We're dividing 15191306 by 342 
We want to figure out the number of times 15191306 can be divided by 342.

Let's proceed to step 1:
342 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 342

On to step 2:
When dividing 15 by 342, we get 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 342

Moving on to step 3:
If we divide 151 by 342, we get 0 and a remainder of 151.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 151 to get 151.
Bring next digit (9) of the dividend behind the 151 and repeat the process: 1519 / 342

Going ahead to step 4:
If we divide 1519 by 342, we get 4 and a remainder of 151.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 1368 from 1519 to get 151.
Grab the next digit (1) from the dividend, add it to 151, then carry on: 1511 / 342

Advancing to step 5:
When dividing 1511 by 342, we get 4 with a remainder of 143.
Put 4 as the next digit of the answer. 
Result so far: 44.0
If we subtract 1368 from 1511, we get 143.
Include the next digit (3) from the dividend after 143, then repeat: 1433 / 342

Going ahead to step 6:
1433 divided by 342 is 4 with a remainder of 65.
The next digit of our result is 4. 
Result so far: 444.0
Subtract 1368 from 1433 to get 65.
Fetch the next digit (0) from the dividend, attach it to 65 and continue: 650 / 342

Step 7:
650 divided by 342 is 1 with a remainder of 308.
Put 1 as the next digit of the answer. 
Result so far: 4441.0
The remainder is 308 after subtracting 342 from 650.
Fetch the next digit (6) from the dividend, attach it to 308 and continue: 3086 / 342

On to step 8:
3086 divided by 342 is 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 44419.0
The remainder is 8 after subtracting 3078 from 3086.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
342 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 44419.0
Deduct 0 from 80 and we're left with 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:
342 can be fit into 800 2 times, resulting in a remainder of 116.
Put 2 as the next digit of the answer. 
Result so far: 44419.02
Subtracting 684 from 800 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 11:
If we divide 1160 by 342, we get 3 and a remainder of 134.
Write down 3 as next digit of the result. 
Result so far: 44419.023
Subtracting 1026 from 1160 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 12:
The number 342 fits into 1340 3 times, leaving a remainder of 314.
The number 3 becomes the next digit in our result. 
Result so far: 44419.0233
The remainder is 314 after subtracting 1026 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

The final result is 44419.0233 with a remainder of 0.00314.
