Let's divide 75517762 by 723
The aim is to understand the frequency of 723 in 75517762.

Step 1:
When dividing 7 by 723, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 723

Going ahead to step 2:
When dividing 75 by 723, we get 0 with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Grab the next digit (5) from the dividend, add it to 75, then carry on: 755 / 723

On to step 3:
If we divide 755 by 723, we get 1 and a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 723 from 755, we get 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 723

Going ahead to step 4:
The number 723 fits into 321 0 times, leaving a remainder of 321.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 321 after subtracting 0 from 321.
Fetch the next digit (7) from the dividend, attach it to 321 and continue: 3217 / 723

Step 5:
When dividing 3217 by 723, we get 4 with a remainder of 325.
Use 4 as the next digit of our solution. 
Result so far: 104.0
The remainder is 325 after subtracting 2892 from 3217.
Grab the next digit (7) from the dividend, add it to 325, then carry on: 3257 / 723

Let's proceed to step 6:
723 can be fit into 3257 4 times, resulting in a remainder of 365.
Write down 4 as next digit of the result. 
Result so far: 1044.0
Subtract 2892 from 3257 to get 365.
Fetch the next digit (6) from the dividend, attach it to 365 and continue: 3656 / 723

On to step 7:
3656 divided by 723 is 5 with a remainder of 41.
Put 5 as the next digit of the answer. 
Result so far: 10445.0
Deduct 3615 from 3656 and we're left with 41.
Include the next digit (2) from the dividend after 41, then repeat: 412 / 723

Let's proceed to step 8:
When dividing 412 by 723, we get 0 with a remainder of 412.
The next digit of our result is 0. 
Result so far: 104450.0
Subtracting 0 from 412 leaves us with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Advancing to step 9:
If we divide 4120 by 723, we get 5 and a remainder of 505.
Use 5 as the next digit of our solution. 
Result so far: 104450.5
Deduct 3615 from 4120 and we're left with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

On to step 10:
When dividing 5050 by 723, we get 6 with a remainder of 712.
Write down 6 as next digit of the result. 
Result so far: 104450.56
If we take 4338 away from 5050, we end up with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Going ahead to step 11:
723 can be fit into 7120 9 times, resulting in a remainder of 613.
Write down 9 as next digit of the result. 
Result so far: 104450.569
Deduct 6507 from 7120 and we're left with 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

Going ahead to step 12:
If we divide 6130 by 723, we get 8 and a remainder of 346.
Put 8 as the next digit of the answer. 
Result so far: 104450.5698
The remainder is 346 after subtracting 5784 from 6130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Advancing to step 13:
The number 723 fits into 3460 4 times, leaving a remainder of 568.
Record the quotient 4 as the next digit in the result. 
Result so far: 104450.56984
Deduct 2892 from 3460 and we're left with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Advancing to step 14:
723 goes into 5680 7 times with a remainder of 619.
The number 7 becomes the next digit in our result. 
Result so far: 104450.569847
Subtracting 5061 from 5680 leaves us with 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Step 15:
When dividing 6190 by 723, we get 8 with a remainder of 406.
The next digit of our result is 8. 
Result so far: 104450.5698478
If we take 5784 away from 6190, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Moving on to step 16:
4060 divided by 723 is 5 with a remainder of 445.
Use 5 as the next digit of our solution. 
Result so far: 104450.56984785
If we subtract 3615 from 4060, we get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

The final outcome is 104450.56984785, with a leftover of 4.45e-07.
