We look at the division of 18986312 by 781 
We want to divide 18986312 by 781.

On to step 1:
If we divide 1 by 781, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 781

Let's proceed to step 2:
18 divided by 781 is 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 781

Moving on to step 3:
If we divide 189 by 781, we get 0 and a remainder of 189.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 189 after subtracting 0 from 189.
Take the next digit (8) from the dividend and append it to 189, then repeat: 1898 / 781

Going ahead to step 4:
When dividing 1898 by 781, we get 2 with a remainder of 336.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1562 from 1898, we get 336.
Bring next digit (6) of the dividend behind the 336 and repeat the process: 3366 / 781

Let's proceed to step 5:
781 can be fit into 3366 4 times, resulting in a remainder of 242.
Put 4 as the next digit of the answer. 
Result so far: 24.0
The remainder is 242 after subtracting 3124 from 3366.
Take the next digit (3) from the dividend and append it to 242, then repeat: 2423 / 781

Let's proceed to step 6:
The number 781 fits into 2423 3 times, leaving a remainder of 80.
Put 3 as the next digit of the answer. 
Result so far: 243.0
If we take 2343 away from 2423, we end up with 80.
Bring next digit (1) of the dividend behind the 80 and repeat the process: 801 / 781

Going ahead to step 7:
801 divided by 781 is 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 2431.0
Subtract 781 from 801 to get 20.
Fetch the next digit (2) from the dividend, attach it to 20 and continue: 202 / 781

Going ahead to step 8:
781 goes into 202 0 times with a remainder of 202.
Put 0 as the next digit of the answer. 
Result so far: 24310.0
If we subtract 0 from 202, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 9:
2020 divided by 781 is 2 with a remainder of 458.
Use 2 as the next digit of our solution. 
Result so far: 24310.2
Subtracting 1562 from 2020 leaves us with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

On to step 10:
781 can be fit into 4580 5 times, resulting in a remainder of 675.
The number 5 becomes the next digit in our result. 
Result so far: 24310.25
Deduct 3905 from 4580 and we're left with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Advancing to step 11:
781 can be fit into 6750 8 times, resulting in a remainder of 502.
Record the quotient 8 as the next digit in the result. 
Result so far: 24310.258
Deduct 6248 from 6750 and we're left with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Advancing to step 12:
781 can be fit into 5020 6 times, resulting in a remainder of 334.
Record the quotient 6 as the next digit in the result. 
Result so far: 24310.2586
Deduct 4686 from 5020 and we're left with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Moving on to step 13:
781 goes into 3340 4 times with a remainder of 216.
Record the quotient 4 as the next digit in the result. 
Result so far: 24310.25864
Deduct 3124 from 3340 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 14:
The number 781 fits into 2160 2 times, leaving a remainder of 598.
Put 2 as the next digit of the answer. 
Result so far: 24310.258642
Subtracting 1562 from 2160 leaves us with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Step 15:
When dividing 5980 by 781, we get 7 with a remainder of 513.
The number 7 becomes the next digit in our result. 
Result so far: 24310.2586427
Subtracting 5467 from 5980 leaves us with 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

On to step 16:
The number 781 fits into 5130 6 times, leaving a remainder of 444.
Write down 6 as next digit of the result. 
Result so far: 24310.25864276
Subtracting 4686 from 5130 leaves us with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

In conclusion, the division gives 24310.25864276 with a balance of 4.44e-07.
