53627363 divided by 756 
The aim is to understand the frequency of 756 in 53627363.

Step 1:
5 divided by 756 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 756

On to step 2:
When dividing 53 by 756, we get 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Take the next digit (6) from the dividend and append it to 53, then repeat: 536 / 756

Step 3:
When dividing 536 by 756, we get 0 with a remainder of 536.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 536 leaves us with 536.
Append the next digit (2) from the dividend to 536 and continue with: 5362 / 756

Step 4:
If we divide 5362 by 756, we get 7 and a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 5292 from 5362, we get 70.
Append the next digit (7) from the dividend to 70 and continue with: 707 / 756

Moving on to step 5:
707 divided by 756 is 0 with a remainder of 707.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Subtract 0 from 707 to get 707.
Take the next digit (3) from the dividend and append it to 707, then repeat: 7073 / 756

Moving on to step 6:
The number 756 fits into 7073 9 times, leaving a remainder of 269.
Record the quotient 9 as the next digit in the result. 
Result so far: 709.0
Deduct 6804 from 7073 and we're left with 269.
Fetch the next digit (6) from the dividend, attach it to 269 and continue: 2696 / 756

Advancing to step 7:
2696 divided by 756 is 3 with a remainder of 428.
Write down 3 as next digit of the result. 
Result so far: 7093.0
Deduct 2268 from 2696 and we're left with 428.
Append the next digit (3) from the dividend to 428 and continue with: 4283 / 756

Let's proceed to step 8:
When dividing 4283 by 756, we get 5 with a remainder of 503.
Record the quotient 5 as the next digit in the result. 
Result so far: 70935.0
Subtracting 3780 from 4283 leaves us with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

On to step 9:
When dividing 5030 by 756, we get 6 with a remainder of 494.
The number 6 becomes the next digit in our result. 
Result so far: 70935.6
If we subtract 4536 from 5030, we get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Step 10:
756 can be fit into 4940 6 times, resulting in a remainder of 404.
Write down 6 as next digit of the result. 
Result so far: 70935.66
If we take 4536 away from 4940, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

After the division, we end up with 70935.66 and a remainder of 0.404.
