781986 ÷ 99 
Our goal is to divide 781986 by 99.

Moving on to step 1:
If we divide 7 by 99, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 99

On to step 2:
If we divide 78 by 99, we get 0 and a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Take the next digit (1) from the dividend and append it to 78, then repeat: 781 / 99

Let's proceed to step 3:
99 can be fit into 781 7 times, resulting in a remainder of 88.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 693 from 781 and we're left with 88.
Bring next digit (9) of the dividend behind the 88 and repeat the process: 889 / 99

Step 4:
99 goes into 889 8 times with a remainder of 97.
Put 8 as the next digit of the answer. 
Result so far: 78.0
If we take 792 away from 889, we end up with 97.
Bring next digit (8) of the dividend behind the 97 and repeat the process: 978 / 99

Step 5:
99 goes into 978 9 times with a remainder of 87.
Put 9 as the next digit of the answer. 
Result so far: 789.0
If we take 891 away from 978, we end up with 87.
Fetch the next digit (6) from the dividend, attach it to 87 and continue: 876 / 99

Let's proceed to step 6:
The number 99 fits into 876 8 times, leaving a remainder of 84.
The number 8 becomes the next digit in our result. 
Result so far: 7898.0
Deduct 792 from 876 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 7:
99 can be fit into 840 8 times, resulting in a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 7898.8
Deduct 792 from 840 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 8:
When dividing 480 by 99, we get 4 with a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 7898.84
Subtract 396 from 480 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 9:
When dividing 840 by 99, we get 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 7898.848
Deduct 792 from 840 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
99 can be fit into 480 4 times, resulting in a remainder of 84.
The next digit of our result is 4. 
Result so far: 7898.8484
If we subtract 396 from 480, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 11:
When dividing 840 by 99, we get 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 7898.84848
If we take 792 away from 840, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
The number 99 fits into 480 4 times, leaving a remainder of 84.
The next digit of our result is 4. 
Result so far: 7898.848484
If we subtract 396 from 480, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 13:
When dividing 840 by 99, we get 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 7898.8484848
The remainder is 48 after subtracting 792 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 14:
The number 99 fits into 480 4 times, leaving a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 7898.84848484
Subtracting 396 from 480 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The quotient of the division is 7898.84848484, and the remainder is 8.4e-08.
