Let's divide 56115520 by 748
The aim is to understand the frequency of 748 in 56115520.

Going ahead to step 1:
If we divide 5 by 748, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 748

On to step 2:
56 divided by 748 is 0 with a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Grab the next digit (1) from the dividend, add it to 56, then carry on: 561 / 748

Step 3:
If we divide 561 by 748, we get 0 and a remainder of 561.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 561 and we're left with 561.
Take the next digit (1) from the dividend and append it to 561, then repeat: 5611 / 748

Step 4:
When dividing 5611 by 748, we get 7 with a remainder of 375.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 375 after subtracting 5236 from 5611.
Append the next digit (5) from the dividend to 375 and continue with: 3755 / 748

Let's proceed to step 5:
3755 divided by 748 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 75.0
If we take 3740 away from 3755, we end up with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 748

Going ahead to step 6:
If we divide 155 by 748, we get 0 and a remainder of 155.
Put 0 as the next digit of the answer. 
Result so far: 750.0
Subtracting 0 from 155 leaves us with 155.
Include the next digit (2) from the dividend after 155, then repeat: 1552 / 748

Step 7:
748 can be fit into 1552 2 times, resulting in a remainder of 56.
The next digit of our result is 2. 
Result so far: 7502.0
Subtract 1496 from 1552 to get 56.
Append the next digit (0) from the dividend to 56 and continue with: 560 / 748

Going ahead to step 8:
748 goes into 560 0 times with a remainder of 560.
Put 0 as the next digit of the answer. 
Result so far: 75020.0
Subtracting 0 from 560 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 9:
748 goes into 5600 7 times with a remainder of 364.
Record the quotient 7 as the next digit in the result. 
Result so far: 75020.7
Deduct 5236 from 5600 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 10:
If we divide 3640 by 748, we get 4 and a remainder of 648.
The next digit of our result is 4. 
Result so far: 75020.74
The remainder is 648 after subtracting 2992 from 3640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

On to step 11:
When dividing 6480 by 748, we get 8 with a remainder of 496.
Put 8 as the next digit of the answer. 
Result so far: 75020.748
If we subtract 5984 from 6480, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 12:
748 goes into 4960 6 times with a remainder of 472.
Record the quotient 6 as the next digit in the result. 
Result so far: 75020.7486
If we take 4488 away from 4960, we end up with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Going ahead to step 13:
748 can be fit into 4720 6 times, resulting in a remainder of 232.
Put 6 as the next digit of the answer. 
Result so far: 75020.74866
If we subtract 4488 from 4720, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

The quotient of the division is 75020.74866, and the remainder is 0.000232.
