We divide 99515078 by 638
We're looking to find how many times 638 goes into 99515078.

Let's proceed to step 1:
The number 638 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 638

Going ahead to step 2:
When dividing 99 by 638, we get 0 with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Grab the next digit (5) from the dividend, add it to 99, then carry on: 995 / 638

Step 3:
638 goes into 995 1 times with a remainder of 357.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 638 from 995 to get 357.
Grab the next digit (1) from the dividend, add it to 357, then carry on: 3571 / 638

Going ahead to step 4:
3571 divided by 638 is 5 with a remainder of 381.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 3190 away from 3571, we end up with 381.
Take the next digit (5) from the dividend and append it to 381, then repeat: 3815 / 638

On to step 5:
3815 divided by 638 is 5 with a remainder of 625.
Use 5 as the next digit of our solution. 
Result so far: 155.0
If we take 3190 away from 3815, we end up with 625.
Fetch the next digit (0) from the dividend, attach it to 625 and continue: 6250 / 638

On to step 6:
When dividing 6250 by 638, we get 9 with a remainder of 508.
Put 9 as the next digit of the answer. 
Result so far: 1559.0
Subtracting 5742 from 6250 leaves us with 508.
Grab the next digit (7) from the dividend, add it to 508, then carry on: 5087 / 638

Advancing to step 7:
The number 638 fits into 5087 7 times, leaving a remainder of 621.
Use 7 as the next digit of our solution. 
Result so far: 15597.0
If we take 4466 away from 5087, we end up with 621.
Take the next digit (8) from the dividend and append it to 621, then repeat: 6218 / 638

On to step 8:
638 goes into 6218 9 times with a remainder of 476.
Use 9 as the next digit of our solution. 
Result so far: 155979.0
The remainder is 476 after subtracting 5742 from 6218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Going ahead to step 9:
638 can be fit into 4760 7 times, resulting in a remainder of 294.
Write down 7 as next digit of the result. 
Result so far: 155979.7
The remainder is 294 after subtracting 4466 from 4760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 10:
When dividing 2940 by 638, we get 4 with a remainder of 388.
The next digit of our result is 4. 
Result so far: 155979.74
If we take 2552 away from 2940, we end up 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.

Step 11:
When dividing 3880 by 638, we get 6 with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 155979.746
Deduct 3828 from 3880 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 12:
638 can be fit into 520 0 times, resulting in a remainder of 520.
Use 0 as the next digit of our solution. 
Result so far: 155979.746
Subtracting 0 from 520 leaves us 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.

Step 13:
The number 638 fits into 5200 8 times, leaving a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 155979.74608
Subtract 5104 from 5200 to 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.

Going ahead to step 14:
The number 638 fits into 960 1 times, leaving a remainder of 322.
The next digit of our result is 1. 
Result so far: 155979.746081
The remainder is 322 after subtracting 638 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Let's proceed to step 15:
3220 divided by 638 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 155979.7460815
Subtract 3190 from 3220 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 16:
300 divided by 638 is 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 155979.7460815
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.

The final outcome is 155979.7460815, with a leftover of 3e-07.
