Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 638 from 908 to get 270.
Take the next digit (8) from the dividend and append it to 270, then repeat: 2708 / 638

Step 4:
638 can be fit into 2708 4 times, resulting in a remainder of 156.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 2552 from 2708 and we're left with 156.
Append the next digit (5) from the dividend to 156 and continue with: 1565 / 638

Going ahead to step 5:
638 goes into 1565 2 times with a remainder of 289.
The next digit of our result is 2. 
Result so far: 142.0
The remainder is 289 after subtracting 1276 from 1565.
Fetch the next digit (6) from the dividend, attach it to 289 and continue: 2896 / 638

On to step 6:
If we divide 2896 by 638, we get 4 and a remainder of 344.
Put 4 as the next digit of the answer. 
Result so far: 1424.0
Subtract 2552 from 2896 to get 344.
Take the next digit (3) from the dividend and append it to 344, then repeat: 3443 / 638

Advancing to step 7:
If we divide 3443 by 638, we get 5 and a remainder of 253.
Record the quotient 5 as the next digit in the result. 
Result so far: 14245.0
Deduct 3190 from 3443 and we're left with 253.
Take the next digit (4) from the dividend and append it to 253, then repeat: 2534 / 638

Let's proceed to step 8:
If we divide 2534 by 638, we get 3 and a remainder of 620.
The next digit of our result is 3. 
Result so far: 142453.0
If we take 1914 away from 2534, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 9:
If we divide 6200 by 638, we get 9 and a remainder of 458.
Record the quotient 9 as the next digit in the result. 
Result so far: 142453.9
If we take 5742 away from 6200, we end up with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Let's proceed to step 10:
4580 divided by 638 is 7 with a remainder of 114.
Write down 7 as next digit of the result. 
Result so far: 142453.97
If we take 4466 away from 4580, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 11:
If we divide 1140 by 638, we get 1 and a remainder of 502.
The next digit of our result is 1. 
Result so far: 142453.971
Subtract 638 from 1140 to get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Going ahead to step 12:
638 goes into 5020 7 times with a remainder of 554.
Use 7 as the next digit of our solution. 
Result so far: 142453.9717
Subtract 4466 from 5020 to get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

On to step 13:
When dividing 5540 by 638, we get 8 with a remainder of 436.
The number 8 becomes the next digit in our result. 
Result so far: 142453.97178
If we subtract 5104 from 5540, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Step 14:
The number 638 fits into 4360 6 times, leaving a remainder of 532.
Use 6 as the next digit of our solution. 
Result so far: 142453.971786
Subtract 3828 from 4360 to get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

On to step 15:
5320 divided by 638 is 8 with a remainder of 216.
Write down 8 as next digit of the result. 
Result so far: 142453.9717868
If we subtract 5104 from 5320, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 16:
2160 divided by 638 is 3 with a remainder of 246.
Write down 3 as next digit of the result. 
Result so far: 142453.97178683
If we subtract 1914 from 2160, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

In conclusion, the division gives 142453.97178683 with a balance of 2.46e-07.
