We look at the division of 53818137 by 756 
The aim is to understand the frequency of 756 in 53818137.

Step 1:
5 divided by 756 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 756

Step 2:
If we divide 53 by 756, we get 0 and a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Bring next digit (8) of the dividend behind the 53 and repeat the process: 538 / 756

Advancing to step 3:
538 divided by 756 is 0 with a remainder of 538.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 538 to get 538.
Bring next digit (1) of the dividend behind the 538 and repeat the process: 5381 / 756

Moving on to step 4:
756 can be fit into 5381 7 times, resulting in a remainder of 89.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 89 after subtracting 5292 from 5381.
Fetch the next digit (8) from the dividend, attach it to 89 and continue: 898 / 756

On to step 5:
756 goes into 898 1 times with a remainder of 142.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
The remainder is 142 after subtracting 756 from 898.
Bring next digit (1) of the dividend behind the 142 and repeat the process: 1421 / 756

On to step 6:
If we divide 1421 by 756, we get 1 and a remainder of 665.
Write down 1 as next digit of the result. 
Result so far: 711.0
The remainder is 665 after subtracting 756 from 1421.
Bring next digit (3) of the dividend behind the 665 and repeat the process: 6653 / 756

On to step 7:
The number 756 fits into 6653 8 times, leaving a remainder of 605.
Write down 8 as next digit of the result. 
Result so far: 7118.0
Deduct 6048 from 6653 and we're left with 605.
Bring next digit (7) of the dividend behind the 605 and repeat the process: 6057 / 756

Step 8:
6057 divided by 756 is 8 with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 71188.0
The remainder is 9 after subtracting 6048 from 6057.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
90 divided by 756 is 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 71188.0
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
756 goes into 900 1 times with a remainder of 144.
Put 1 as the next digit of the answer. 
Result so far: 71188.01
If we subtract 756 from 900, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 11:
The number 756 fits into 1440 1 times, leaving a remainder of 684.
Write down 1 as next digit of the result. 
Result so far: 71188.011
Subtracting 756 from 1440 leaves us with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

The final outcome is 71188.011, with a leftover of 0.0684.
