17899932 ÷ 878 
We want to figure out the number of times 17899932 can be divided by 878.

Going ahead to step 1:
The number 878 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 878

Moving on to step 2:
17 divided by 878 is 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 878

Let's proceed to step 3:
878 can be fit into 178 0 times, resulting in a remainder of 178.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 178 and we're left with 178.
Fetch the next digit (9) from the dividend, attach it to 178 and continue: 1789 / 878

Advancing to step 4:
878 goes into 1789 2 times with a remainder of 33.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1756 from 1789 leaves us with 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 878

On to step 5:
The number 878 fits into 339 0 times, leaving a remainder of 339.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtracting 0 from 339 leaves us with 339.
Grab the next digit (9) from the dividend, add it to 339, then carry on: 3399 / 878

Moving on to step 6:
878 can be fit into 3399 3 times, resulting in a remainder of 765.
Write down 3 as next digit of the result. 
Result so far: 203.0
Subtract 2634 from 3399 to get 765.
Append the next digit (3) from the dividend to 765 and continue with: 7653 / 878

Advancing to step 7:
If we divide 7653 by 878, we get 8 and a remainder of 629.
Use 8 as the next digit of our solution. 
Result so far: 2038.0
The remainder is 629 after subtracting 7024 from 7653.
Append the next digit (2) from the dividend to 629 and continue with: 6292 / 878

On to step 8:
6292 divided by 878 is 7 with a remainder of 146.
Use 7 as the next digit of our solution. 
Result so far: 20387.0
If we take 6146 away from 6292, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 9:
When dividing 1460 by 878, we get 1 with a remainder of 582.
The next digit of our result is 1. 
Result so far: 20387.1
Deduct 878 from 1460 and we're left with 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Advancing to step 10:
878 can be fit into 5820 6 times, resulting in a remainder of 552.
The number 6 becomes the next digit in our result. 
Result so far: 20387.16
If we subtract 5268 from 5820, we get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 11:
878 goes into 5520 6 times with a remainder of 252.
Write down 6 as next digit of the result. 
Result so far: 20387.166
Subtract 5268 from 5520 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

The quotient of the division is 20387.166, and the remainder is 0.0252.
