We look at the division of 3709853 by 723 
The aim is to understand the frequency of 723 in 3709853.

Advancing to step 1:
723 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 723

On to step 2:
37 divided by 723 is 0 with a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Bring next digit (0) of the dividend behind the 37 and repeat the process: 370 / 723

Moving on to step 3:
The number 723 fits into 370 0 times, leaving a remainder of 370.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 370 to get 370.
Fetch the next digit (9) from the dividend, attach it to 370 and continue: 3709 / 723

Step 4:
723 can be fit into 3709 5 times, resulting in a remainder of 94.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 94 after subtracting 3615 from 3709.
Grab the next digit (8) from the dividend, add it to 94, then carry on: 948 / 723

Moving on to step 5:
If we divide 948 by 723, we get 1 and a remainder of 225.
Put 1 as the next digit of the answer. 
Result so far: 51.0
If we subtract 723 from 948, we get 225.
Include the next digit (5) from the dividend after 225, then repeat: 2255 / 723

Moving on to step 6:
If we divide 2255 by 723, we get 3 and a remainder of 86.
Write down 3 as next digit of the result. 
Result so far: 513.0
Subtract 2169 from 2255 to get 86.
Append the next digit (3) from the dividend to 86 and continue with: 863 / 723

Let's proceed to step 7:
863 divided by 723 is 1 with a remainder of 140.
Put 1 as the next digit of the answer. 
Result so far: 5131.0
Subtracting 723 from 863 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 8:
723 goes into 1400 1 times with a remainder of 677.
Record the quotient 1 as the next digit in the result. 
Result so far: 5131.1
If we take 723 away from 1400, we end up with 677.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

Advancing to step 9:
When dividing 6770 by 723, we get 9 with a remainder of 263.
Write down 9 as next digit of the result. 
Result so far: 5131.19
The remainder is 263 after subtracting 6507 from 6770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Advancing to step 10:
723 goes into 2630 3 times with a remainder of 461.
Write down 3 as next digit of the result. 
Result so far: 5131.193
Deduct 2169 from 2630 and we're left with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Step 11:
If we divide 4610 by 723, we get 6 and a remainder of 272.
Use 6 as the next digit of our solution. 
Result so far: 5131.1936
The remainder is 272 after subtracting 4338 from 4610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 12:
When dividing 2720 by 723, we get 3 with a remainder of 551.
The number 3 becomes the next digit in our result. 
Result so far: 5131.19363
The remainder is 551 after subtracting 2169 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Moving on to step 13:
When dividing 5510 by 723, we get 7 with a remainder of 449.
Put 7 as the next digit of the answer. 
Result so far: 5131.193637
If we subtract 5061 from 5510, we get 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Going ahead to step 14:
The number 723 fits into 4490 6 times, leaving a remainder of 152.
The number 6 becomes the next digit in our result. 
Result so far: 5131.1936376
The remainder is 152 after subtracting 4338 from 4490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 15:
If we divide 1520 by 723, we get 2 and a remainder of 74.
Write down 2 as next digit of the result. 
Result so far: 5131.19363762
If we take 1446 away from 1520, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

In conclusion, the division gives 5131.19363762 with a balance of 7.4e-08.
