4 divided by 353 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 353

Going ahead to step 2:
43 divided by 353 is 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Fetch the next digit (4) from the dividend, attach it to 43 and continue: 434 / 353

On to step 3:
The number 353 fits into 434 1 times, leaving a remainder of 81.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 353 from 434, we get 81.
Grab the next digit (9) from the dividend, add it to 81, then carry on: 819 / 353

Let's proceed to step 4:
353 can be fit into 819 2 times, resulting in a remainder of 113.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 706 from 819 leaves us with 113.
Fetch the next digit (7) from the dividend, attach it to 113 and continue: 1137 / 353

Advancing to step 5:
353 can be fit into 1137 3 times, resulting in a remainder of 78.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
Deduct 1059 from 1137 and we're left with 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 353

Going ahead to step 6:
When dividing 788 by 353, we get 2 with a remainder of 82.
Use 2 as the next digit of our solution. 
Result so far: 1232.0
If we subtract 706 from 788, we get 82.
Include the next digit (1) from the dividend after 82, then repeat: 821 / 353

Advancing to step 7:
821 divided by 353 is 2 with a remainder of 115.
The next digit of our result is 2. 
Result so far: 12322.0
Deduct 706 from 821 and we're left with 115.
Append the next digit (6) from the dividend to 115 and continue with: 1156 / 353

Going ahead to step 8:
If we divide 1156 by 353, we get 3 and a remainder of 97.
Put 3 as the next digit of the answer. 
Result so far: 123223.0
If we subtract 1059 from 1156, we get 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 9:
The number 353 fits into 970 2 times, leaving a remainder of 264.
Put 2 as the next digit of the answer. 
Result so far: 123223.2
If we take 706 away from 970, we end up 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.

Step 10:
2640 divided by 353 is 7 with a remainder of 169.
Write down 7 as next digit of the result. 
Result so far: 123223.27
The remainder is 169 after subtracting 2471 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Moving on to step 11:
353 goes into 1690 4 times with a remainder of 278.
The number 4 becomes the next digit in our result. 
Result so far: 123223.274
Deduct 1412 from 1690 and we're left 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.

Going ahead to step 12:
353 can be fit into 2780 7 times, resulting in a remainder of 309.
Use 7 as the next digit of our solution. 
Result so far: 123223.2747
If we subtract 2471 from 2780, we get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Advancing to step 13:
3090 divided by 353 is 8 with a remainder of 266.
The number 8 becomes the next digit in our result. 
Result so far: 123223.27478
If we take 2824 away from 3090, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

On to step 14:
353 can be fit into 2660 7 times, resulting in a remainder of 189.
Use 7 as the next digit of our solution. 
Result so far: 123223.274787
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.

Step 15:
353 goes into 1890 5 times with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 123223.2747875
Subtract 1765 from 1890 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 16:
1250 divided by 353 is 3 with a remainder of 191.
Use 3 as the next digit of our solution. 
Result so far: 123223.27478753
Deduct 1059 from 1250 and we're left with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

The final outcome is 123223.27478753, with a leftover of 1.91e-07.
