We're dividing 35518261 by 724 
The aim is to understand the frequency of 724 in 35518261.

Let's proceed to step 1:
When dividing 3 by 724, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 724

Let's proceed to step 2:
If we divide 35 by 724, we get 0 and a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Include the next digit (5) from the dividend after 35, then repeat: 355 / 724

Going ahead to step 3:
When dividing 355 by 724, we get 0 with a remainder of 355.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 355 after subtracting 0 from 355.
Include the next digit (1) from the dividend after 355, then repeat: 3551 / 724

Step 4:
If we divide 3551 by 724, we get 4 and a remainder of 655.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 2896 from 3551 and we're left with 655.
Bring next digit (8) of the dividend behind the 655 and repeat the process: 6558 / 724

Going ahead to step 5:
724 can be fit into 6558 9 times, resulting in a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
Deduct 6516 from 6558 and we're left with 42.
Bring next digit (2) of the dividend behind the 42 and repeat the process: 422 / 724

Going ahead to step 6:
The number 724 fits into 422 0 times, leaving a remainder of 422.
Write down 0 as next digit of the result. 
Result so far: 490.0
If we take 0 away from 422, we end up with 422.
Fetch the next digit (6) from the dividend, attach it to 422 and continue: 4226 / 724

Step 7:
When dividing 4226 by 724, we get 5 with a remainder of 606.
The number 5 becomes the next digit in our result. 
Result so far: 4905.0
Subtract 3620 from 4226 to get 606.
Append the next digit (1) from the dividend to 606 and continue with: 6061 / 724

Advancing to step 8:
724 goes into 6061 8 times with a remainder of 269.
Put 8 as the next digit of the answer. 
Result so far: 49058.0
The remainder is 269 after subtracting 5792 from 6061.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Advancing to step 9:
724 goes into 2690 3 times with a remainder of 518.
Write down 3 as next digit of the result. 
Result so far: 49058.3
If we take 2172 away from 2690, we end up with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Going ahead to step 10:
If we divide 5180 by 724, we get 7 and a remainder of 112.
The number 7 becomes the next digit in our result. 
Result so far: 49058.37
Subtracting 5068 from 5180 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 11:
If we divide 1120 by 724, we get 1 and a remainder of 396.
Record the quotient 1 as the next digit in the result. 
Result so far: 49058.371
If we subtract 724 from 1120, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 12:
724 goes into 3960 5 times with a remainder of 340.
Use 5 as the next digit of our solution. 
Result so far: 49058.3715
Deduct 3620 from 3960 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 13:
If we divide 3400 by 724, we get 4 and a remainder of 504.
Put 4 as the next digit of the answer. 
Result so far: 49058.37154
The remainder is 504 after subtracting 2896 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Advancing to step 14:
5040 divided by 724 is 6 with a remainder of 696.
Record the quotient 6 as the next digit in the result. 
Result so far: 49058.371546
Subtract 4344 from 5040 to get 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Moving on to step 15:
6960 divided by 724 is 9 with a remainder of 444.
The number 9 becomes the next digit in our result. 
Result so far: 49058.3715469
If we subtract 6516 from 6960, we get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

On to step 16:
724 can be fit into 4440 6 times, resulting in a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 49058.37154696
The remainder is 96 after subtracting 4344 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The final outcome is 49058.37154696, with a leftover of 9.6e-08.
