19818351 ÷ 358 
Our goal is to divide 19818351 by 358.

Let's proceed to step 1:
1 divided by 358 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 358

Moving on to step 2:
358 goes into 19 0 times with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 358

Let's proceed to step 3:
358 can be fit into 198 0 times, resulting in a remainder of 198.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 198 and we're left with 198.
Take the next digit (1) from the dividend and append it to 198, then repeat: 1981 / 358

Moving on to step 4:
358 can be fit into 1981 5 times, resulting in a remainder of 191.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 191 after subtracting 1790 from 1981.
Include the next digit (8) from the dividend after 191, then repeat: 1918 / 358

Going ahead to step 5:
If we divide 1918 by 358, we get 5 and a remainder of 128.
Put 5 as the next digit of the answer. 
Result so far: 55.0
Subtracting 1790 from 1918 leaves us with 128.
Include the next digit (3) from the dividend after 128, then repeat: 1283 / 358

Advancing to step 6:
The number 358 fits into 1283 3 times, leaving a remainder of 209.
The next digit of our result is 3. 
Result so far: 553.0
Deduct 1074 from 1283 and we're left with 209.
Fetch the next digit (5) from the dividend, attach it to 209 and continue: 2095 / 358

Let's proceed to step 7:
2095 divided by 358 is 5 with a remainder of 305.
Record the quotient 5 as the next digit in the result. 
Result so far: 5535.0
If we subtract 1790 from 2095, we get 305.
Include the next digit (1) from the dividend after 305, then repeat: 3051 / 358

Moving on to step 8:
If we divide 3051 by 358, we get 8 and a remainder of 187.
Use 8 as the next digit of our solution. 
Result so far: 55358.0
The remainder is 187 after subtracting 2864 from 3051.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 9:
The number 358 fits into 1870 5 times, leaving a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 55358.5
If we subtract 1790 from 1870, 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.

Going ahead to step 10:
358 can be fit into 800 2 times, resulting in a remainder of 84.
Use 2 as the next digit of our solution. 
Result so far: 55358.52
Deduct 716 from 800 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.

Step 11:
If we divide 840 by 358, we get 2 and a remainder of 124.
Record the quotient 2 as the next digit in the result. 
Result so far: 55358.522
Subtracting 716 from 840 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final outcome is 55358.522, with a leftover of 0.0124.
