We look at the division of 6351207 by 638 
Our goal is to divide 6351207 by 638.

Let's proceed to step 1:
When dividing 6 by 638, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 638

Step 2:
If we divide 63 by 638, we get 0 and a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Grab the next digit (5) from the dividend, add it to 63, then carry on: 635 / 638

Advancing to step 3:
638 can be fit into 635 0 times, resulting in a remainder of 635.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 635 and we're left with 635.
Append the next digit (1) from the dividend to 635 and continue with: 6351 / 638

Let's proceed to step 4:
The number 638 fits into 6351 9 times, leaving a remainder of 609.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 5742 away from 6351, we end up with 609.
Bring next digit (2) of the dividend behind the 609 and repeat the process: 6092 / 638

Going ahead to step 5:
6092 divided by 638 is 9 with a remainder of 350.
Write down 9 as next digit of the result. 
Result so far: 99.0
If we subtract 5742 from 6092, we get 350.
Take the next digit (0) from the dividend and append it to 350, then repeat: 3500 / 638

Step 6:
When dividing 3500 by 638, we get 5 with a remainder of 310.
Record the quotient 5 as the next digit in the result. 
Result so far: 995.0
If we subtract 3190 from 3500, we get 310.
Bring next digit (7) of the dividend behind the 310 and repeat the process: 3107 / 638

Advancing to step 7:
The number 638 fits into 3107 4 times, leaving a remainder of 555.
The next digit of our result is 4. 
Result so far: 9954.0
Subtracting 2552 from 3107 leaves us with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Let's proceed to step 8:
638 can be fit into 5550 8 times, resulting in a remainder of 446.
Use 8 as the next digit of our solution. 
Result so far: 9954.8
If we take 5104 away from 5550, we end up with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

On to step 9:
638 goes into 4460 6 times with a remainder of 632.
Use 6 as the next digit of our solution. 
Result so far: 9954.86
The remainder is 632 after subtracting 3828 from 4460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Advancing to step 10:
The number 638 fits into 6320 9 times, leaving a remainder of 578.
The number 9 becomes the next digit in our result. 
Result so far: 9954.869
If we take 5742 away from 6320, we end up with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Step 11:
If we divide 5780 by 638, we get 9 and a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 9954.8699
Subtract 5742 from 5780 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 9954.8699 with a remaining 0.00038.
