70553418 divided by 815 
Let's see how many times 815 fits into 70553418.

On to step 1:
815 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 815

Going ahead to step 2:
815 can be fit into 70 0 times, resulting in a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Include the next digit (5) from the dividend after 70, then repeat: 705 / 815

Step 3:
When dividing 705 by 815, we get 0 with a remainder of 705.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 705, we end up with 705.
Include the next digit (5) from the dividend after 705, then repeat: 7055 / 815

Step 4:
The number 815 fits into 7055 8 times, leaving a remainder of 535.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 6520 from 7055, we get 535.
Include the next digit (3) from the dividend after 535, then repeat: 5353 / 815

On to step 5:
815 can be fit into 5353 6 times, resulting in a remainder of 463.
The next digit of our result is 6. 
Result so far: 86.0
Subtracting 4890 from 5353 leaves us with 463.
Grab the next digit (4) from the dividend, add it to 463, then carry on: 4634 / 815

Let's proceed to step 6:
815 goes into 4634 5 times with a remainder of 559.
Write down 5 as next digit of the result. 
Result so far: 865.0
If we take 4075 away from 4634, we end up with 559.
Fetch the next digit (1) from the dividend, attach it to 559 and continue: 5591 / 815

Let's proceed to step 7:
815 goes into 5591 6 times with a remainder of 701.
Put 6 as the next digit of the answer. 
Result so far: 8656.0
If we take 4890 away from 5591, we end up with 701.
Include the next digit (8) from the dividend after 701, then repeat: 7018 / 815

Step 8:
When dividing 7018 by 815, we get 8 with a remainder of 498.
Record the quotient 8 as the next digit in the result. 
Result so far: 86568.0
The remainder is 498 after subtracting 6520 from 7018.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

On to step 9:
4980 divided by 815 is 6 with a remainder of 90.
Put 6 as the next digit of the answer. 
Result so far: 86568.6
If we take 4890 away from 4980, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
815 can be fit into 900 1 times, resulting in a remainder of 85.
The next digit of our result is 1. 
Result so far: 86568.61
If we take 815 away from 900, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 11:
815 goes into 850 1 times with a remainder of 35.
The next digit of our result is 1. 
Result so far: 86568.611
Deduct 815 from 850 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 86568.611 with a remaining 0.0035.
