We look at the division of 15299958 by 353 
We're looking to find how many times 353 goes into 15299958.

Step 1:
When dividing 1 by 353, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 353

Moving on to step 2:
353 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 353

Step 3:
353 can be fit into 152 0 times, resulting in a remainder of 152.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 152 after subtracting 0 from 152.
Append the next digit (9) from the dividend to 152 and continue with: 1529 / 353

Moving on to step 4:
353 can be fit into 1529 4 times, resulting in a remainder of 117.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 1412 from 1529, we get 117.
Bring next digit (9) of the dividend behind the 117 and repeat the process: 1179 / 353

On to step 5:
353 can be fit into 1179 3 times, resulting in a remainder of 120.
Write down 3 as next digit of the result. 
Result so far: 43.0
Subtract 1059 from 1179 to get 120.
Take the next digit (9) from the dividend and append it to 120, then repeat: 1209 / 353

Advancing to step 6:
353 goes into 1209 3 times with a remainder of 150.
Use 3 as the next digit of our solution. 
Result so far: 433.0
The remainder is 150 after subtracting 1059 from 1209.
Fetch the next digit (5) from the dividend, attach it to 150 and continue: 1505 / 353

On to step 7:
353 goes into 1505 4 times with a remainder of 93.
Use 4 as the next digit of our solution. 
Result so far: 4334.0
If we subtract 1412 from 1505, we get 93.
Fetch the next digit (8) from the dividend, attach it to 93 and continue: 938 / 353

Step 8:
If we divide 938 by 353, we get 2 and a remainder of 232.
Write down 2 as next digit of the result. 
Result so far: 43342.0
Subtracting 706 from 938 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 9:
2320 divided by 353 is 6 with a remainder of 202.
Write down 6 as next digit of the result. 
Result so far: 43342.6
Subtract 2118 from 2320 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 10:
When dividing 2020 by 353, we get 5 with a remainder of 255.
Write down 5 as next digit of the result. 
Result so far: 43342.65
If we subtract 1765 from 2020, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 11:
The number 353 fits into 2550 7 times, leaving a remainder of 79.
The next digit of our result is 7. 
Result so far: 43342.657
Subtract 2471 from 2550 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 12:
When dividing 790 by 353, we get 2 with a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 43342.6572
Deduct 706 from 790 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 13:
When dividing 840 by 353, we get 2 with a remainder of 134.
Write down 2 as next digit of the result. 
Result so far: 43342.65722
Subtract 706 from 840 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

After the division, we end up with 43342.65722 and a remainder of 0.000134.
