We look at the division of 78632161 by 756 
The aim is to understand the frequency of 756 in 78632161.

On to step 1:
When dividing 7 by 756, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 756

On to step 2:
If we divide 78 by 756, we get 0 and a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Append the next digit (6) from the dividend to 78 and continue with: 786 / 756

Step 3:
When dividing 786 by 756, we get 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 756 from 786 leaves us with 30.
Fetch the next digit (3) from the dividend, attach it to 30 and continue: 303 / 756

Step 4:
303 divided by 756 is 0 with a remainder of 303.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 303, we get 303.
Fetch the next digit (2) from the dividend, attach it to 303 and continue: 3032 / 756

Step 5:
756 goes into 3032 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
If we take 3024 away from 3032, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 756

Moving on to step 6:
81 divided by 756 is 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 1040.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (6) from the dividend, attach it to 81 and continue: 816 / 756

On to step 7:
756 goes into 816 1 times with a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 10401.0
Subtracting 756 from 816 leaves us with 60.
Bring next digit (1) of the dividend behind the 60 and repeat the process: 601 / 756

On to step 8:
When dividing 601 by 756, we get 0 with a remainder of 601.
The number 0 becomes the next digit in our result. 
Result so far: 104010.0
If we take 0 away from 601, we end up with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Step 9:
If we divide 6010 by 756, we get 7 and a remainder of 718.
The next digit of our result is 7. 
Result so far: 104010.7
If we take 5292 away from 6010, we end up with 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Moving on to step 10:
756 can be fit into 7180 9 times, resulting in a remainder of 376.
Write down 9 as next digit of the result. 
Result so far: 104010.79
Deduct 6804 from 7180 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 11:
756 can be fit into 3760 4 times, resulting in a remainder of 736.
The number 4 becomes the next digit in our result. 
Result so far: 104010.794
If we subtract 3024 from 3760, we get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Let's proceed to step 12:
756 goes into 7360 9 times with a remainder of 556.
The next digit of our result is 9. 
Result so far: 104010.7949
Subtracting 6804 from 7360 leaves us with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Let's proceed to step 13:
The number 756 fits into 5560 7 times, leaving a remainder of 268.
The number 7 becomes the next digit in our result. 
Result so far: 104010.79497
Subtracting 5292 from 5560 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Step 14:
756 can be fit into 2680 3 times, resulting in a remainder of 412.
Record the quotient 3 as the next digit in the result. 
Result so far: 104010.794973
Subtract 2268 from 2680 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Going ahead to step 15:
756 goes into 4120 5 times with a remainder of 340.
Write down 5 as next digit of the result. 
Result so far: 104010.7949735
If we subtract 3780 from 4120, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 16:
756 goes into 3400 4 times with a remainder of 376.
Record the quotient 4 as the next digit in the result. 
Result so far: 104010.79497354
If we take 3024 away from 3400, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Our division results in 104010.79497354 with a remaining 3.76e-07.
