We divide 103840 by 42
Our goal is to divide 103840 by 42.

On to step 1:
The number 42 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 42

Let's proceed to step 2:
The number 42 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 42

Let's proceed to step 3:
When dividing 103 by 42, we get 2 with a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 84 away from 103, we end up with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 42

Moving on to step 4:
If we divide 198 by 42, we get 4 and a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 24.0
Deduct 168 from 198 and we're left with 30.
Bring next digit (4) of the dividend behind the 30 and repeat the process: 304 / 42

Going ahead to step 5:
When dividing 304 by 42, we get 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 247.0
If we subtract 294 from 304, we get 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 42

On to step 6:
42 goes into 100 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 2472.0
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
The number 42 fits into 160 3 times, leaving a remainder of 34.
The next digit of our result is 3. 
Result so far: 2472.3
If we take 126 away from 160, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 2472.38
Subtracting 336 from 340 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
The number 42 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 2472.38
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
42 goes into 400 9 times with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 2472.3809
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
220 divided by 42 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 2472.38095
If we take 210 away from 220, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
42 can be fit into 100 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 2472.380952
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
When dividing 160 by 42, we get 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 2472.3809523
If we take 126 away from 160, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 14:
340 divided by 42 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 2472.38095238
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 2472.38095238, with a leftover of 4e-09.
