We're dividing 22419921 by 878 
We want to figure out the number of times 22419921 can be divided 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.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 878

Step 2:
When dividing 22 by 878, we get 0 with a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Fetch the next digit (4) from the dividend, attach it to 22 and continue: 224 / 878

On to step 3:
The number 878 fits into 224 0 times, leaving a remainder of 224.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 224, we get 224.
Grab the next digit (1) from the dividend, add it to 224, then carry on: 2241 / 878

Going ahead to step 4:
878 goes into 2241 2 times with a remainder of 485.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1756 from 2241 to get 485.
Grab the next digit (9) from the dividend, add it to 485, then carry on: 4859 / 878

Moving on to step 5:
If we divide 4859 by 878, we get 5 and a remainder of 469.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
The remainder is 469 after subtracting 4390 from 4859.
Append the next digit (9) from the dividend to 469 and continue with: 4699 / 878

On to step 6:
878 goes into 4699 5 times with a remainder of 309.
The number 5 becomes the next digit in our result. 
Result so far: 255.0
The remainder is 309 after subtracting 4390 from 4699.
Take the next digit (2) from the dividend and append it to 309, then repeat: 3092 / 878

Let's proceed to step 7:
3092 divided by 878 is 3 with a remainder of 458.
Write down 3 as next digit of the result. 
Result so far: 2553.0
The remainder is 458 after subtracting 2634 from 3092.
Bring next digit (1) of the dividend behind the 458 and repeat the process: 4581 / 878

Moving on to step 8:
When dividing 4581 by 878, we get 5 with a remainder of 191.
Record the quotient 5 as the next digit in the result. 
Result so far: 25535.0
The remainder is 191 after subtracting 4390 from 4581.
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 9:
When dividing 1910 by 878, we get 2 with a remainder of 154.
The next digit of our result is 2. 
Result so far: 25535.2
The remainder is 154 after subtracting 1756 from 1910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 10:
1540 divided by 878 is 1 with a remainder of 662.
Record the quotient 1 as the next digit in the result. 
Result so far: 25535.21
Deduct 878 from 1540 and we're left with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Advancing to step 11:
6620 divided by 878 is 7 with a remainder of 474.
Record the quotient 7 as the next digit in the result. 
Result so far: 25535.217
The remainder is 474 after subtracting 6146 from 6620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Going ahead to step 12:
878 goes into 4740 5 times with a remainder of 350.
Use 5 as the next digit of our solution. 
Result so far: 25535.2175
If we take 4390 away from 4740, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 13:
878 can be fit into 3500 3 times, resulting in a remainder of 866.
The next digit of our result is 3. 
Result so far: 25535.21753
The remainder is 866 after subtracting 2634 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8660, and continue the process.

Advancing to step 14:
878 can be fit into 8660 9 times, resulting in a remainder of 758.
Use 9 as the next digit of our solution. 
Result so far: 25535.217539
The remainder is 758 after subtracting 7902 from 8660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

Let's proceed to step 15:
When dividing 7580 by 878, we get 8 with a remainder of 556.
Write down 8 as next digit of the result. 
Result so far: 25535.2175398
If we subtract 7024 from 7580, we get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Step 16:
5560 divided by 878 is 6 with a remainder of 292.
Put 6 as the next digit of the answer. 
Result so far: 25535.21753986
Deduct 5268 from 5560 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

The final result is 25535.21753986 with a remainder of 2.92e-07.
