We look at the division of 20042595 by 678 
Our goal is to divide 20042595 by 678.

Let's proceed to step 1:
When dividing 2 by 678, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 678

On to step 2:
678 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 678

Let's proceed to step 3:
678 goes into 200 0 times with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 200, we end up with 200.
Grab the next digit (4) from the dividend, add it to 200, then carry on: 2004 / 678

Let's proceed to step 4:
678 goes into 2004 2 times with a remainder of 648.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 648 after subtracting 1356 from 2004.
Take the next digit (2) from the dividend and append it to 648, then repeat: 6482 / 678

Moving on to step 5:
678 can be fit into 6482 9 times, resulting in a remainder of 380.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Deduct 6102 from 6482 and we're left with 380.
Fetch the next digit (5) from the dividend, attach it to 380 and continue: 3805 / 678

On to step 6:
The number 678 fits into 3805 5 times, leaving a remainder of 415.
The next digit of our result is 5. 
Result so far: 295.0
If we take 3390 away from 3805, we end up with 415.
Bring next digit (9) of the dividend behind the 415 and repeat the process: 4159 / 678

Advancing to step 7:
When dividing 4159 by 678, we get 6 with a remainder of 91.
The next digit of our result is 6. 
Result so far: 2956.0
The remainder is 91 after subtracting 4068 from 4159.
Bring next digit (5) of the dividend behind the 91 and repeat the process: 915 / 678

Step 8:
When dividing 915 by 678, we get 1 with a remainder of 237.
Use 1 as the next digit of our solution. 
Result so far: 29561.0
If we take 678 away from 915, we end up with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Step 9:
When dividing 2370 by 678, we get 3 with a remainder of 336.
Use 3 as the next digit of our solution. 
Result so far: 29561.3
Subtracting 2034 from 2370 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 10:
678 goes into 3360 4 times with a remainder of 648.
Record the quotient 4 as the next digit in the result. 
Result so far: 29561.34
Deduct 2712 from 3360 and we're left with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Going ahead to step 11:
678 can be fit into 6480 9 times, resulting in a remainder of 378.
The next digit of our result is 9. 
Result so far: 29561.349
If we subtract 6102 from 6480, we get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Let's proceed to step 12:
If we divide 3780 by 678, we get 5 and a remainder of 390.
Write down 5 as next digit of the result. 
Result so far: 29561.3495
Subtracting 3390 from 3780 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 13:
If we divide 3900 by 678, we get 5 and a remainder of 510.
Use 5 as the next digit of our solution. 
Result so far: 29561.34955
Subtract 3390 from 3900 to get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

The final outcome is 29561.34955, with a leftover of 0.00051.
