We divide 25998493 by 638
Our goal is to divide 25998493 by 638.

Going ahead to step 1:
638 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 638

Step 2:
If we divide 25 by 638, we get 0 and a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 638

Moving on to step 3:
When dividing 259 by 638, we get 0 with a remainder of 259.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 259, we get 259.
Append the next digit (9) from the dividend to 259 and continue with: 2599 / 638

Going ahead to step 4:
2599 divided by 638 is 4 with a remainder of 47.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 2552 from 2599 to get 47.
Grab the next digit (8) from the dividend, add it to 47, then carry on: 478 / 638

Let's proceed to step 5:
When dividing 478 by 638, we get 0 with a remainder of 478.
The next digit of our result is 0. 
Result so far: 40.0
Deduct 0 from 478 and we're left with 478.
Fetch the next digit (4) from the dividend, attach it to 478 and continue: 4784 / 638

On to step 6:
4784 divided by 638 is 7 with a remainder of 318.
Put 7 as the next digit of the answer. 
Result so far: 407.0
Subtract 4466 from 4784 to get 318.
Take the next digit (9) from the dividend and append it to 318, then repeat: 3189 / 638

Going ahead to step 7:
The number 638 fits into 3189 4 times, leaving a remainder of 637.
Record the quotient 4 as the next digit in the result. 
Result so far: 4074.0
Subtract 2552 from 3189 to get 637.
Include the next digit (3) from the dividend after 637, then repeat: 6373 / 638

Going ahead to step 8:
638 can be fit into 6373 9 times, resulting in a remainder of 631.
Write down 9 as next digit of the result. 
Result so far: 40749.0
Deduct 5742 from 6373 and we're left with 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

Step 9:
If we divide 6310 by 638, we get 9 and a remainder of 568.
Use 9 as the next digit of our solution. 
Result so far: 40749.9
Subtracting 5742 from 6310 leaves us with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Advancing to step 10:
If we divide 5680 by 638, we get 8 and a remainder of 576.
Put 8 as the next digit of the answer. 
Result so far: 40749.98
Subtracting 5104 from 5680 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Step 11:
The number 638 fits into 5760 9 times, leaving a remainder of 18.
The next digit of our result is 9. 
Result so far: 40749.989
Subtract 5742 from 5760 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
638 can be fit into 180 0 times, resulting in a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 40749.989
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 13:
If we divide 1800 by 638, we get 2 and a remainder of 524.
Use 2 as the next digit of our solution. 
Result so far: 40749.98902
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.

Step 14:
If we divide 5240 by 638, we get 8 and a remainder of 136.
The next digit of our result is 8. 
Result so far: 40749.989028
Deduct 5104 from 5240 and we're left 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.

Step 15:
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: 40749.9890282
Deduct 1276 from 1360 and we're left 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.

Step 16:
If we divide 840 by 638, we get 1 and a remainder of 202.
Record the quotient 1 as the next digit in the result. 
Result so far: 40749.98902821
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.

Our division results in 40749.98902821 with a remaining 2.02e-07.
