We look at the division of 7784881 by 402 
We're looking to find how many times 402 goes into 7784881.

Moving on to step 1:
If we divide 7 by 402, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 402

Step 2:
402 goes into 77 0 times with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Fetch the next digit (8) from the dividend, attach it to 77 and continue: 778 / 402

On to step 3:
402 can be fit into 778 1 times, resulting in a remainder of 376.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 402 away from 778, we end up with 376.
Take the next digit (4) from the dividend and append it to 376, then repeat: 3764 / 402

Let's proceed to step 4:
If we divide 3764 by 402, we get 9 and a remainder of 146.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 3618 from 3764 and we're left with 146.
Bring next digit (8) of the dividend behind the 146 and repeat the process: 1468 / 402

On to step 5:
402 can be fit into 1468 3 times, resulting in a remainder of 262.
Record the quotient 3 as the next digit in the result. 
Result so far: 193.0
Subtract 1206 from 1468 to get 262.
Fetch the next digit (8) from the dividend, attach it to 262 and continue: 2628 / 402

Advancing to step 6:
The number 402 fits into 2628 6 times, leaving a remainder of 216.
Use 6 as the next digit of our solution. 
Result so far: 1936.0
If we take 2412 away from 2628, we end up with 216.
Append the next digit (1) from the dividend to 216 and continue with: 2161 / 402

Going ahead to step 7:
If we divide 2161 by 402, we get 5 and a remainder of 151.
Write down 5 as next digit of the result. 
Result so far: 19365.0
Deduct 2010 from 2161 and we're left with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Moving on to step 8:
If we divide 1510 by 402, we get 3 and a remainder of 304.
Record the quotient 3 as the next digit in the result. 
Result so far: 19365.3
If we take 1206 away from 1510, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 9:
402 goes into 3040 7 times with a remainder of 226.
Write down 7 as next digit of the result. 
Result so far: 19365.37
The remainder is 226 after subtracting 2814 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 10:
When dividing 2260 by 402, we get 5 with a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 19365.375
Deduct 2010 from 2260 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 11:
2500 divided by 402 is 6 with a remainder of 88.
Put 6 as the next digit of the answer. 
Result so far: 19365.3756
If we subtract 2412 from 2500, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 12:
880 divided by 402 is 2 with a remainder of 76.
The next digit of our result is 2. 
Result so far: 19365.37562
If we take 804 away from 880, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 13:
760 divided by 402 is 1 with a remainder of 358.
Use 1 as the next digit of our solution. 
Result so far: 19365.375621
If we take 402 away from 760, we end up with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Moving on to step 14:
402 can be fit into 3580 8 times, resulting in a remainder of 364.
The number 8 becomes the next digit in our result. 
Result so far: 19365.3756218
If we take 3216 away from 3580, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Let's proceed to step 15:
402 can be fit into 3640 9 times, resulting in a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 19365.37562189
Deduct 3618 from 3640 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 19365.37562189 with a remainder of 2.2e-08.
