat: 1802 / 756

Step 4:
756 can be fit into 1802 2 times, resulting in a remainder of 290.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1512 from 1802 and we're left with 290.
Grab the next digit (4) from the dividend, add it to 290, then carry on: 2904 / 756

Step 5:
756 goes into 2904 3 times with a remainder of 636.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Subtracting 2268 from 2904 leaves us with 636.
Grab the next digit (8) from the dividend, add it to 636, then carry on: 6368 / 756

Let's proceed to step 6:
756 goes into 6368 8 times with a remainder of 320.
Put 8 as the next digit of the answer. 
Result so far: 1238.0
If we subtract 6048 from 6368, we get 320.
Take the next digit (9) from the dividend and append it to 320, then repeat: 3209 / 756

Going ahead to step 7:
756 goes into 3209 4 times with a remainder of 185.
Record the quotient 4 as the next digit in the result. 
Result so far: 12384.0
Deduct 3024 from 3209 and we're left with 185.
Bring next digit (1) of the dividend behind the 185 and repeat the process: 1851 / 756

On to step 8:
756 goes into 1851 2 times with a remainder of 339.
Put 2 as the next digit of the answer. 
Result so far: 123842.0
If we subtract 1512 from 1851, we get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Going ahead to step 9:
3390 divided by 756 is 4 with a remainder of 366.
Use 4 as the next digit of our solution. 
Result so far: 123842.4
If we subtract 3024 from 3390, we get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Moving on to step 10:
756 can be fit into 3660 4 times, resulting in a remainder of 636.
Put 4 as the next digit of the answer. 
Result so far: 123842.44
Subtract 3024 from 3660 to get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

The quotient of the division is 123842.44, and the remainder is 0.636.
