We look at the division of 494338 by 748 
The aim is to understand the frequency of 748 in 494338.

Let's proceed to step 1:
When dividing 4 by 748, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 748

Step 2:
748 can be fit into 49 0 times, resulting in a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Include the next digit (4) from the dividend after 49, then repeat: 494 / 748

Let's proceed to step 3:
748 can be fit into 494 0 times, resulting in a remainder of 494.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 494 leaves us with 494.
Grab the next digit (3) from the dividend, add it to 494, then carry on: 4943 / 748

Moving on to step 4:
When dividing 4943 by 748, we get 6 with a remainder of 455.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 455 after subtracting 4488 from 4943.
Fetch the next digit (3) from the dividend, attach it to 455 and continue: 4553 / 748

Advancing to step 5:
748 goes into 4553 6 times with a remainder of 65.
Write down 6 as next digit of the result. 
Result so far: 66.0
If we subtract 4488 from 4553, we get 65.
Include the next digit (8) from the dividend after 65, then repeat: 658 / 748

Moving on to step 6:
If we divide 658 by 748, we get 0 and a remainder of 658.
Write down 0 as next digit of the result. 
Result so far: 660.0
Subtract 0 from 658 to get 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Step 7:
If we divide 6580 by 748, we get 8 and a remainder of 596.
Put 8 as the next digit of the answer. 
Result so far: 660.8
If we subtract 5984 from 6580, we get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Let's proceed to step 8:
If we divide 5960 by 748, we get 7 and a remainder of 724.
Use 7 as the next digit of our solution. 
Result so far: 660.87
If we take 5236 away from 5960, we end up with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Let's proceed to step 9:
The number 748 fits into 7240 9 times, leaving a remainder of 508.
Record the quotient 9 as the next digit in the result. 
Result so far: 660.879
If we take 6732 away from 7240, we end up with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Advancing to step 10:
5080 divided by 748 is 6 with a remainder of 592.
The number 6 becomes the next digit in our result. 
Result so far: 660.8796
Deduct 4488 from 5080 and we're left with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Step 11:
748 can be fit into 5920 7 times, resulting in a remainder of 684.
The number 7 becomes the next digit in our result. 
Result so far: 660.87967
Subtracting 5236 from 5920 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.

Let's proceed to step 12:
When dividing 6840 by 748, we get 9 with a remainder of 108.
Record the quotient 9 as the next digit in the result. 
Result so far: 660.879679
The remainder is 108 after subtracting 6732 from 6840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 13:
The number 748 fits into 1080 1 times, leaving a remainder of 332.
Write down 1 as next digit of the result. 
Result so far: 660.8796791
Deduct 748 from 1080 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Let's proceed to step 14:
748 goes into 3320 4 times with a remainder of 328.
The number 4 becomes the next digit in our result. 
Result so far: 660.87967914
If we subtract 2992 from 3320, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

The quotient of the division is 660.87967914, and the remainder is 3.28e-07.
