The aim is to understand the frequency of 781 in 49888782.

On to step 1:
4 divided by 781 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 781

Advancing to step 2:
49 divided by 781 is 0 with a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Take the next digit (8) from the dividend and append it to 49, then repeat: 498 / 781

Step 3:
781 can be fit into 498 0 times, resulting in a remainder of 498.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 498 leaves us with 498.
Fetch the next digit (8) from the dividend, attach it to 498 and continue: 4988 / 781

Advancing to step 4:
If we divide 4988 by 781, we get 6 and a remainder of 302.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 4686 from 4988 to get 302.
Fetch the next digit (8) from the dividend, attach it to 302 and continue: 3028 / 781

Step 5:
781 can be fit into 3028 3 times, resulting in a remainder of 685.
Put 3 as the next digit of the answer. 
Result so far: 63.0
If we subtract 2343 from 3028, we get 685.
Grab the next digit (7) from the dividend, add it to 685, then carry on: 6857 / 781

Moving on to step 6:
6857 divided by 781 is 8 with a remainder of 609.
Record the quotient 8 as the next digit in the result. 
Result so far: 638.0
The remainder is 609 after subtracting 6248 from 6857.
Include the next digit (8) from the dividend after 609, then repeat: 6098 / 781

Let's proceed to step 7:
6098 divided by 781 is 7 with a remainder of 631.
Use 7 as the next digit of our solution. 
Result so far: 6387.0
Subtract 5467 from 6098 to get 631.
Take the next digit (2) from the dividend and append it to 631, then repeat: 6312 / 781

Advancing to step 8:
When dividing 6312 by 781, we get 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 63878.0
Subtract 6248 from 6312 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
If we divide 640 by 781, we get 0 and a remainder of 640.
The next digit of our result is 0. 
Result so far: 63878.0
Subtract 0 from 640 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 10:
When dividing 6400 by 781, we get 8 with a remainder of 152.
Write down 8 as next digit of the result. 
Result so far: 63878.08
Subtracting 6248 from 6400 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 11:
The number 781 fits into 1520 1 times, leaving a remainder of 739.
Write down 1 as next digit of the result. 
Result so far: 63878.081
If we subtract 781 from 1520, we get 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

Going ahead to step 12:
The number 781 fits into 7390 9 times, leaving a remainder of 361.
Write down 9 as next digit of the result. 
Result so far: 63878.0819
If we subtract 7029 from 7390, we get 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Advancing to step 13:
781 goes into 3610 4 times with a remainder of 486.
The next digit of our result is 4. 
Result so far: 63878.08194
Subtract 3124 from 3610 to get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Advancing to step 14:
4860 divided by 781 is 6 with a remainder of 174.
Record the quotient 6 as the next digit in the result. 
Result so far: 63878.081946
If we subtract 4686 from 4860, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 15:
If we divide 1740 by 781, we get 2 and a remainder of 178.
Record the quotient 2 as the next digit in the result. 
Result so far: 63878.0819462
Subtract 1562 from 1740 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 16:
The number 781 fits into 1780 2 times, leaving a remainder of 218.
Write down 2 as next digit of the result. 
Result so far: 63878.08194622
Subtract 1562 from 1780 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

The quotient of the division is 63878.08194622, and the remainder is 2.18e-07.
