84342678 divided by 815 
We're looking to find how many times 815 goes into 84342678.

Advancing to step 1:
If we divide 8 by 815, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 815

Moving on to step 2:
815 goes into 84 0 times with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Include the next digit (3) from the dividend after 84, then repeat: 843 / 815

Let's proceed to step 3:
815 goes into 843 1 times with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 28 after subtracting 815 from 843.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 815

Advancing to step 4:
815 can be fit into 284 0 times, resulting in a remainder of 284.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 284 and we're left with 284.
Take the next digit (2) from the dividend and append it to 284, then repeat: 2842 / 815

Going ahead to step 5:
815 can be fit into 2842 3 times, resulting in a remainder of 397.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
Deduct 2445 from 2842 and we're left with 397.
Take the next digit (6) from the dividend and append it to 397, then repeat: 3976 / 815

On to step 6:
When dividing 3976 by 815, we get 4 with a remainder of 716.
Put 4 as the next digit of the answer. 
Result so far: 1034.0
The remainder is 716 after subtracting 3260 from 3976.
Fetch the next digit (7) from the dividend, attach it to 716 and continue: 7167 / 815

Advancing to step 7:
7167 divided by 815 is 8 with a remainder of 647.
Use 8 as the next digit of our solution. 
Result so far: 10348.0
If we subtract 6520 from 7167, we get 647.
Fetch the next digit (8) from the dividend, attach it to 647 and continue: 6478 / 815

Advancing to step 8:
When dividing 6478 by 815, we get 7 with a remainder of 773.
The next digit of our result is 7. 
Result so far: 103487.0
Deduct 5705 from 6478 and we're left with 773.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7730, and continue the process.

On to step 9:
If we divide 7730 by 815, we get 9 and a remainder of 395.
Put 9 as the next digit of the answer. 
Result so far: 103487.9
If we take 7335 away from 7730, we end up with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Step 10:
815 can be fit into 3950 4 times, resulting in a remainder of 690.
Record the quotient 4 as the next digit in the result. 
Result so far: 103487.94
If we take 3260 away from 3950, we end up with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Going ahead to step 11:
If we divide 6900 by 815, we get 8 and a remainder of 380.
Record the quotient 8 as the next digit in the result. 
Result so far: 103487.948
If we subtract 6520 from 6900, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 12:
815 can be fit into 3800 4 times, resulting in a remainder of 540.
Use 4 as the next digit of our solution. 
Result so far: 103487.9484
Subtracting 3260 from 3800 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Moving on to step 13:
If we divide 5400 by 815, we get 6 and a remainder of 510.
Put 6 as the next digit of the answer. 
Result so far: 103487.94846
Subtract 4890 from 5400 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.

Moving on to step 14:
815 can be fit into 5100 6 times, resulting in a remainder of 210.
The number 6 becomes the next digit in our result. 
Result so far: 103487.948466
If we subtract 4890 from 5100, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final outcome is 103487.948466, with a leftover of 2.1e-05.
