12863766 ÷ 884 
We want to figure out the number of times 12863766 can be divided by 884.

Let's proceed to step 1:
884 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 884

On to step 2:
884 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 884

Let's proceed to step 3:
If we divide 128 by 884, we get 0 and a remainder of 128.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 128 to get 128.
Append the next digit (6) from the dividend to 128 and continue with: 1286 / 884

On to step 4:
884 can be fit into 1286 1 times, resulting in a remainder of 402.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 884 away from 1286, we end up with 402.
Grab the next digit (3) from the dividend, add it to 402, then carry on: 4023 / 884

Advancing to step 5:
884 goes into 4023 4 times with a remainder of 487.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 3536 from 4023 and we're left with 487.
Fetch the next digit (7) from the dividend, attach it to 487 and continue: 4877 / 884

Going ahead to step 6:
884 can be fit into 4877 5 times, resulting in a remainder of 457.
The next digit of our result is 5. 
Result so far: 145.0
Subtract 4420 from 4877 to get 457.
Bring next digit (6) of the dividend behind the 457 and repeat the process: 4576 / 884

Moving on to step 7:
If we divide 4576 by 884, we get 5 and a remainder of 156.
The next digit of our result is 5. 
Result so far: 1455.0
Subtracting 4420 from 4576 leaves us with 156.
Fetch the next digit (6) from the dividend, attach it to 156 and continue: 1566 / 884

On to step 8:
When dividing 1566 by 884, we get 1 with a remainder of 682.
Write down 1 as next digit of the result. 
Result so far: 14551.0
Subtracting 884 from 1566 leaves us with 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Advancing to step 9:
884 goes into 6820 7 times with a remainder of 632.
The number 7 becomes the next digit in our result. 
Result so far: 14551.7
Subtracting 6188 from 6820 leaves us with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

On to step 10:
When dividing 6320 by 884, we get 7 with a remainder of 132.
The number 7 becomes the next digit in our result. 
Result so far: 14551.77
If we take 6188 away from 6320, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The quotient of the division is 14551.77, and the remainder is 0.132.
