We divide 80653583 by 638
We want to figure out the number of times 80653583 can be divided by 638.

Let's proceed to step 1:
638 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 638

On to step 2:
When dividing 80 by 638, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Include the next digit (6) from the dividend after 80, then repeat: 806 / 638

Going ahead to step 3:
The number 638 fits into 806 1 times, leaving a remainder of 168.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 638 away from 806, we end up with 168.
Take the next digit (5) from the dividend and append it to 168, then repeat: 1685 / 638

Going ahead to step 4:
When dividing 1685 by 638, we get 2 with a remainder of 409.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 1276 from 1685 to get 409.
Bring next digit (3) of the dividend behind the 409 and repeat the process: 4093 / 638

Moving on to step 5:
If we divide 4093 by 638, we get 6 and a remainder of 265.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
The remainder is 265 after subtracting 3828 from 4093.
Fetch the next digit (5) from the dividend, attach it to 265 and continue: 2655 / 638

Step 6:
When dividing 2655 by 638, we get 4 with a remainder of 103.
The next digit of our result is 4. 
Result so far: 1264.0
Subtracting 2552 from 2655 leaves us with 103.
Bring next digit (8) of the dividend behind the 103 and repeat the process: 1038 / 638

On to step 7:
638 can be fit into 1038 1 times, resulting in a remainder of 400.
Put 1 as the next digit of the answer. 
Result so far: 12641.0
Deduct 638 from 1038 and we're left with 400.
Append the next digit (3) from the dividend to 400 and continue with: 4003 / 638

Going ahead to step 8:
638 can be fit into 4003 6 times, resulting in a remainder of 175.
The number 6 becomes the next digit in our result. 
Result so far: 126416.0
If we take 3828 away from 4003, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 9:
638 goes into 1750 2 times with a remainder of 474.
Put 2 as the next digit of the answer. 
Result so far: 126416.2
Subtracting 1276 from 1750 leaves us with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Going ahead to step 10:
When dividing 4740 by 638, we get 7 with a remainder of 274.
The number 7 becomes the next digit in our result. 
Result so far: 126416.27
Deduct 4466 from 4740 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 11:
638 goes into 2740 4 times with a remainder of 188.
Use 4 as the next digit of our solution. 
Result so far: 126416.274
If we subtract 2552 from 2740, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 12:
If we divide 1880 by 638, we get 2 and a remainder of 604.
Write down 2 as next digit of the result. 
Result so far: 126416.2742
If we subtract 1276 from 1880, we get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

On to step 13:
When dividing 6040 by 638, we get 9 with a remainder of 298.
Put 9 as the next digit of the answer. 
Result so far: 126416.27429
Deduct 5742 from 6040 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 14:
The number 638 fits into 2980 4 times, leaving a remainder of 428.
Use 4 as the next digit of our solution. 
Result so far: 126416.274294
If we take 2552 away from 2980, we end up with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

On to step 15:
638 can be fit into 4280 6 times, resulting in a remainder of 452.
Record the quotient 6 as the next digit in the result. 
Result so far: 126416.2742946
The remainder is 452 after subtracting 3828 from 4280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Moving on to step 16:
638 can be fit into 4520 7 times, resulting in a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 126416.27429467
Deduct 4466 from 4520 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 126416.27429467 with a remainder of 5.4e-08.
