34463370 ÷ 815 
Our goal is to divide 34463370 by 815.

Let's proceed 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
If we take 0 away from 3, we end up with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 815

Advancing to step 2:
815 goes into 34 0 times with a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Bring next digit (4) of the dividend behind the 34 and repeat the process: 344 / 815

On to step 3:
When dividing 344 by 815, we get 0 with a remainder of 344.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 344 to get 344.
Grab the next digit (6) from the dividend, add it to 344, then carry on: 3446 / 815

Let's proceed to step 4:
815 goes into 3446 4 times with a remainder of 186.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 3260 away from 3446, we end up with 186.
Grab the next digit (3) from the dividend, add it to 186, then carry on: 1863 / 815

Going ahead to step 5:
If we divide 1863 by 815, we get 2 and a remainder of 233.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtract 1630 from 1863 to get 233.
Grab the next digit (3) from the dividend, add it to 233, then carry on: 2333 / 815

Going ahead to step 6:
When dividing 2333 by 815, we get 2 with a remainder of 703.
Record the quotient 2 as the next digit in the result. 
Result so far: 422.0
If we subtract 1630 from 2333, we get 703.
Append the next digit (7) from the dividend to 703 and continue with: 7037 / 815

Step 7:
When dividing 7037 by 815, we get 8 with a remainder of 517.
Use 8 as the next digit of our solution. 
Result so far: 4228.0
If we subtract 6520 from 7037, we get 517.
Grab the next digit (0) from the dividend, add it to 517, then carry on: 5170 / 815

Going ahead to step 8:
5170 divided by 815 is 6 with a remainder of 280.
Put 6 as the next digit of the answer. 
Result so far: 42286.0
The remainder is 280 after subtracting 4890 from 5170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 9:
2800 divided by 815 is 3 with a remainder of 355.
The number 3 becomes the next digit in our result. 
Result so far: 42286.3
The remainder is 355 after subtracting 2445 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Step 10:
If we divide 3550 by 815, we get 4 and a remainder of 290.
Put 4 as the next digit of the answer. 
Result so far: 42286.34
If we take 3260 away from 3550, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 11:
If we divide 2900 by 815, we get 3 and a remainder of 455.
Put 3 as the next digit of the answer. 
Result so far: 42286.343
Subtract 2445 from 2900 to get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

On to step 12:
If we divide 4550 by 815, we get 5 and a remainder of 475.
The next digit of our result is 5. 
Result so far: 42286.3435
The remainder is 475 after subtracting 4075 from 4550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Step 13:
815 goes into 4750 5 times with a remainder of 675.
Put 5 as the next digit of the answer. 
Result so far: 42286.34355
Subtracting 4075 from 4750 leaves us with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

After the division, we end up with 42286.34355 and a remainder of 0.000675.
