19878540 divided by 938 
We want to figure out the number of times 19878540 can be divided by 938.

Moving on to step 1:
938 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 938

Step 2:
19 divided by 938 is 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 938

Let's proceed to step 3:
If we divide 198 by 938, we get 0 and a remainder of 198.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 198 to get 198.
Bring next digit (7) of the dividend behind the 198 and repeat the process: 1987 / 938

Going ahead to step 4:
The number 938 fits into 1987 2 times, leaving a remainder of 111.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 111 after subtracting 1876 from 1987.
Fetch the next digit (8) from the dividend, attach it to 111 and continue: 1118 / 938

Advancing to step 5:
If we divide 1118 by 938, we get 1 and a remainder of 180.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtract 938 from 1118 to get 180.
Include the next digit (5) from the dividend after 180, then repeat: 1805 / 938

Step 6:
If we divide 1805 by 938, we get 1 and a remainder of 867.
The number 1 becomes the next digit in our result. 
Result so far: 211.0
Deduct 938 from 1805 and we're left with 867.
Fetch the next digit (4) from the dividend, attach it to 867 and continue: 8674 / 938

Going ahead to step 7:
8674 divided by 938 is 9 with a remainder of 232.
The next digit of our result is 9. 
Result so far: 2119.0
If we take 8442 away from 8674, we end up with 232.
Include the next digit (0) from the dividend after 232, then repeat: 2320 / 938

Moving on to step 8:
The number 938 fits into 2320 2 times, leaving a remainder of 444.
Record the quotient 2 as the next digit in the result. 
Result so far: 21192.0
Deduct 1876 from 2320 and we're left with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Step 9:
4440 divided by 938 is 4 with a remainder of 688.
The number 4 becomes the next digit in our result. 
Result so far: 21192.4
The remainder is 688 after subtracting 3752 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Advancing to step 10:
6880 divided by 938 is 7 with a remainder of 314.
Record the quotient 7 as the next digit in the result. 
Result so far: 21192.47
The remainder is 314 after subtracting 6566 from 6880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 11:
The number 938 fits into 3140 3 times, leaving a remainder of 326.
The next digit of our result is 3. 
Result so far: 21192.473
The remainder is 326 after subtracting 2814 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Moving on to step 12:
If we divide 3260 by 938, we get 3 and a remainder of 446.
Put 3 as the next digit of the answer. 
Result so far: 21192.4733
If we subtract 2814 from 3260, we get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Our division results in 21192.4733 with a remaining 0.00446.
