We divide 73078090 by 638
We want to divide 73078090 by 638.

Let's proceed to step 1:
The number 638 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 638

Moving on to step 2:
73 divided by 638 is 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Grab the next digit (0) from the dividend, add it to 73, then carry on: 730 / 638

On to step 3:
638 can be fit into 730 1 times, resulting in a remainder of 92.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 638 from 730 to get 92.
Include the next digit (7) from the dividend after 92, then repeat: 927 / 638

Moving on to step 4:
927 divided by 638 is 1 with a remainder of 289.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 638 from 927 and we're left with 289.
Fetch the next digit (8) from the dividend, attach it to 289 and continue: 2898 / 638

Let's proceed to step 5:
2898 divided by 638 is 4 with a remainder of 346.
Put 4 as the next digit of the answer. 
Result so far: 114.0
Subtract 2552 from 2898 to get 346.
Bring next digit (0) of the dividend behind the 346 and repeat the process: 3460 / 638

Moving on to step 6:
638 can be fit into 3460 5 times, resulting in a remainder of 270.
The next digit of our result is 5. 
Result so far: 1145.0
If we take 3190 away from 3460, we end up with 270.
Include the next digit (9) from the dividend after 270, then repeat: 2709 / 638

Step 7:
638 can be fit into 2709 4 times, resulting in a remainder of 157.
The next digit of our result is 4. 
Result so far: 11454.0
The remainder is 157 after subtracting 2552 from 2709.
Fetch the next digit (0) from the dividend, attach it to 157 and continue: 1570 / 638

Step 8:
The number 638 fits into 1570 2 times, leaving a remainder of 294.
The next digit of our result is 2. 
Result so far: 114542.0
Subtracting 1276 from 1570 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 9:
If we divide 2940 by 638, we get 4 and a remainder of 388.
Use 4 as the next digit of our solution. 
Result so far: 114542.4
Subtracting 2552 from 2940 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 10:
3880 divided by 638 is 6 with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 114542.46
If we subtract 3828 from 3880, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
If we divide 520 by 638, we get 0 and a remainder of 520.
Write down 0 as next digit of the result. 
Result so far: 114542.46
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 12:
638 goes into 5200 8 times with a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 114542.4608
If we subtract 5104 from 5200, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 13:
The number 638 fits into 960 1 times, leaving a remainder of 322.
Record the quotient 1 as the next digit in the result. 
Result so far: 114542.46081
Subtracting 638 from 960 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 14:
638 can be fit into 3220 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 114542.460815
The remainder is 30 after subtracting 3190 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 15:
638 goes into 300 0 times with a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 114542.460815
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 16:
If we divide 3000 by 638, we get 4 and a remainder of 448.
Write down 4 as next digit of the result. 
Result so far: 114542.46081504
If we subtract 2552 from 3000, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

After the division, we end up with 114542.46081504 and a remainder of 4.48e-07.
