We look at the division of 42819341 by 102 
Let's see how many times 102 fits into 42819341.

Step 1:
When dividing 4 by 102, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 102

Moving on to step 2:
If we divide 42 by 102, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 102

Let's proceed to step 3:
If we divide 428 by 102, we get 4 and a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 20 after subtracting 408 from 428.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 102

Step 4:
102 goes into 201 1 times with a remainder of 99.
Write down 1 as next digit of the result. 
Result so far: 41.0
If we take 102 away from 201, we end up with 99.
Bring next digit (9) of the dividend behind the 99 and repeat the process: 999 / 102

Moving on to step 5:
When dividing 999 by 102, we get 9 with a remainder of 81.
Record the quotient 9 as the next digit in the result. 
Result so far: 419.0
If we subtract 918 from 999, we get 81.
Include the next digit (3) from the dividend after 81, then repeat: 813 / 102

Going ahead to step 6:
If we divide 813 by 102, we get 7 and a remainder of 99.
Put 7 as the next digit of the answer. 
Result so far: 4197.0
Deduct 714 from 813 and we're left with 99.
Include the next digit (4) from the dividend after 99, then repeat: 994 / 102

Going ahead to step 7:
102 can be fit into 994 9 times, resulting in a remainder of 76.
The next digit of our result is 9. 
Result so far: 41979.0
Subtract 918 from 994 to get 76.
Fetch the next digit (1) from the dividend, attach it to 76 and continue: 761 / 102

Advancing to step 8:
102 goes into 761 7 times with a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 419797.0
Deduct 714 from 761 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 9:
The number 102 fits into 470 4 times, leaving a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 419797.4
If we take 408 away from 470, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
620 divided by 102 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 419797.46
Subtracting 612 from 620 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
102 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 419797.46
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
If we divide 800 by 102, we get 7 and a remainder of 86.
Put 7 as the next digit of the answer. 
Result so far: 419797.4607
If we subtract 714 from 800, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 13:
102 goes into 860 8 times with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 419797.46078
The remainder is 44 after subtracting 816 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 14:
When dividing 440 by 102, we get 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 419797.460784
If we take 408 away from 440, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 15:
The number 102 fits into 320 3 times, leaving a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 419797.4607843
If we take 306 away from 320, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 16:
If we divide 140 by 102, we get 1 and a remainder of 38.
The next digit of our result is 1. 
Result so far: 419797.46078431
Subtracting 102 from 140 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

In conclusion, the division gives 419797.46078431 with a balance of 3.8e-08.
