We look at the division of 73651874 by 733 
The aim is to understand the frequency of 733 in 73651874.

On to step 1:
When dividing 7 by 733, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 733

Going ahead to step 2:
The number 733 fits into 73 0 times, leaving a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Bring next digit (6) of the dividend behind the 73 and repeat the process: 736 / 733

Step 3:
733 can be fit into 736 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 733 away from 736, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 733

Going ahead to step 4:
733 goes into 35 0 times with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 35 and we're left with 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 733

Moving on to step 5:
733 goes into 351 0 times with a remainder of 351.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Deduct 0 from 351 and we're left with 351.
Grab the next digit (8) from the dividend, add it to 351, then carry on: 3518 / 733

Advancing to step 6:
733 goes into 3518 4 times with a remainder of 586.
The number 4 becomes the next digit in our result. 
Result so far: 1004.0
Subtract 2932 from 3518 to get 586.
Take the next digit (7) from the dividend and append it to 586, then repeat: 5867 / 733

Step 7:
5867 divided by 733 is 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 10048.0
Subtracting 5864 from 5867 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 733

Step 8:
34 divided by 733 is 0 with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 100480.0
Subtracting 0 from 34 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
733 can be fit into 340 0 times, resulting in a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 100480.0
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 10:
733 goes into 3400 4 times with a remainder of 468.
Record the quotient 4 as the next digit in the result. 
Result so far: 100480.04
Subtracting 2932 from 3400 leaves us with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 11:
If we divide 4680 by 733, we get 6 and a remainder of 282.
Write down 6 as next digit of the result. 
Result so far: 100480.046
Subtracting 4398 from 4680 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 12:
733 can be fit into 2820 3 times, resulting in a remainder of 621.
Put 3 as the next digit of the answer. 
Result so far: 100480.0463
Subtract 2199 from 2820 to get 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

On to step 13:
6210 divided by 733 is 8 with a remainder of 346.
The next digit of our result is 8. 
Result so far: 100480.04638
If we take 5864 away from 6210, we end up with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

On to step 14:
733 goes into 3460 4 times with a remainder of 528.
Record the quotient 4 as the next digit in the result. 
Result so far: 100480.046384
If we subtract 2932 from 3460, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Step 15:
733 goes into 5280 7 times with a remainder of 149.
Write down 7 as next digit of the result. 
Result so far: 100480.0463847
If we take 5131 away from 5280, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Let's proceed to step 16:
733 can be fit into 1490 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 100480.04638472
The remainder is 24 after subtracting 1466 from 1490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 100480.04638472 with a remainder of 2.4e-08.
