We're dividing 2345457 by 638 
We want to divide 2345457 by 638.

Step 1:
638 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 638

Advancing to step 2:
When dividing 23 by 638, we get 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Fetch the next digit (4) from the dividend, attach it to 23 and continue: 234 / 638

Going ahead to step 3:
638 can be fit into 234 0 times, resulting in a remainder of 234.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 234 after subtracting 0 from 234.
Take the next digit (5) from the dividend and append it to 234, then repeat: 2345 / 638

On to step 4:
If we divide 2345 by 638, we get 3 and a remainder of 431.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 1914 from 2345 leaves us with 431.
Grab the next digit (4) from the dividend, add it to 431, then carry on: 4314 / 638

Let's proceed to step 5:
638 can be fit into 4314 6 times, resulting in a remainder of 486.
The next digit of our result is 6. 
Result so far: 36.0
The remainder is 486 after subtracting 3828 from 4314.
Fetch the next digit (5) from the dividend, attach it to 486 and continue: 4865 / 638

Advancing to step 6:
4865 divided by 638 is 7 with a remainder of 399.
Put 7 as the next digit of the answer. 
Result so far: 367.0
If we take 4466 away from 4865, we end up with 399.
Include the next digit (7) from the dividend after 399, then repeat: 3997 / 638

On to step 7:
638 goes into 3997 6 times with a remainder of 169.
Use 6 as the next digit of our solution. 
Result so far: 3676.0
Subtract 3828 from 3997 to get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Advancing to step 8:
638 goes into 1690 2 times with a remainder of 414.
Put 2 as the next digit of the answer. 
Result so far: 3676.2
Deduct 1276 from 1690 and we're left 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.

Moving on to step 9:
4140 divided by 638 is 6 with a remainder of 312.
Write down 6 as next digit of the result. 
Result so far: 3676.26
The remainder is 312 after subtracting 3828 from 4140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 10:
The number 638 fits into 3120 4 times, leaving a remainder of 568.
Write down 4 as next digit of the result. 
Result so far: 3676.264
Subtract 2552 from 3120 to 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.

Advancing to step 11:
The number 638 fits into 5680 8 times, leaving a remainder of 576.
Record the quotient 8 as the next digit in the result. 
Result so far: 3676.2648
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.

Advancing to step 12:
When dividing 5760 by 638, we get 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 3676.26489
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.

On to step 13:
638 can be fit into 180 0 times, resulting in a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 3676.26489
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.

Let's proceed to step 14:
The number 638 fits into 1800 2 times, leaving a remainder of 524.
Put 2 as the next digit of the answer. 
Result so far: 3676.2648902
Deduct 1276 from 1800 and we're left 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.

On to step 15:
When dividing 5240 by 638, we get 8 with a remainder of 136.
Record the quotient 8 as the next digit in the result. 
Result so far: 3676.26489028
Subtract 5104 from 5240 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Our division results in 3676.26489028 with a remaining 1.36e-07.
