8813215 ÷ 649 
Let's see how many times 649 fits into 8813215.

Advancing to step 1:
8 divided by 649 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 649

Going ahead to step 2:
88 divided by 649 is 0 with a remainder of 88.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Include the next digit (1) from the dividend after 88, then repeat: 881 / 649

On to step 3:
649 can be fit into 881 1 times, resulting in a remainder of 232.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 649 from 881, we get 232.
Fetch the next digit (3) from the dividend, attach it to 232 and continue: 2323 / 649

Step 4:
2323 divided by 649 is 3 with a remainder of 376.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 1947 away from 2323, we end up with 376.
Include the next digit (2) from the dividend after 376, then repeat: 3762 / 649

Step 5:
649 goes into 3762 5 times with a remainder of 517.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
If we subtract 3245 from 3762, we get 517.
Grab the next digit (1) from the dividend, add it to 517, then carry on: 5171 / 649

Advancing to step 6:
If we divide 5171 by 649, we get 7 and a remainder of 628.
Record the quotient 7 as the next digit in the result. 
Result so far: 1357.0
If we take 4543 away from 5171, we end up with 628.
Fetch the next digit (5) from the dividend, attach it to 628 and continue: 6285 / 649

Moving on to step 7:
The number 649 fits into 6285 9 times, leaving a remainder of 444.
Write down 9 as next digit of the result. 
Result so far: 13579.0
If we subtract 5841 from 6285, we get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Going ahead to step 8:
4440 divided by 649 is 6 with a remainder of 546.
The next digit of our result is 6. 
Result so far: 13579.6
The remainder is 546 after subtracting 3894 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Let's proceed to step 9:
649 goes into 5460 8 times with a remainder of 268.
Put 8 as the next digit of the answer. 
Result so far: 13579.68
Subtract 5192 from 5460 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Step 10:
The number 649 fits into 2680 4 times, leaving a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 13579.684
The remainder is 84 after subtracting 2596 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 11:
The number 649 fits into 840 1 times, leaving a remainder of 191.
Record the quotient 1 as the next digit in the result. 
Result so far: 13579.6841
The remainder is 191 after subtracting 649 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

On to step 12:
When dividing 1910 by 649, we get 2 with a remainder of 612.
The next digit of our result is 2. 
Result so far: 13579.68412
Deduct 1298 from 1910 and we're left with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Step 13:
If we divide 6120 by 649, we get 9 and a remainder of 279.
Use 9 as the next digit of our solution. 
Result so far: 13579.684129
The remainder is 279 after subtracting 5841 from 6120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Let's proceed to step 14:
The number 649 fits into 2790 4 times, leaving a remainder of 194.
Write down 4 as next digit of the result. 
Result so far: 13579.6841294
If we subtract 2596 from 2790, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Step 15:
1940 divided by 649 is 2 with a remainder of 642.
Record the quotient 2 as the next digit in the result. 
Result so far: 13579.68412942
Subtract 1298 from 1940 to get 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

The final result is 13579.68412942 with a remainder of 6.42e-07.
