19761350 divided by 638 
We're looking to find how many times 638 goes into 19761350.

Step 1:
638 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 638

Step 2:
19 divided by 638 is 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 638

Step 3:
If we divide 197 by 638, we get 0 and a remainder of 197.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 197 after subtracting 0 from 197.
Bring next digit (6) of the dividend behind the 197 and repeat the process: 1976 / 638

Going ahead to step 4:
The number 638 fits into 1976 3 times, leaving a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 1914 from 1976 to get 62.
Include the next digit (1) from the dividend after 62, then repeat: 621 / 638

On to step 5:
621 divided by 638 is 0 with a remainder of 621.
The next digit of our result is 0. 
Result so far: 30.0
If we take 0 away from 621, we end up with 621.
Include the next digit (3) from the dividend after 621, then repeat: 6213 / 638

Step 6:
638 can be fit into 6213 9 times, resulting in a remainder of 471.
The number 9 becomes the next digit in our result. 
Result so far: 309.0
Deduct 5742 from 6213 and we're left with 471.
Grab the next digit (5) from the dividend, add it to 471, then carry on: 4715 / 638

Moving on to step 7:
638 can be fit into 4715 7 times, resulting in a remainder of 249.
Record the quotient 7 as the next digit in the result. 
Result so far: 3097.0
The remainder is 249 after subtracting 4466 from 4715.
Include the next digit (0) from the dividend after 249, then repeat: 2490 / 638

Moving on to step 8:
The number 638 fits into 2490 3 times, leaving a remainder of 576.
Record the quotient 3 as the next digit in the result. 
Result so far: 30973.0
If we subtract 1914 from 2490, we get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 9:
The number 638 fits into 5760 9 times, leaving a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 30973.9
Subtracting 5742 from 5760 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
The number 638 fits into 180 0 times, leaving a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 30973.9
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 11:
638 can be fit into 1800 2 times, resulting in a remainder of 524.
Put 2 as the next digit of the answer. 
Result so far: 30973.902
The remainder is 524 after subtracting 1276 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Going ahead to step 12:
When dividing 5240 by 638, we get 8 with a remainder of 136.
Put 8 as the next digit of the answer. 
Result so far: 30973.9028
Subtracting 5104 from 5240 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 13:
638 can be fit into 1360 2 times, resulting in a remainder of 84.
Put 2 as the next digit of the answer. 
Result so far: 30973.90282
Subtracting 1276 from 1360 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 14:
840 divided by 638 is 1 with a remainder of 202.
Put 1 as the next digit of the answer. 
Result so far: 30973.902821
Subtracting 638 from 840 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 15:
When dividing 2020 by 638, we get 3 with a remainder of 106.
The number 3 becomes the next digit in our result. 
Result so far: 30973.9028213
If we subtract 1914 from 2020, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 16:
The number 638 fits into 1060 1 times, leaving a remainder of 422.
The number 1 becomes the next digit in our result. 
Result so far: 30973.90282131
Deduct 638 from 1060 and we're left with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

After the division, we end up with 30973.90282131 and a remainder of 4.22e-07.
