19863414 divided by 342 
Our goal is to divide 19863414 by 342.

Going ahead to step 1:
342 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 342

Advancing to step 2:
The number 342 fits into 19 0 times, leaving a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 342

On to step 3:
342 goes into 198 0 times with a remainder of 198.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 198, we get 198.
Append the next digit (6) from the dividend to 198 and continue with: 1986 / 342

On to step 4:
342 goes into 1986 5 times with a remainder of 276.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 276 after subtracting 1710 from 1986.
Include the next digit (3) from the dividend after 276, then repeat: 2763 / 342

On to step 5:
The number 342 fits into 2763 8 times, leaving a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
Deduct 2736 from 2763 and we're left with 27.
Bring next digit (4) of the dividend behind the 27 and repeat the process: 274 / 342

Going ahead to step 6:
If we divide 274 by 342, we get 0 and a remainder of 274.
Use 0 as the next digit of our solution. 
Result so far: 580.0
The remainder is 274 after subtracting 0 from 274.
Take the next digit (1) from the dividend and append it to 274, then repeat: 2741 / 342

Going ahead to step 7:
342 can be fit into 2741 8 times, resulting in a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 5808.0
If we take 2736 away from 2741, we end up with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 342

Advancing to step 8:
The number 342 fits into 54 0 times, leaving a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 58080.0
If we subtract 0 from 54, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 9:
The number 342 fits into 540 1 times, leaving a remainder of 198.
Record the quotient 1 as the next digit in the result. 
Result so far: 58080.1
If we subtract 342 from 540, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 10:
If we divide 1980 by 342, we get 5 and a remainder of 270.
Write down 5 as next digit of the result. 
Result so far: 58080.15
If we take 1710 away from 1980, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 11:
2700 divided by 342 is 7 with a remainder of 306.
The next digit of our result is 7. 
Result so far: 58080.157
Subtract 2394 from 2700 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Moving on to step 12:
3060 divided by 342 is 8 with a remainder of 324.
Record the quotient 8 as the next digit in the result. 
Result so far: 58080.1578
Subtracting 2736 from 3060 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Moving on to step 13:
The number 342 fits into 3240 9 times, leaving a remainder of 162.
The next digit of our result is 9. 
Result so far: 58080.15789
If we subtract 3078 from 3240, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 14:
342 can be fit into 1620 4 times, resulting in a remainder of 252.
Record the quotient 4 as the next digit in the result. 
Result so far: 58080.157894
If we subtract 1368 from 1620, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 15:
If we divide 2520 by 342, we get 7 and a remainder of 126.
Use 7 as the next digit of our solution. 
Result so far: 58080.1578947
The remainder is 126 after subtracting 2394 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 16:
342 goes into 1260 3 times with a remainder of 234.
Put 3 as the next digit of the answer. 
Result so far: 58080.15789473
Subtracting 1026 from 1260 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

The final outcome is 58080.15789473, with a leftover of 2.34e-07.
