We're dividing 29004193 by 350 
The aim is to understand the frequency of 350 in 29004193.

On to step 1:
2 divided by 350 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 350

Let's proceed to step 2:
29 divided by 350 is 0 with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 350

On to step 3:
When dividing 290 by 350, we get 0 with a remainder of 290.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 290 after subtracting 0 from 290.
Grab the next digit (0) from the dividend, add it to 290, then carry on: 2900 / 350

Step 4:
When dividing 2900 by 350, we get 8 with a remainder of 100.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 2800 away from 2900, we end up with 100.
Grab the next digit (4) from the dividend, add it to 100, then carry on: 1004 / 350

Step 5:
350 can be fit into 1004 2 times, resulting in a remainder of 304.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
Subtracting 700 from 1004 leaves us with 304.
Include the next digit (1) from the dividend after 304, then repeat: 3041 / 350

Advancing to step 6:
350 can be fit into 3041 8 times, resulting in a remainder of 241.
Write down 8 as next digit of the result. 
Result so far: 828.0
Deduct 2800 from 3041 and we're left with 241.
Bring next digit (9) of the dividend behind the 241 and repeat the process: 2419 / 350

Step 7:
350 goes into 2419 6 times with a remainder of 319.
The next digit of our result is 6. 
Result so far: 8286.0
The remainder is 319 after subtracting 2100 from 2419.
Include the next digit (3) from the dividend after 319, then repeat: 3193 / 350

Going ahead to step 8:
3193 divided by 350 is 9 with a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 82869.0
If we take 3150 away from 3193, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
350 goes into 430 1 times with a remainder of 80.
The next digit of our result is 1. 
Result so far: 82869.1
If we subtract 350 from 430, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
If we divide 800 by 350, we get 2 and a remainder of 100.
The number 2 becomes the next digit in our result. 
Result so far: 82869.12
Subtracting 700 from 800 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
1000 divided by 350 is 2 with a remainder of 300.
Record the quotient 2 as the next digit in the result. 
Result so far: 82869.122
If we subtract 700 from 1000, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 82869.122 with a remaining 0.03.
