Let's divide 10215624 by 886
We want to divide 10215624 by 886.

On to step 1:
If we divide 1 by 886, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 886

Let's proceed to step 2:
If we divide 10 by 886, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 886

On to step 3:
The number 886 fits into 102 0 times, leaving a remainder of 102.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 102 to get 102.
Include the next digit (1) from the dividend after 102, then repeat: 1021 / 886

Advancing to step 4:
If we divide 1021 by 886, we get 1 and a remainder of 135.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 886 from 1021 to get 135.
Grab the next digit (5) from the dividend, add it to 135, then carry on: 1355 / 886

Step 5:
The number 886 fits into 1355 1 times, leaving a remainder of 469.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 886 from 1355 and we're left with 469.
Bring next digit (6) of the dividend behind the 469 and repeat the process: 4696 / 886

Going ahead to step 6:
4696 divided by 886 is 5 with a remainder of 266.
Put 5 as the next digit of the answer. 
Result so far: 115.0
Subtract 4430 from 4696 to get 266.
Take the next digit (2) from the dividend and append it to 266, then repeat: 2662 / 886

Advancing to step 7:
886 goes into 2662 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 1153.0
The remainder is 4 after subtracting 2658 from 2662.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 886

Let's proceed to step 8:
44 divided by 886 is 0 with a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 11530.0
If we subtract 0 from 44, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
440 divided by 886 is 0 with a remainder of 440.
The next digit of our result is 0. 
Result so far: 11530.0
Subtracting 0 from 440 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 10:
When dividing 4400 by 886, we get 4 with a remainder of 856.
Record the quotient 4 as the next digit in the result. 
Result so far: 11530.04
Subtract 3544 from 4400 to get 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Going ahead to step 11:
When dividing 8560 by 886, we get 9 with a remainder of 586.
The number 9 becomes the next digit in our result. 
Result so far: 11530.049
If we take 7974 away from 8560, we end up with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Going ahead to step 12:
When dividing 5860 by 886, we get 6 with a remainder of 544.
The next digit of our result is 6. 
Result so far: 11530.0496
Subtracting 5316 from 5860 leaves us with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Moving on to step 13:
When dividing 5440 by 886, we get 6 with a remainder of 124.
The number 6 becomes the next digit in our result. 
Result so far: 11530.04966
If we subtract 5316 from 5440, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final result is 11530.04966 with a remainder of 0.000124.
