We're dividing 34993870 by 815 
We want to divide 34993870 by 815.

Going ahead to step 1:
815 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 815

Going ahead to step 2:
When dividing 34 by 815, we get 0 with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 815

Advancing to step 3:
When dividing 349 by 815, we get 0 with a remainder of 349.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 349 and we're left with 349.
Grab the next digit (9) from the dividend, add it to 349, then carry on: 3499 / 815

Let's proceed to step 4:
815 can be fit into 3499 4 times, resulting in a remainder of 239.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 3260 from 3499 leaves us with 239.
Include the next digit (3) from the dividend after 239, then repeat: 2393 / 815

On to step 5:
815 can be fit into 2393 2 times, resulting in a remainder of 763.
The next digit of our result is 2. 
Result so far: 42.0
If we subtract 1630 from 2393, we get 763.
Grab the next digit (8) from the dividend, add it to 763, then carry on: 7638 / 815

Going ahead to step 6:
When dividing 7638 by 815, we get 9 with a remainder of 303.
Write down 9 as next digit of the result. 
Result so far: 429.0
If we subtract 7335 from 7638, we get 303.
Bring next digit (7) of the dividend behind the 303 and repeat the process: 3037 / 815

Step 7:
815 goes into 3037 3 times with a remainder of 592.
Use 3 as the next digit of our solution. 
Result so far: 4293.0
Subtracting 2445 from 3037 leaves us with 592.
Include the next digit (0) from the dividend after 592, then repeat: 5920 / 815

On to step 8:
815 goes into 5920 7 times with a remainder of 215.
Write down 7 as next digit of the result. 
Result so far: 42937.0
If we take 5705 away from 5920, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 9:
815 goes into 2150 2 times with a remainder of 520.
Write down 2 as next digit of the result. 
Result so far: 42937.2
Deduct 1630 from 2150 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 10:
815 goes into 5200 6 times with a remainder of 310.
Put 6 as the next digit of the answer. 
Result so far: 42937.26
Subtracting 4890 from 5200 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 11:
The number 815 fits into 3100 3 times, leaving a remainder of 655.
Put 3 as the next digit of the answer. 
Result so far: 42937.263
The remainder is 655 after subtracting 2445 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Moving on to step 12:
When dividing 6550 by 815, we get 8 with a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 42937.2638
Deduct 6520 from 6550 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
815 can be fit into 300 0 times, resulting in a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 42937.2638
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 14:
If we divide 3000 by 815, we get 3 and a remainder of 555.
Write down 3 as next digit of the result. 
Result so far: 42937.263803
The remainder is 555 after subtracting 2445 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Moving on to step 15:
815 goes into 5550 6 times with a remainder of 660.
Write down 6 as next digit of the result. 
Result so far: 42937.2638036
Subtract 4890 from 5550 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Step 16:
815 goes into 6600 8 times with a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 42937.26380368
Deduct 6520 from 6600 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 42937.26380368 with a remainder of 8e-08.
