We're dividing 73187753 by 638 
We're looking to find how many times 638 goes into 73187753.

Step 1:
638 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 638

Step 2:
If we divide 73 by 638, we get 0 and a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Grab the next digit (1) from the dividend, add it to 73, then carry on: 731 / 638

Let's proceed to step 3:
If we divide 731 by 638, we get 1 and a remainder of 93.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 638 from 731 leaves us with 93.
Include the next digit (8) from the dividend after 93, then repeat: 938 / 638

Step 4:
638 goes into 938 1 times with a remainder of 300.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 638 from 938 leaves us with 300.
Fetch the next digit (7) from the dividend, attach it to 300 and continue: 3007 / 638

Going ahead to step 5:
638 can be fit into 3007 4 times, resulting in a remainder of 455.
The next digit of our result is 4. 
Result so far: 114.0
If we take 2552 away from 3007, we end up with 455.
Grab the next digit (7) from the dividend, add it to 455, then carry on: 4557 / 638

Let's proceed to step 6:
638 can be fit into 4557 7 times, resulting in a remainder of 91.
Put 7 as the next digit of the answer. 
Result so far: 1147.0
The remainder is 91 after subtracting 4466 from 4557.
Include the next digit (5) from the dividend after 91, then repeat: 915 / 638

Step 7:
If we divide 915 by 638, we get 1 and a remainder of 277.
The next digit of our result is 1. 
Result so far: 11471.0
Deduct 638 from 915 and we're left with 277.
Include the next digit (3) from the dividend after 277, then repeat: 2773 / 638

Moving on to step 8:
When dividing 2773 by 638, we get 4 with a remainder of 221.
Use 4 as the next digit of our solution. 
Result so far: 114714.0
If we take 2552 away from 2773, we end up with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Moving on to step 9:
If we divide 2210 by 638, we get 3 and a remainder of 296.
The number 3 becomes the next digit in our result. 
Result so far: 114714.3
Subtracting 1914 from 2210 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Step 10:
638 can be fit into 2960 4 times, resulting in a remainder of 408.
Put 4 as the next digit of the answer. 
Result so far: 114714.34
Subtracting 2552 from 2960 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Let's proceed to step 11:
638 goes into 4080 6 times with a remainder of 252.
The number 6 becomes the next digit in our result. 
Result so far: 114714.346
Deduct 3828 from 4080 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 12:
The number 638 fits into 2520 3 times, leaving a remainder of 606.
Record the quotient 3 as the next digit in the result. 
Result so far: 114714.3463
Deduct 1914 from 2520 and we're left with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Step 13:
The number 638 fits into 6060 9 times, leaving a remainder of 318.
The next digit of our result is 9. 
Result so far: 114714.34639
Deduct 5742 from 6060 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Going ahead to step 14:
638 can be fit into 3180 4 times, resulting in a remainder of 628.
Put 4 as the next digit of the answer. 
Result so far: 114714.346394
If we take 2552 away from 3180, we end up with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Moving on to step 15:
When dividing 6280 by 638, we get 9 with a remainder of 538.
Write down 9 as next digit of the result. 
Result so far: 114714.3463949
Subtracting 5742 from 6280 leaves us with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

On to step 16:
If we divide 5380 by 638, we get 8 and a remainder of 276.
The next digit of our result is 8. 
Result so far: 114714.34639498
The remainder is 276 after subtracting 5104 from 5380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

In conclusion, the division gives 114714.34639498 with a balance of 2.76e-07.
