We divide 40354233 by 638
We want to figure out the number of times 40354233 can be divided by 638.

Going ahead to step 1:
When dividing 4 by 638, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 638

Moving on to step 2:
If we divide 40 by 638, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Append the next digit (3) from the dividend to 40 and continue with: 403 / 638

Advancing to step 3:
638 goes into 403 0 times with a remainder of 403.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 403 to get 403.
Fetch the next digit (5) from the dividend, attach it to 403 and continue: 4035 / 638

Advancing to step 4:
When dividing 4035 by 638, we get 6 with a remainder of 207.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 3828 away from 4035, we end up with 207.
Take the next digit (4) from the dividend and append it to 207, then repeat: 2074 / 638

Going ahead to step 5:
The number 638 fits into 2074 3 times, leaving a remainder of 160.
Write down 3 as next digit of the result. 
Result so far: 63.0
Subtracting 1914 from 2074 leaves us with 160.
Include the next digit (2) from the dividend after 160, then repeat: 1602 / 638

Moving on to step 6:
The number 638 fits into 1602 2 times, leaving a remainder of 326.
The next digit of our result is 2. 
Result so far: 632.0
Deduct 1276 from 1602 and we're left with 326.
Include the next digit (3) from the dividend after 326, then repeat: 3263 / 638

Going ahead to step 7:
The number 638 fits into 3263 5 times, leaving a remainder of 73.
The next digit of our result is 5. 
Result so far: 6325.0
If we subtract 3190 from 3263, we get 73.
Fetch the next digit (3) from the dividend, attach it to 73 and continue: 733 / 638

Let's proceed to step 8:
When dividing 733 by 638, we get 1 with a remainder of 95.
Record the quotient 1 as the next digit in the result. 
Result so far: 63251.0
Deduct 638 from 733 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 9:
638 can be fit into 950 1 times, resulting in a remainder of 312.
The number 1 becomes the next digit in our result. 
Result so far: 63251.1
Subtract 638 from 950 to 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.

Let's proceed to step 10:
The number 638 fits into 3120 4 times, leaving a remainder of 568.
Record the quotient 4 as the next digit in the result. 
Result so far: 63251.14
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.

Step 11:
The number 638 fits into 5680 8 times, leaving a remainder of 576.
The next digit of our result is 8. 
Result so far: 63251.148
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:
If we divide 5760 by 638, we get 9 and a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 63251.1489
If we subtract 5742 from 5760, we 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 13:
The number 638 fits into 180 0 times, leaving a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 63251.1489
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 14:
638 goes into 1800 2 times with a remainder of 524.
Put 2 as the next digit of the answer. 
Result so far: 63251.148902
If we take 1276 away from 1800, we end up 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.

Advancing to step 15:
638 goes into 5240 8 times with a remainder of 136.
Write down 8 as next digit of the result. 
Result so far: 63251.1489028
Subtracting 5104 from 5240 leaves us 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 16:
When dividing 1360 by 638, we get 2 with a remainder of 84.
The next digit of our result is 2. 
Result so far: 63251.14890282
The remainder is 84 after subtracting 1276 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

After the division, we end up with 63251.14890282 and a remainder of 8.4e-08.
