Let's divide 78097291 by 402
We're looking to find how many times 402 goes into 78097291.

Let's proceed to step 1:
The number 402 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 402

Going ahead to step 2:
78 divided by 402 is 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (0) from the dividend, add it to 78, then carry on: 780 / 402

Let's proceed to step 3:
402 goes into 780 1 times with a remainder of 378.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 402 from 780 leaves us with 378.
Bring next digit (9) of the dividend behind the 378 and repeat the process: 3789 / 402

Going ahead to step 4:
3789 divided by 402 is 9 with a remainder of 171.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 3618 from 3789, we get 171.
Include the next digit (7) from the dividend after 171, then repeat: 1717 / 402

Advancing to step 5:
402 goes into 1717 4 times with a remainder of 109.
Use 4 as the next digit of our solution. 
Result so far: 194.0
If we subtract 1608 from 1717, we get 109.
Fetch the next digit (2) from the dividend, attach it to 109 and continue: 1092 / 402

Moving on to step 6:
402 can be fit into 1092 2 times, resulting in a remainder of 288.
The next digit of our result is 2. 
Result so far: 1942.0
If we take 804 away from 1092, we end up with 288.
Grab the next digit (9) from the dividend, add it to 288, then carry on: 2889 / 402

Let's proceed to step 7:
When dividing 2889 by 402, we get 7 with a remainder of 75.
The next digit of our result is 7. 
Result so far: 19427.0
Subtracting 2814 from 2889 leaves us with 75.
Fetch the next digit (1) from the dividend, attach it to 75 and continue: 751 / 402

On to step 8:
If we divide 751 by 402, we get 1 and a remainder of 349.
Use 1 as the next digit of our solution. 
Result so far: 194271.0
Deduct 402 from 751 and we're left with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

On to step 9:
402 can be fit into 3490 8 times, resulting in a remainder of 274.
The number 8 becomes the next digit in our result. 
Result so far: 194271.8
The remainder is 274 after subtracting 3216 from 3490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 10:
2740 divided by 402 is 6 with a remainder of 328.
Use 6 as the next digit of our solution. 
Result so far: 194271.86
Subtract 2412 from 2740 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 11:
3280 divided by 402 is 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 194271.868
If we subtract 3216 from 3280, we 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.

Step 12:
402 goes into 640 1 times with a remainder of 238.
Put 1 as the next digit of the answer. 
Result so far: 194271.8681
Subtract 402 from 640 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 13:
402 goes into 2380 5 times with a remainder of 370.
The number 5 becomes the next digit in our result. 
Result so far: 194271.86815
Subtracting 2010 from 2380 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 14:
When dividing 3700 by 402, we get 9 with a remainder of 82.
The next digit of our result is 9. 
Result so far: 194271.868159
If we take 3618 away from 3700, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 15:
The number 402 fits into 820 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 194271.8681592
The remainder is 16 after subtracting 804 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 16:
402 can be fit into 160 0 times, resulting in a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 194271.8681592
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

In conclusion, the division gives 194271.8681592 with a balance of 1.6e-07.
