Let's divide 3574019 by 357
The aim is to understand the frequency of 357 in 3574019.

Step 1:
When dividing 3 by 357, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 357

Let's proceed to step 2:
35 divided by 357 is 0 with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Fetch the next digit (7) from the dividend, attach it to 35 and continue: 357 / 357

Going ahead to step 3:
357 can be fit into 357 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 357 from 357 and we're left with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 357

Step 4:
If we divide 4 by 357, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 357

Let's proceed to step 5:
357 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
If we subtract 0 from 40, we get 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 357

On to step 6:
401 divided by 357 is 1 with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 1001.0
If we take 357 away from 401, we end up with 44.
Grab the next digit (9) from the dividend, add it to 44, then carry on: 449 / 357

Let's proceed to step 7:
357 goes into 449 1 times with a remainder of 92.
The number 1 becomes the next digit in our result. 
Result so far: 10011.0
Subtract 357 from 449 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 8:
920 divided by 357 is 2 with a remainder of 206.
Write down 2 as next digit of the result. 
Result so far: 10011.2
If we subtract 714 from 920, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 9:
If we divide 2060 by 357, we get 5 and a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 10011.25
The remainder is 275 after subtracting 1785 from 2060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 10:
357 goes into 2750 7 times with a remainder of 251.
Write down 7 as next digit of the result. 
Result so far: 10011.257
If we take 2499 away from 2750, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

On to step 11:
If we divide 2510 by 357, we get 7 and a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 10011.2577
If we take 2499 away from 2510, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 10011.2577 with a remainder of 0.00011.
