Let's divide 18531231 by 787
We want to figure out the number of times 18531231 can be divided by 787.

Step 1:
787 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 787

Step 2:
787 goes into 18 0 times with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 787

Advancing to step 3:
185 divided by 787 is 0 with a remainder of 185.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 185 to get 185.
Bring next digit (3) of the dividend behind the 185 and repeat the process: 1853 / 787

On to step 4:
The number 787 fits into 1853 2 times, leaving a remainder of 279.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1574 from 1853 leaves us with 279.
Bring next digit (1) of the dividend behind the 279 and repeat the process: 2791 / 787

Step 5:
787 can be fit into 2791 3 times, resulting in a remainder of 430.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we take 2361 away from 2791, we end up with 430.
Include the next digit (2) from the dividend after 430, then repeat: 4302 / 787

On to step 6:
4302 divided by 787 is 5 with a remainder of 367.
Use 5 as the next digit of our solution. 
Result so far: 235.0
If we subtract 3935 from 4302, we get 367.
Fetch the next digit (3) from the dividend, attach it to 367 and continue: 3673 / 787

Let's proceed to step 7:
787 goes into 3673 4 times with a remainder of 525.
The next digit of our result is 4. 
Result so far: 2354.0
If we take 3148 away from 3673, we end up with 525.
Bring next digit (1) of the dividend behind the 525 and repeat the process: 5251 / 787

Moving on to step 8:
The number 787 fits into 5251 6 times, leaving a remainder of 529.
The number 6 becomes the next digit in our result. 
Result so far: 23546.0
The remainder is 529 after subtracting 4722 from 5251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

On to step 9:
When dividing 5290 by 787, we get 6 with a remainder of 568.
Put 6 as the next digit of the answer. 
Result so far: 23546.6
If we take 4722 away from 5290, we end up with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Going ahead to step 10:
787 can be fit into 5680 7 times, resulting in a remainder of 171.
Use 7 as the next digit of our solution. 
Result so far: 23546.67
Subtracting 5509 from 5680 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Moving on to step 11:
787 can be fit into 1710 2 times, resulting in a remainder of 136.
The number 2 becomes the next digit in our result. 
Result so far: 23546.672
The remainder is 136 after subtracting 1574 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 12:
787 goes into 1360 1 times with a remainder of 573.
Record the quotient 1 as the next digit in the result. 
Result so far: 23546.6721
Subtract 787 from 1360 to get 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Let's proceed to step 13:
787 goes into 5730 7 times with a remainder of 221.
Record the quotient 7 as the next digit in the result. 
Result so far: 23546.67217
If we subtract 5509 from 5730, we get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Advancing to step 14:
When dividing 2210 by 787, we get 2 with a remainder of 636.
Record the quotient 2 as the next digit in the result. 
Result so far: 23546.672172
Subtract 1574 from 2210 to get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Advancing to step 15:
787 can be fit into 6360 8 times, resulting in a remainder of 64.
The next digit of our result is 8. 
Result so far: 23546.6721728
Deduct 6296 from 6360 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 16:
640 divided by 787 is 0 with a remainder of 640.
Write down 0 as next digit of the result. 
Result so far: 23546.6721728
Subtracting 0 from 640 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The final result is 23546.6721728 with a remainder of 6.4e-07.
