We look at the division of 21494112 by 878 
We want to divide 21494112 by 878.

Advancing to step 1:
2 divided by 878 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 878

Step 2:
878 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 878

Step 3:
878 can be fit into 214 0 times, resulting in a remainder of 214.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 214, we get 214.
Include the next digit (9) from the dividend after 214, then repeat: 2149 / 878

Advancing to step 4:
2149 divided by 878 is 2 with a remainder of 393.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 1756 away from 2149, we end up with 393.
Include the next digit (4) from the dividend after 393, then repeat: 3934 / 878

Step 5:
3934 divided by 878 is 4 with a remainder of 422.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we take 3512 away from 3934, we end up with 422.
Bring next digit (1) of the dividend behind the 422 and repeat the process: 4221 / 878

Let's proceed to step 6:
The number 878 fits into 4221 4 times, leaving a remainder of 709.
Record the quotient 4 as the next digit in the result. 
Result so far: 244.0
The remainder is 709 after subtracting 3512 from 4221.
Fetch the next digit (1) from the dividend, attach it to 709 and continue: 7091 / 878

On to step 7:
7091 divided by 878 is 8 with a remainder of 67.
The next digit of our result is 8. 
Result so far: 2448.0
If we subtract 7024 from 7091, we get 67.
Grab the next digit (2) from the dividend, add it to 67, then carry on: 672 / 878

Going ahead to step 8:
When dividing 672 by 878, we get 0 with a remainder of 672.
The next digit of our result is 0. 
Result so far: 24480.0
Subtract 0 from 672 to get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

On to step 9:
878 goes into 6720 7 times with a remainder of 574.
The number 7 becomes the next digit in our result. 
Result so far: 24480.7
Subtracting 6146 from 6720 leaves us with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Going ahead to step 10:
The number 878 fits into 5740 6 times, leaving a remainder of 472.
Use 6 as the next digit of our solution. 
Result so far: 24480.76
Subtract 5268 from 5740 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 11:
The number 878 fits into 4720 5 times, leaving a remainder of 330.
The next digit of our result is 5. 
Result so far: 24480.765
Subtracting 4390 from 4720 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 12:
878 goes into 3300 3 times with a remainder of 666.
Use 3 as the next digit of our solution. 
Result so far: 24480.7653
The remainder is 666 after subtracting 2634 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Going ahead to step 13:
878 can be fit into 6660 7 times, resulting in a remainder of 514.
Write down 7 as next digit of the result. 
Result so far: 24480.76537
If we take 6146 away from 6660, we end up with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Advancing to step 14:
When dividing 5140 by 878, we get 5 with a remainder of 750.
Put 5 as the next digit of the answer. 
Result so far: 24480.765375
Deduct 4390 from 5140 and we're left with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Step 15:
878 can be fit into 7500 8 times, resulting in a remainder of 476.
Put 8 as the next digit of the answer. 
Result so far: 24480.7653758
Deduct 7024 from 7500 and we're left with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Moving on to step 16:
4760 divided by 878 is 5 with a remainder of 370.
The number 5 becomes the next digit in our result. 
Result so far: 24480.76537585
Subtract 4390 from 4760 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

The quotient of the division is 24480.76537585, and the remainder is 3.7e-07.
