We're dividing 17813778 by 638 
Let's see how many times 638 fits into 17813778.

On to step 1:
638 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 638

Step 2:
638 can be fit into 17 0 times, resulting in a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 638

Advancing to step 3:
When dividing 178 by 638, we get 0 with a remainder of 178.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 178 and we're left with 178.
Grab the next digit (1) from the dividend, add it to 178, then carry on: 1781 / 638

Advancing to step 4:
If we divide 1781 by 638, we get 2 and a remainder of 505.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1276 away from 1781, we end up with 505.
Bring next digit (3) of the dividend behind the 505 and repeat the process: 5053 / 638

Let's proceed to step 5:
When dividing 5053 by 638, we get 7 with a remainder of 587.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Deduct 4466 from 5053 and we're left with 587.
Include the next digit (7) from the dividend after 587, then repeat: 5877 / 638

Let's proceed to step 6:
638 can be fit into 5877 9 times, resulting in a remainder of 135.
Write down 9 as next digit of the result. 
Result so far: 279.0
Deduct 5742 from 5877 and we're left with 135.
Take the next digit (7) from the dividend and append it to 135, then repeat: 1357 / 638

Step 7:
The number 638 fits into 1357 2 times, leaving a remainder of 81.
The number 2 becomes the next digit in our result. 
Result so far: 2792.0
If we subtract 1276 from 1357, we get 81.
Bring next digit (8) of the dividend behind the 81 and repeat the process: 818 / 638

On to step 8:
If we divide 818 by 638, we get 1 and a remainder of 180.
The number 1 becomes the next digit in our result. 
Result so far: 27921.0
The remainder is 180 after subtracting 638 from 818.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 9:
When dividing 1800 by 638, we get 2 with a remainder of 524.
The number 2 becomes the next digit in our result. 
Result so far: 27921.2
Subtracting 1276 from 1800 leaves us with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Let's proceed to step 10:
638 can be fit into 5240 8 times, resulting in a remainder of 136.
Put 8 as the next digit of the answer. 
Result so far: 27921.28
The remainder is 136 after subtracting 5104 from 5240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 11:
638 goes into 1360 2 times with a remainder of 84.
Write down 2 as next digit of the result. 
Result so far: 27921.282
If we subtract 1276 from 1360, we get 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 12:
638 goes into 840 1 times with a remainder of 202.
Put 1 as the next digit of the answer. 
Result so far: 27921.2821
If we subtract 638 from 840, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 13:
638 goes into 2020 3 times with a remainder of 106.
Put 3 as the next digit of the answer. 
Result so far: 27921.28213
The remainder is 106 after subtracting 1914 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 14:
638 goes into 1060 1 times with a remainder of 422.
Record the quotient 1 as the next digit in the result. 
Result so far: 27921.282131
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.

Moving on to step 15:
The number 638 fits into 4220 6 times, leaving a remainder of 392.
Use 6 as the next digit of our solution. 
Result so far: 27921.2821316
Subtracting 3828 from 4220 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 16:
When dividing 3920 by 638, we get 6 with a remainder of 92.
The next digit of our result is 6. 
Result so far: 27921.28213166
Subtracting 3828 from 3920 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Our division results in 27921.28213166 with a remaining 9.2e-08.
