We look at the division of 42104718 by 342 
We want to divide 42104718 by 342.

Let's proceed to step 1:
The number 342 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 342

Going ahead to step 2:
342 can be fit into 42 0 times, resulting in a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 342

On to step 3:
421 divided by 342 is 1 with a remainder of 79.
The next digit of our result is 1. 
Result so far: 1.0
If we take 342 away from 421, we end up with 79.
Bring next digit (0) of the dividend behind the 79 and repeat the process: 790 / 342

Going ahead to step 4:
790 divided by 342 is 2 with a remainder of 106.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 684 from 790 leaves us with 106.
Grab the next digit (4) from the dividend, add it to 106, then carry on: 1064 / 342

Going ahead to step 5:
1064 divided by 342 is 3 with a remainder of 38.
The next digit of our result is 3. 
Result so far: 123.0
The remainder is 38 after subtracting 1026 from 1064.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 342

On to step 6:
If we divide 387 by 342, we get 1 and a remainder of 45.
The next digit of our result is 1. 
Result so far: 1231.0
Subtracting 342 from 387 leaves us with 45.
Grab the next digit (1) from the dividend, add it to 45, then carry on: 451 / 342

Advancing to step 7:
When dividing 451 by 342, we get 1 with a remainder of 109.
The number 1 becomes the next digit in our result. 
Result so far: 12311.0
If we take 342 away from 451, we end up with 109.
Fetch the next digit (8) from the dividend, attach it to 109 and continue: 1098 / 342

Let's proceed to step 8:
342 goes into 1098 3 times with a remainder of 72.
Write down 3 as next digit of the result. 
Result so far: 123113.0
If we take 1026 away from 1098, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 9:
342 goes into 720 2 times with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 123113.2
The remainder is 36 after subtracting 684 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
342 can be fit into 360 1 times, resulting in a remainder of 18.
The next digit of our result is 1. 
Result so far: 123113.21
If we take 342 away from 360, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
The number 342 fits into 180 0 times, leaving a remainder of 180.
The next digit of our result is 0. 
Result so far: 123113.21
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 12:
When dividing 1800 by 342, we get 5 with a remainder of 90.
The next digit of our result is 5. 
Result so far: 123113.2105
If we take 1710 away from 1800, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 13:
900 divided by 342 is 2 with a remainder of 216.
The number 2 becomes the next digit in our result. 
Result so far: 123113.21052
Subtracting 684 from 900 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 14:
2160 divided by 342 is 6 with a remainder of 108.
Record the quotient 6 as the next digit in the result. 
Result so far: 123113.210526
If we take 2052 away from 2160, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 15:
When dividing 1080 by 342, we get 3 with a remainder of 54.
The next digit of our result is 3. 
Result so far: 123113.2105263
If we take 1026 away from 1080, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 16:
When dividing 540 by 342, we get 1 with a remainder of 198.
Use 1 as the next digit of our solution. 
Result so far: 123113.21052631
Subtract 342 from 540 to 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.

After the division, we end up with 123113.21052631 and a remainder of 1.98e-07.
