Let's divide 29258939 by 353
The aim is to understand the frequency of 353 in 29258939.

Going ahead to step 1:
353 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
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 / 353

Let's proceed to step 2:
353 goes into 29 0 times with a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 353

Step 3:
The number 353 fits into 292 0 times, leaving a remainder of 292.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 292 to get 292.
Include the next digit (5) from the dividend after 292, then repeat: 2925 / 353

Advancing to step 4:
When dividing 2925 by 353, we get 8 with a remainder of 101.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 2824 from 2925 and we're left with 101.
Fetch the next digit (8) from the dividend, attach it to 101 and continue: 1018 / 353

Advancing to step 5:
The number 353 fits into 1018 2 times, leaving a remainder of 312.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
Subtracting 706 from 1018 leaves us with 312.
Bring next digit (9) of the dividend behind the 312 and repeat the process: 3129 / 353

Advancing to step 6:
When dividing 3129 by 353, we get 8 with a remainder of 305.
The number 8 becomes the next digit in our result. 
Result so far: 828.0
If we take 2824 away from 3129, we end up with 305.
Bring next digit (3) of the dividend behind the 305 and repeat the process: 3053 / 353

On to step 7:
When dividing 3053 by 353, we get 8 with a remainder of 229.
Put 8 as the next digit of the answer. 
Result so far: 8288.0
Subtract 2824 from 3053 to get 229.
Include the next digit (9) from the dividend after 229, then repeat: 2299 / 353

Moving on to step 8:
The number 353 fits into 2299 6 times, leaving a remainder of 181.
Put 6 as the next digit of the answer. 
Result so far: 82886.0
Deduct 2118 from 2299 and we're left with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 9:
353 goes into 1810 5 times with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 82886.5
If we take 1765 away from 1810, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 10:
353 can be fit into 450 1 times, resulting in a remainder of 97.
Record the quotient 1 as the next digit in the result. 
Result so far: 82886.51
If we take 353 away from 450, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 11:
353 can be fit into 970 2 times, resulting in a remainder of 264.
Record the quotient 2 as the next digit in the result. 
Result so far: 82886.512
Subtracting 706 from 970 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 12:
353 goes into 2640 7 times with a remainder of 169.
Record the quotient 7 as the next digit in the result. 
Result so far: 82886.5127
Subtract 2471 from 2640 to get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

On to step 13:
353 goes into 1690 4 times with a remainder of 278.
Use 4 as the next digit of our solution. 
Result so far: 82886.51274
If we take 1412 away from 1690, we end up with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 14:
The number 353 fits into 2780 7 times, leaving a remainder of 309.
Put 7 as the next digit of the answer. 
Result so far: 82886.512747
Subtracting 2471 from 2780 leaves us with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Let's proceed to step 15:
When dividing 3090 by 353, we get 8 with a remainder of 266.
Put 8 as the next digit of the answer. 
Result so far: 82886.5127478
Subtract 2824 from 3090 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 16:
If we divide 2660 by 353, we get 7 and a remainder of 189.
The number 7 becomes the next digit in our result. 
Result so far: 82886.51274787
The remainder is 189 after subtracting 2471 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

The final result is 82886.51274787 with a remainder of 1.89e-07.
