We're dividing 16354901 by 638 
Our goal is to divide 16354901 by 638.

On to step 1:
The number 638 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 638

Step 2:
16 divided by 638 is 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 638

Moving on to step 3:
638 goes into 163 0 times with a remainder of 163.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 163 to get 163.
Append the next digit (5) from the dividend to 163 and continue with: 1635 / 638

Step 4:
1635 divided by 638 is 2 with a remainder of 359.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1276 from 1635, we get 359.
Take the next digit (4) from the dividend and append it to 359, then repeat: 3594 / 638

Step 5:
638 can be fit into 3594 5 times, resulting in a remainder of 404.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 404 after subtracting 3190 from 3594.
Take the next digit (9) from the dividend and append it to 404, then repeat: 4049 / 638

On to step 6:
638 goes into 4049 6 times with a remainder of 221.
The next digit of our result is 6. 
Result so far: 256.0
The remainder is 221 after subtracting 3828 from 4049.
Bring next digit (0) of the dividend behind the 221 and repeat the process: 2210 / 638

Moving on to step 7:
2210 divided by 638 is 3 with a remainder of 296.
Write down 3 as next digit of the result. 
Result so far: 2563.0
If we subtract 1914 from 2210, we get 296.
Grab the next digit (1) from the dividend, add it to 296, then carry on: 2961 / 638

Step 8:
638 goes into 2961 4 times with a remainder of 409.
Use 4 as the next digit of our solution. 
Result so far: 25634.0
If we take 2552 away from 2961, we end up with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

On to step 9:
4090 divided by 638 is 6 with a remainder of 262.
Record the quotient 6 as the next digit in the result. 
Result so far: 25634.6
Subtract 3828 from 4090 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 10:
When dividing 2620 by 638, we get 4 with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 25634.64
Subtract 2552 from 2620 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 11:
680 divided by 638 is 1 with a remainder of 42.
The next digit of our result is 1. 
Result so far: 25634.641
Subtract 638 from 680 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
420 divided by 638 is 0 with a remainder of 420.
Use 0 as the next digit of our solution. 
Result so far: 25634.641
Subtract 0 from 420 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 13:
638 goes into 4200 6 times with a remainder of 372.
The number 6 becomes the next digit in our result. 
Result so far: 25634.64106
Deduct 3828 from 4200 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Moving on to step 14:
638 goes into 3720 5 times with a remainder of 530.
The number 5 becomes the next digit in our result. 
Result so far: 25634.641065
Subtracting 3190 from 3720 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 15:
If we divide 5300 by 638, we get 8 and a remainder of 196.
Put 8 as the next digit of the answer. 
Result so far: 25634.6410658
If we take 5104 away from 5300, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 16:
If we divide 1960 by 638, we get 3 and a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 25634.64106583
Subtracting 1914 from 1960 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The quotient of the division is 25634.64106583, and the remainder is 4.6e-08.
