87731034 divided by 638 
Let's see how many times 638 fits into 87731034.

On to step 1:
8 divided by 638 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 638

On to step 2:
638 goes into 87 0 times with a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Take the next digit (7) from the dividend and append it to 87, then repeat: 877 / 638

Let's proceed to step 3:
When dividing 877 by 638, we get 1 with a remainder of 239.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 239 after subtracting 638 from 877.
Fetch the next digit (3) from the dividend, attach it to 239 and continue: 2393 / 638

On to step 4:
When dividing 2393 by 638, we get 3 with a remainder of 479.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 479 after subtracting 1914 from 2393.
Take the next digit (1) from the dividend and append it to 479, then repeat: 4791 / 638

Moving on to step 5:
638 can be fit into 4791 7 times, resulting in a remainder of 325.
Put 7 as the next digit of the answer. 
Result so far: 137.0
Deduct 4466 from 4791 and we're left with 325.
Grab the next digit (0) from the dividend, add it to 325, then carry on: 3250 / 638

Step 6:
The number 638 fits into 3250 5 times, leaving a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 1375.0
If we subtract 3190 from 3250, we get 60.
Grab the next digit (3) from the dividend, add it to 60, then carry on: 603 / 638

Let's proceed to step 7:
If we divide 603 by 638, we get 0 and a remainder of 603.
Write down 0 as next digit of the result. 
Result so far: 13750.0
Subtracting 0 from 603 leaves us with 603.
Grab the next digit (4) from the dividend, add it to 603, then carry on: 6034 / 638

On to step 8:
The number 638 fits into 6034 9 times, leaving a remainder of 292.
Put 9 as the next digit of the answer. 
Result so far: 137509.0
The remainder is 292 after subtracting 5742 from 6034.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 9:
The number 638 fits into 2920 4 times, leaving a remainder of 368.
The next digit of our result is 4. 
Result so far: 137509.4
If we take 2552 away from 2920, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 10:
When dividing 3680 by 638, we get 5 with a remainder of 490.
The next digit of our result is 5. 
Result so far: 137509.45
Subtracting 3190 from 3680 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 11:
638 can be fit into 4900 7 times, resulting in a remainder of 434.
Put 7 as the next digit of the answer. 
Result so far: 137509.457
If we subtract 4466 from 4900, we get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Moving on to step 12:
The number 638 fits into 4340 6 times, leaving a remainder of 512.
Put 6 as the next digit of the answer. 
Result so far: 137509.4576
If we take 3828 away from 4340, we end up with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Step 13:
The number 638 fits into 5120 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 137509.45768
Subtract 5104 from 5120 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
When dividing 160 by 638, we get 0 with a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 137509.45768
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 15:
If we divide 1600 by 638, we get 2 and a remainder of 324.
Use 2 as the next digit of our solution. 
Result so far: 137509.4576802
If we subtract 1276 from 1600, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Step 16:
The number 638 fits into 3240 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 137509.45768025
Subtract 3190 from 3240 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 137509.45768025, with a leftover of 5e-08.
