We look at the division of 53861867 by 781 
Let's see how many times 781 fits into 53861867.

On to step 1:
781 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 781

Step 2:
53 divided by 781 is 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Take the next digit (8) from the dividend and append it to 53, then repeat: 538 / 781

On to step 3:
If we divide 538 by 781, we get 0 and a remainder of 538.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 538 after subtracting 0 from 538.
Append the next digit (6) from the dividend to 538 and continue with: 5386 / 781

Going ahead to step 4:
If we divide 5386 by 781, we get 6 and a remainder of 700.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 700 after subtracting 4686 from 5386.
Take the next digit (1) from the dividend and append it to 700, then repeat: 7001 / 781

Moving on to step 5:
If we divide 7001 by 781, we get 8 and a remainder of 753.
Write down 8 as next digit of the result. 
Result so far: 68.0
If we subtract 6248 from 7001, we get 753.
Grab the next digit (8) from the dividend, add it to 753, then carry on: 7538 / 781

Advancing to step 6:
781 goes into 7538 9 times with a remainder of 509.
The number 9 becomes the next digit in our result. 
Result so far: 689.0
Subtracting 7029 from 7538 leaves us with 509.
Take the next digit (6) from the dividend and append it to 509, then repeat: 5096 / 781

Step 7:
The number 781 fits into 5096 6 times, leaving a remainder of 410.
The number 6 becomes the next digit in our result. 
Result so far: 6896.0
Subtracting 4686 from 5096 leaves us with 410.
Include the next digit (7) from the dividend after 410, then repeat: 4107 / 781

Let's proceed to step 8:
If we divide 4107 by 781, we get 5 and a remainder of 202.
The next digit of our result is 5. 
Result so far: 68965.0
If we subtract 3905 from 4107, 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.

Let's proceed to step 9:
2020 divided by 781 is 2 with a remainder of 458.
Write down 2 as next digit of the result. 
Result so far: 68965.2
If we subtract 1562 from 2020, we get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Advancing to step 10:
If we divide 4580 by 781, we get 5 and a remainder of 675.
Put 5 as the next digit of the answer. 
Result so far: 68965.25
If we subtract 3905 from 4580, we get 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Moving on to step 11:
781 goes into 6750 8 times with a remainder of 502.
The next digit of our result is 8. 
Result so far: 68965.258
Subtract 6248 from 6750 to get 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:
5020 divided by 781 is 6 with a remainder of 334.
Record the quotient 6 as the next digit in the result. 
Result so far: 68965.2586
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:
If we divide 3340 by 781, we get 4 and a remainder of 216.
The next digit of our result is 4. 
Result so far: 68965.25864
The remainder is 216 after subtracting 3124 from 3340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 14:
When dividing 2160 by 781, we get 2 with a remainder of 598.
The next digit of our result is 2. 
Result so far: 68965.258642
If we subtract 1562 from 2160, we get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Going ahead to 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: 68965.2586427
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.

Moving on to step 16:
5130 divided by 781 is 6 with a remainder of 444.
The number 6 becomes the next digit in our result. 
Result so far: 68965.25864276
The remainder is 444 after subtracting 4686 from 5130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

After the division, we end up with 68965.25864276 and a remainder of 4.44e-07.
