We look at the division of 63989027 by 781 
We want to divide 63989027 by 781.

Step 1:
If we divide 6 by 781, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 781

Advancing to step 2:
63 divided by 781 is 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 781

Going ahead to step 3:
781 goes into 639 0 times with a remainder of 639.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 639 and we're left with 639.
Bring next digit (8) of the dividend behind the 639 and repeat the process: 6398 / 781

Advancing to step 4:
If we divide 6398 by 781, we get 8 and a remainder of 150.
The next digit of our result is 8. 
Result so far: 8.0
If we take 6248 away from 6398, we end up with 150.
Include the next digit (9) from the dividend after 150, then repeat: 1509 / 781

Let's proceed to step 5:
If we divide 1509 by 781, we get 1 and a remainder of 728.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we subtract 781 from 1509, we get 728.
Include the next digit (0) from the dividend after 728, then repeat: 7280 / 781

Let's proceed to step 6:
If we divide 7280 by 781, we get 9 and a remainder of 251.
The number 9 becomes the next digit in our result. 
Result so far: 819.0
If we subtract 7029 from 7280, we get 251.
Bring next digit (2) of the dividend behind the 251 and repeat the process: 2512 / 781

On to step 7:
2512 divided by 781 is 3 with a remainder of 169.
The next digit of our result is 3. 
Result so far: 8193.0
Subtracting 2343 from 2512 leaves us with 169.
Append the next digit (7) from the dividend to 169 and continue with: 1697 / 781

On to step 8:
781 can be fit into 1697 2 times, resulting in a remainder of 135.
The number 2 becomes the next digit in our result. 
Result so far: 81932.0
The remainder is 135 after subtracting 1562 from 1697.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 9:
The number 781 fits into 1350 1 times, leaving a remainder of 569.
The next digit of our result is 1. 
Result so far: 81932.1
The remainder is 569 after subtracting 781 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Going ahead to step 10:
781 can be fit into 5690 7 times, resulting in a remainder of 223.
The next digit of our result is 7. 
Result so far: 81932.17
Deduct 5467 from 5690 and we're left with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

On to step 11:
781 can be fit into 2230 2 times, resulting in a remainder of 668.
Record the quotient 2 as the next digit in the result. 
Result so far: 81932.172
Subtract 1562 from 2230 to get 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

On to step 12:
781 can be fit into 6680 8 times, resulting in a remainder of 432.
Use 8 as the next digit of our solution. 
Result so far: 81932.1728
If we take 6248 away from 6680, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 13:
781 can be fit into 4320 5 times, resulting in a remainder of 415.
The number 5 becomes the next digit in our result. 
Result so far: 81932.17285
Deduct 3905 from 4320 and we're left with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Let's proceed to step 14:
781 goes into 4150 5 times with a remainder of 245.
Record the quotient 5 as the next digit in the result. 
Result so far: 81932.172855
If we take 3905 away from 4150, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Our division results in 81932.172855 with a remaining 2.45e-05.
