Let's divide 42351293 by 819
Let's see how many times 819 fits into 42351293.

Going ahead to step 1:
The number 819 fits into 4 0 times, leaving 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.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 819

Advancing to step 2:
The number 819 fits into 42 0 times, leaving 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.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 819

Let's proceed to step 3:
The number 819 fits into 423 0 times, leaving a remainder of 423.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 423 after subtracting 0 from 423.
Bring next digit (5) of the dividend behind the 423 and repeat the process: 4235 / 819

Step 4:
819 can be fit into 4235 5 times, resulting in a remainder of 140.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 4095 from 4235 to get 140.
Include the next digit (1) from the dividend after 140, then repeat: 1401 / 819

Let's proceed to step 5:
1401 divided by 819 is 1 with a remainder of 582.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we subtract 819 from 1401, we get 582.
Take the next digit (2) from the dividend and append it to 582, then repeat: 5822 / 819

Moving on to step 6:
819 can be fit into 5822 7 times, resulting in a remainder of 89.
The number 7 becomes the next digit in our result. 
Result so far: 517.0
The remainder is 89 after subtracting 5733 from 5822.
Include the next digit (9) from the dividend after 89, then repeat: 899 / 819

Going ahead to step 7:
When dividing 899 by 819, we get 1 with a remainder of 80.
Put 1 as the next digit of the answer. 
Result so far: 5171.0
Deduct 819 from 899 and we're left with 80.
Take the next digit (3) from the dividend and append it to 80, then repeat: 803 / 819

Advancing to step 8:
When dividing 803 by 819, we get 0 with a remainder of 803.
Put 0 as the next digit of the answer. 
Result so far: 51710.0
If we subtract 0 from 803, we get 803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8030, and continue the process.

Moving on to step 9:
819 can be fit into 8030 9 times, resulting in a remainder of 659.
Put 9 as the next digit of the answer. 
Result so far: 51710.9
The remainder is 659 after subtracting 7371 from 8030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

Let's proceed to step 10:
819 can be fit into 6590 8 times, resulting in a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 51710.98
Subtracting 6552 from 6590 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.

Going ahead to step 11:
819 goes into 380 0 times with a remainder of 380.
Record the quotient 0 as the next digit in the result. 
Result so far: 51710.98
Subtracting 0 from 380 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 12:
If we divide 3800 by 819, we get 4 and a remainder of 524.
Record the quotient 4 as the next digit in the result. 
Result so far: 51710.9804
Subtract 3276 from 3800 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Moving on to step 13:
The number 819 fits into 5240 6 times, leaving a remainder of 326.
Put 6 as the next digit of the answer. 
Result so far: 51710.98046
Subtracting 4914 from 5240 leaves us with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Moving on to step 14:
The number 819 fits into 3260 3 times, leaving a remainder of 803.
The number 3 becomes the next digit in our result. 
Result so far: 51710.980463
If we subtract 2457 from 3260, we get 803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8030, and continue the process.

Let's proceed to step 15:
When dividing 8030 by 819, we get 9 with a remainder of 659.
Record the quotient 9 as the next digit in the result. 
Result so far: 51710.9804639
If we take 7371 away from 8030, we end up with 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

On to step 16:
If we divide 6590 by 819, we get 8 and a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 51710.98046398
The remainder is 38 after subtracting 6552 from 6590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 51710.98046398 with a remainder of 3.8e-08.
