On to step 4:
The number 638 fits into 1002 1 times, leaving a remainder of 364.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 638 from 1002 and we're left with 364.
Grab the next digit (1) from the dividend, add it to 364, then carry on: 3641 / 638

Advancing to step 5:
3641 divided by 638 is 5 with a remainder of 451.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
Deduct 3190 from 3641 and we're left with 451.
Bring next digit (3) of the dividend behind the 451 and repeat the process: 4513 / 638

Moving on to step 6:
4513 divided by 638 is 7 with a remainder of 47.
The next digit of our result is 7. 
Result so far: 1157.0
Subtracting 4466 from 4513 leaves us with 47.
Fetch the next digit (5) from the dividend, attach it to 47 and continue: 475 / 638

Going ahead to step 7:
475 divided by 638 is 0 with a remainder of 475.
Write down 0 as next digit of the result. 
Result so far: 11570.0
Deduct 0 from 475 and we're left with 475.
Grab the next digit (9) from the dividend, add it to 475, then carry on: 4759 / 638

Let's proceed to step 8:
The number 638 fits into 4759 7 times, leaving a remainder of 293.
The number 7 becomes the next digit in our result. 
Result so far: 115707.0
Subtracting 4466 from 4759 leaves us with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

On to step 9:
638 goes into 2930 4 times with a remainder of 378.
Use 4 as the next digit of our solution. 
Result so far: 115707.4
Deduct 2552 from 2930 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Moving on to step 10:
The number 638 fits into 3780 5 times, leaving a remainder of 590.
Use 5 as the next digit of our solution. 
Result so far: 115707.45
If we take 3190 away from 3780, we end up with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Let's proceed to step 11:
638 goes into 5900 9 times with a remainder of 158.
Use 9 as the next digit of our solution. 
Result so far: 115707.459
Subtract 5742 from 5900 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 12:
638 goes into 1580 2 times with a remainder of 304.
Put 2 as the next digit of the answer. 
Result so far: 115707.4592
Subtract 1276 from 1580 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 13:
If we divide 3040 by 638, we get 4 and a remainder of 488.
The number 4 becomes the next digit in our result. 
Result so far: 115707.45924
If we subtract 2552 from 3040, we get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Step 14:
If we divide 4880 by 638, we get 7 and a remainder of 414.
The next digit of our result is 7. 
Result so far: 115707.459247
Subtracting 4466 from 4880 leaves us with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Step 15:
4140 divided by 638 is 6 with a remainder of 312.
The next digit of our result is 6. 
Result so far: 115707.4592476
If we subtract 3828 from 4140, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 16:
638 can be fit into 3120 4 times, resulting in a remainder of 568.
The number 4 becomes the next digit in our result. 
Result so far: 115707.45924764
If we subtract 2552 from 3120, we get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Our division results in 115707.45924764 with a remaining 5.68e-07.
